Materialism and the Contemporary
Natural Sciences
If the defeat of the Russian revolution of 1905 left a deep depression among revolutionary intellectuals and caused some of them to flee from materialism into the arms of religion and idealism, it is hardly surprising that the much more disastrous and important defeat of European socialism is accompanied by similar manifestations. Some recognizable symptoms of theoretical decay occurred in advance of this defeat; although they were not the primary reason for the catastrophe, they must be counted among its many causes. I refer here not only to what began under Gorbachev, but also to the theoretical dogmatism that had built up over a long period and that later characterized the political immobility of the Brezhnev era.
In the Gorbachev era, a concept was introduced that gave up
essential parts of historical materialism, Marxist political economy, and the
theory of scientific socialism. If humankind in general takes the place of
specific classes, if policy can be founded on a universal human morality, if
all this can be realized because capitalism in its inner nature has become
peaceable and therefore the future of the human species lies in the coexistence
of the two systems, if the necessity no longer exists for overcoming capitalism
by socialism, then the Marxist analysis of capitalism is wrong. In that case,
morality and the political will of the leading forces and classes become
dominant in policy over the material basis. That is the end of Marxist
historical and social theory.
Once
again a fundamental debate on materialism is taking place, especially in
Marxist philosophy. This theory is often questioned against the background of
new scientific hypotheses, theories, and perceptions, and this new intellectual
material is undoubtedly a challenge for Marxist philosophy. (The challenge is
today even greater, in actuality, for nonmaterialist philosophical schools and
tendencies.) Engels noted in Ludwig Feuerbach and the End of Classical German
Philosophy that materialism must change its form with each epoch-making
discovery in the sphere of the natural sciences (1990, 369). Since then, many
epoch-making discoveries, hypotheses, and theories have emerged that
individually and collectively demand the development of materialist philosophy.
In 1908, Lenin produced a first treatise on this matter with Materialism and
Empirio-criticism (1962).
I
suggest at least the following such new facts of natural science:
—The
special theory of relativity and the general theory of relativity.
—Quantum
theory and quantum mechanics.
—The group of self-organization theories (including the theories of chaos, catastrophe, and synergy).
—The
theory of self-reproducing prebiotic giant molecules.
—New
efforts to clarify the mechanisms of biological evolution.
—New
works of organism theory resulting from this evolution research.
—Important
new neuroscientific research (or information) on the mind and the brain.
The
discussion of the new problems for materialism assumes once again an answer to
an old question: How in general must we understand the relationship between
philosophy and the specialized sciences? Shall we follow so-called analytical
philosophy, which says that the specialized sciences are competent for the
researching of real facts and that philosophy here can find no object?
Philosophy is then reduced to analyzing the language we use to pursue science.
(Logical examinations may be also be included.)
Or
shall we follow the widely acclaimed constructivist philosophy? It analyzes our
means of gaining knowledge—that is, terms, models, patterns, and theories that
serve our understanding of the world. Very different versions are to be noted,
such as that of Hugo Dingler (1952). Dingler first derives geometry from the
manual and technical production of planes, etc., and then concludes that such
operations can only be possible because of the existence of ideas behind the
production, with the result that this version of constructivism becomes
idealism. In a second version, radical constructivism, our mental instruments
of production have no connection to the extramental—which necessarily leads to
solipsism.
Yet
another version follows Husserl, and locates the origin of our intellectual
tools in the “life-world,” or “life-world reality.” These are empty phrases; we
must ask, what is meant by “life-world,” and from what is it derived? Again
another version accepts the materiality of the tools of gaining knowledge and
recognizes that consciousness is technologically determined. Here the
transition to a materialist position seems possible. Finally we have to ask,
what is the object of philosophy, how does it differ from the specialized
sciences, and what do philosophers do when they work—that is, philosophize?
If
Planck, Einstein, Heisenberg, Schrödinger, C. F. von Weizsäcker, Haken, Eigen,
Prigogine, and others—as scientists— deal with subjects traditionally belonging
to philosophy; and if they treat them as philosophical subjects (especially
Planck, Einstein, and Heisenberg), this reveals the existence of an object of
philosophy not taken care of by the analytical or constructivist approach.
Of
course, philosophy must endeavor to use clean tools of work, clear instruments
of thinking, and in this regard can learn from analytical and constructivist
philosophy. The tools of exact thinking cannot be equated with the objective
reality to which they refer. But also the opposite error must be avoided: We
cannot ignore that they not only are a product of the subject, that is, our
construction, but that within them occurs the connection of the subjective with
the objective; only then do they gain the power of reality. Philosophy
(“thinking about thinking,” as Hegel called it) transcends the analysis of the
subjective side of the process of perception, and deals with the subjective
side in its connection with the object.
When
philosophers work, of course, they do not measure, weigh, calculate, and
experiment with objective things. Their business is to prove our mental tools of
production. But are there characteristics that the thinking-tools of the
specialized sciences possess that are generally applicable to each scientific
act of ºcognition? The question seeks in the process of cognition the general,
which transcends each of the special kinds of perception or research—the
conception of laws or the principle of causality, for instance. Then the
question is about the relationship of such means to the reality to which they
refer, even about this reality itself, and the means for investigation that are
applied in the specialized sciences, and if these means can also be
generalized, for instance, in the concept of practice. While using these mental
tools, philosophers may also experiment with thoughts as natural science does
(just think of Einstein’s thought-experiments on the general theory of
relativity). But this is an entirely different way of establishing the mental
tools from that which is needed in analytical philosophy. And all this leads to
the question of whether an overall objective reality and general patterns of
development exist. If so, they would then be genuine objects of philosophy. In
other words: If philosophy thinks about matter, space, time, quality, and
quantity, it reflects first of all objective connections. To be able to do so,
to perceive the generalizable in the results of the specialized sciences,
philosophy must make an effort to stay in close contact with the sciences if it
itself is to be scientific.
Materialism and relativity
theory
The
special theory of relativity is based on the fact that the speed of light is
the limit for the speed of material systems, Moreover, the speed of light is
the same regardless of the relative motion of the source of light toward or
away from the system. The relative speed of two independently moving objects,
when calculated by adding or subtracting the speeds of each in some coordinate
system, depending on whether they are approaching or receding from each other,
becomes increasingly invalid as the speeds take on values closer to the speed
of light. This is only possible if in a process of acceleration approaching the
speed of light, the space-time conditions of the moving system change in such a
way that the division of distance by time approaches the value of the speed of
light. This again signifies that absolute space and time do not exist
independently of a material frame of reference. In his general theory of
relativity in 1915, Einstein established that the properties of space and time
are both necessarily connected with the distribution of matter.
In
his studies of the dialectics of nature, Engels had already defended the view,
held before him by Feuerbach, that space and time were inseparable qualities of
matter (he used the word “matter,” not “mass”). So this actually must not shock
materialists. It was the conclusion that was shocking—that mass, space, and
time alter in connection with processes of motion.
But
of course Engels could not discuss the far-reaching results that derive from
the relativity theory. In 1908 Lenin, even though he discussed works close to
the theory of relativity, like those of Poincaré, referred only to the
variability of mass with speed (1962, 260)—one of the results of Einstein’s
1905 paper on the special theory of relativity—and concluded that this was not
a problem for the dialectical-materialist concept of matter.
From
Einstein’s theory of special relativity, another conclusion follows: that the
speed of light, as a limiting speed of moving objects, can only be understood
from what is changing in a system, that is, from the energy of mass in motion.
When the speed of an object increases, its mass also increases. As a result,
successive incremental increases in speed require successively greater
incremental increases in the energy added to the moving object. As an object
approaches the speed of light, its mass increases without limit so that an
infinite amount of energy—an impossibility—would be needed to reach the speed
of light. Dialectical materialists have often misunderstood this, because they
have confused the relationship among mass, energy, and matter— that is to say,
qualitative attributes of matter with matter itself! Mass and energy are not
modes of matter but attributes (or properties) of matter, since there is no
mode of existence of matter that does not have both mass and energy associated
with it.
Energy
and mass are often treated as interchangeable with each other because of their
proportional quantitative relationship in Einstein’s formula E = mc2.
Energy is the measure of the capacity of a physical system to undergo change
from one mode of existence to matter another (Marquit 1980, 83). Mass is
related to the inertial property of matter—that is, mass is a measure of the
resistance of a material object to a change in velocity (Newton 1:2).
The
proportionality of mass and energy was important for the utilization of nuclear
energy. It is mentioned here because it is another confirmation of the special
theory of relativity. It was confirmed as a proof through practice that spoke
and still speaks in favor of this theory.
At this
point, the relationship between the general and the specific must be
considered. Comprehension of matter in general must be distinguished from the
concrete knowledge we gain from physical, chemical, biological, and social
matter in certain historical contexts. A term used in natural sciences to
signify what is known at the time about matter is the specific. This
knowledge was, of course, different in the last century from today. To use an
analogy: The universe and those ideas we have of it in certain historical
periods are to be distinguished. Where do I see the analogy to the special (and
also to the general) theory of relativity? Consistent materialist thinking says
that the universe neither has been created nor will it dissolve into nothing.
How can terms that refer to something measurable—as do the terms space
and time—be applied to something that in principle is not measurable? Or
else someone first must show me how to measure the infinite! Measuring only
works in relationship to something concrete that we extract from the infinite
and use as a ruler. But is it not obvious that in relation to the infinite,
every quantified size is trifling? It is a paradox to speak of space and time
involving the infinite. For both terms derive from the concrete state of the
universe we live in. They are something specific, not to be identified with the
general they belong to. We can see this already when, to be able to speak about
the infinite, we need the denial of space and time We can only speak of them by
smuggling their negation into the comprehension of them. This often happens
unconsciously: infinite or endless means not ending. As
some philosophers and physicists at the turn of the century subordinated the
general—matter—to the specific—the changing forms of mass, energy,
elements—”matter” suddenly got “lost.” Theoretical physicists who do research
on problems of cosmology say that space and time had their origin in a “big
bang.” Materialists take offense at this, because in a way it ends with the
thesis that God created the world out of nothing.
But is
this logical? When physicists speak about what they know about their object of
research and say they are talking about matter, they substitute their
concrete knowledge of aspects of matter for matter itself (as suggested above).
Now I
once again come back to the subject of space and time. Space and time, as they
exist in the “known” universe (including the way we are built into them)
actually do have their origin in the “big bang.” But just as the present state
of the universe “known” to us began with the “big bang” hypothesis (I deal here
only with the general hypothesis, not its many different versions), but not the
universe “in itself,” thus also our ideas of space and time have their
beginning with this “big bang.” But this is only the concrete appearance of
matter. Matter itself includes more, is even more general than the “known”
universe and conceptions of time and space acting within it. As far as I can see,
we have not yet have created terms for this, unless we are satisfied with the
negative definition un-ending or not-ending.
In any
case, we must not destroy the relationship of the specific and the general by
subordinating the latter to the former. All those who believe that space and
time exist “in themselves,” that these are not simply the terms used for their
concrete appearance in the universe known to us today but had their origin in
the “big bang,” also make the mistake of confusing the general with the
specific.
This
leads us to the general theory of relativity. The special theory of relativity
does not deal with gravity. It is known, however, that inertia and gravity act
on moving bodies: If a car brakes, inertia keeps moving it forward—we all know
the problem. So when analyzing processes of motion, one cannot ignore the
effects of inertia and gravity. Einstein assumed that gravity and inertia are
identical. Without mass, neither gravity nor inertia exists. Whether changes of
a moving system depend on one or the other of the two forces (which are
identical anyway) cannot be distinguished, and in any case both are due to the
mass present.
The
general theory of relativity led to a new cosmological theory, which I refer to
here only insofar as it is essential for the present purpose. Shortly after
formulating his general theory of relativity, Einstein concluded that the
universe was finite in size. In 1917 he introduced a “cosmological constant”
into his equations to ensure that the size of the universe was static. In 1922
a Soviet mathematician, Alexander Friedmann, made a correction to Einstein’s
work (Einstein at first resisted but then subsequently acknowledged his error)
and showed that according to the corrected theory, the universe was expanding.
Friedmann laid the basis for what proved to be three models of such states of
motion. The first says that the universe is expanding with sufficient energy
that gravity cannot brake this process. If we follow the second model,
expansion under the effect of gravity at a certain point comes to a halt, and a
process of contraction begins. The third model assumes that the rate of
expansion gradually slows down to zero without reversing. Which of these models
is true presently cannot be said with full certainty, but four discoveries,
each made independently of one another, presently support the assumption that
the universe is in a process of indefinite expansion. These are: the Doppler
red-shift of cosmic objects, discovered by Hubble; the distribution of elements
in the universe; background radiation in the universe, which is kind of a
thunder of the big bang; and, recently, the temporal sequence of the appearance
of elements in the universe.
This
hypothesis of expansion allows us to calculate backward to the time when the
known mass of the universe was concentrated into a space of unimaginably small
size, the pressures and temperatures of this cosmos-soup finally producing the
big bang that initiated the process from which the present state of our
universe is derived.
Some
consequences and problems merit discussion here.
The
idea that the universe, though expanding, has a definite size, is associated
with the concept of the curvature of space—that is, space that closes upon
itself. This quite contrary to our intuitive notions of geometry as reflected
in Euclidean geometry.
It
follows from both Euclidean geometry and from Einstein’s general theory of
relativity that a “straight” line is the shortest distance between two points.
It is also the case in Einstein’s theory that a beam of light traces out a
“straight” (more precisely, a geodesic) line. But if mass attracts other
masses, and a beam of light on its way from the sun to earth passes close to a
planet, the beam will be slightly deflected by the gravity of the planet, and
will bend away from its original path. And since the whole universe is filled
with mass, we find these deflections everywhere, affecting the qualities of
space and time. This has caused much controversy about the sense in which we
can consider Euclidean geometry valid. Some consider it as mere idealization
and assume the real geometry of the universe to be quite different because of
its curvature. Others point out that physics as a measuring science cannot
renounce this geometry.
Discussions
about the geometrical consequences of the general theory of relativity deal
especially with the thesis of the curvature of the universe. If the universe is
curved, in analogy to the curvature of the surface of a sphere, what then
exists outside this curved space? Perhaps in answering this question in the
future, we shall encounter the problem of the general and the specific. At the
present time we can answer that the question implies an error in conception. It
applies the idea of Euclidean (a so-called flat) three-dimensional space to a
geometry that is not Euclidean. There is no inside or outside any more than
there is an inside or outside along the circumference of a circle or an
inside or an outside on the very surface of a sphere. If there were
two-dimensional creatures living only on a two-dimensional surface such that of
a sphere, they could not imagine an inside or outside—that is, the existence of
something not entirely within their two-dimensional space. So the question is
without meaning.
At the
time of the explosion, the matter of the universe was squeezed into such a tiny
space that relativity theory, which does not deal with infinitely small
quantities, cannot be applied to yield the properties of space and time. In a
certain sense, it loses its validity, and for the exploration of this state of
the universe the second of the two fundamental physical theories of the
twentieth century must be applied, namely, quantum theory. Quantum theory deals
with the states of the microworld, so that its laws are also valid in this
state of matter.
Let us
consider some things about the “big bang.” Some followers of materialism
proceed with the method of Palmström,[i] that what must not be, cannot
be—because theologians and idealists interpret the big bang as the beginning of
the world, as a creation by God, and therefore as evidence of God. Pope Pius
XI, in particular, involved himself with this. Some materialists, seeing the
theologians’ and idealists’ interpretation of the big bang as contradictory to
materialism, simply deny that the big bang occurred and are eagerly receptive
to arguments that negate it.
But
looking at it philosophically, we see that if the big bang really did occur, it
does not necessarily imply anything concerning the creation of world by God. It
only implies that in the process of development of the universe, qualitative
changes took place, and that the big bang was one of them.
Any
other conception would contradict the universality of causality. Philosophers
of nature who are no followers of dialectical materialism see this in the same
way, Barnulf Kanitscheider, a philosopher at the University of Giessen,
opposing the idea of the world’s creation out of nothing, writes:
Nothing,
if we are allowed to use this monster of a term, is no real object that could
be brought into any lawful connection with physical matter. No “something” can
be connected with “nothing.” The ontological reason for this is simple.
Negative things do not exist, to no thing belongs an antithing, nor to the
complete system an antisystem; there is no object named “nothing” opposite the
universe. Since from a conceptual fiction nothing can originate, the conception
of origin already has semantically changed if the new object has not originated
in a former physical state. (Kanitscheider 1981, 449)[ii]
Mario
Bunge calls the thesis of the reasonless origin of things pure magic
(Kanitscheider 1981, 449). Again Kanitscheider: “It makes no sense to imagine
that natural laws can be pulled out of the world like whalebones out of a corset,
and then to watch, how the lawless matter is tumbling down” (467).
To
conclude from the necessity of an origin for each single thing or phenomenon
the necessity of an origin for the whole is a faulty application of causality
for two reasons: First, it is true that each member of a club must have had a
mother, but it is not correct to conclude from this that the club must also
have had a mother. In this example the whole is perceived as a mechanical
addition of its parts and is treated the same way as its parts. Second, it is
not reasonable to assume that the world needs an origin (supposedly God) for
its existence. but that God himself needs no origin. You cannot apply the
essence of an argument, causality, and at the same time ignore it.
An
analysis of the cosmological and astrophysical materials leads to the
conclusion that an explanation of the world needs no God or any other creator,
that there is no indication of a state of nothing having preceded the existence
of our universe. As Hawking writes,
One
could say: “The boundary condition of the universe is that it has no boundary.”
The universe would be completely self-contained and not affected by anything
outside itself. It would neither be created nor destroyed. It should just BE.
(1996, 175)
Philosophically
this signifies a confirmation of the fundamental positions of materialism.
Quantum theory
Quantum
theory, initiated by Planck and further developed by Bohr, Einstein,
Heisenberg, and Schrödinger, tells us that subatomic particles exhibit both
corpuscular and wave-like properties. These two qualities exclude one
another—that is, they can never manifest themselves simultaneously in the same
experiment. These characteristics remain puzzling even today.
The
Heisenberg uncertainty principle couples the precision with which the position
of a particle is determined with a spread in the momentum of the particle. The
greater the precision to which the positions of particles are localized, the
greater the spread of the momenta. It is impossible, therefore, to impart to a
particle simultaneously an exact position and an exact momentum. Statements can
only be made about collections of such microobjects, and for this purpose a
special mathematical theory of motion, quantum mechanics, is necessary for the
microworld,
Wave-corpuscle
dualism and the uncertainty principle, briefly described here, lead to
philosophical problems. Exact physical experiments have proved that
microobjects behave both like waves and like particles, qualities that in
macrophysics cannot be possessed by one and the same object. But the
dialectical contrariety of microobjects can only exist if both qualities occur
together in the same object at the same time in the same experimental setup.
This has never been observed, For a long time, wave-particle dualism was not
viewed as a problem by dialectical materialists, since it seemed to prove the
contradictory character of microobjects. The uncertainty principle was more
troublesome since the spread in observed values of identical physical setups
appeared to undermine determinism. Quantum mechanics, in contradistinction to
Newtonian physics, was often taken as proof that events on the subatomic level
do not occur objectively and independently of the observer, but are bound to
the act of observing. This was a widely shared opinion during the first period
of the Copenhagen interpretation of quantum theory, but was later seen in
relative terms by Bohr and Heisenberg. Max Born’s remark that “the motion of
particles follows probability laws, but probability itself develops according
to causality” (Born 1969, 239) disproves the agnostic pseudoconsequences of
quantum mechanics in a way that is acceptable to materialists. We shall return to this question later in
this article.
Theories
of self-organization
The
thermodynamic theory of evolution says that in all processes involving energy
conversion, part of the energy is devaluated, which takes place physically as a
change from molecular order to molecular disorder, a process also described as
an increase of entropy, entropy being a measure of this disorder. We are
therefore dealing with a continuing process of degradation of energy to an
increasingly greater degree of disorder and disorganization. This thermodynamic
evolution theory contradicts the fact that biological evolution is not
associated with an increase in disorder and disorganization. The biological
evolution theory seems to contradict basic natural laws and therefore could be
considered as a breakdown of natural law that could only be explained by the
intervention of a supernatural power.
This
apparent contradiction was solved some years ago by the theory of
self-organization pioneered by Ilya Prigogine, a physical chemist and Nobel
Prize laureate.
If
a molecular system is undergoing changes while in a state that is far from
equilibrium, it can display two tendencies as it moves toward equilibrium.
First, just as an automobile engine exhausts gas to the atmosphere, the
molecular system can release unordered energy to its environment, resulting in
an overall increase in entropy. The energy fluctuations within the system can
encounter bifurcation points, at which paths open for the formation of more
highly ordered structures, the formation of which entails energy release to the
environment outside the system. The stability of ordered structures arises
because the energy required to disturb them has already been dispersed to the
environment and is no longer readily available. This process leaves open the
possibility of the formation of another, still higher level of organizational
structure. In this way, the contradiction between the two theories of
evolutionary development is resolved, both strictly following natural laws.
There
is no need for a miracle, for a divine, supernatural act to explain biological
development. The only possibility of avoiding this conclusion would be the
statement that the laws ruling it have been created together with the world by
an extrahuman force. But then reasonable arguments for the possibility and
necessity of this extranatural power must be found, and that cannot be
established by scientific means.
The
question then arises: Does this conception of evolution not also imply the
impossibility of predicting the future development of social systems, since at
such a bifurcation point the system staggers, fluctuates, tries to replace the
old order by a new one, but with no certainty about what will be chosen? Does
this not disprove the materialist historical conception that socialism is the
system that follows capitalism? This question alone is challenge enough for
materialism in historical and social theory.
Wherever
the materialist historical conception is viewed as a theory of an unalterable,
mechanical sequence of several social systems, that at bifurcation points only
a predetermined, one-dimensional process could develop, then this theory has
been made into a monster, deserving the criticism it receives. Hawking
correctly warns against the arbitrary application of natural laws to society:
“One has to keep the investigation of the fundamental laws of science and the
study of human behavior in separate compartments” (1993, 136). Murray
Gell-Mann, Nobel laureate in physics (creator of quark theory), referring to
the terms chaos and energy field, writes that such conceptions of
modern theories and hypotheses of natural sciences have turned originally
“useful concepts into meaningless clichés” (1994, 27).
I
also wish to recall the consequences of trying to transfer perceptions from
biological evolution theory, especially Darwin’s, to society. It is true that
theories that contradict fundamental physical laws cannot be correct. Higher
forms of systems that have undergone evolutionary development such as
biological and social systems have in common the tendency to reproduce
themselves. Self-organization is an especially high level of development,
possible only if in such a system changes do occur (for example, mutations in
biological systems), otherwise the systems would stagnate. These changes are
the material of evolution, leading to a competition among viable systems. In
this competition, the systems that survive are those that are best able to
adapt to the conditions in which they exist.
Yet
important differences exist, as has been pointed out by Ebeling:
1. The “testing” of different principles
for the activity of nonhuman living organisms is not subject to the moments of
consciousness that occur among humans in a social context as they seek ways for
optimal satisfaction of certain needs.
2. In the social sphere, technical or
social variations or mutations begin in the mental sphere with thought
experiments that can be combined with real experiments. This we do not find in
prehuman evolution.
3. In the social sphere, the selection
among possibilities of development already begins during a stage in which
actions are planned on the basis of values that follow from theoretical and
ethical standards, unlike biological systems (the simulation of chances of
survival of prebiotic or primitive biotic systems follows other norms).
4. These valuations in the social sphere
utilize collective knowledge, which today increasingly has a worldwide nature,
with the result that on the one hand, development is accelerated, while on the
other isolation causes great harm to the isolated system (1990, 671ff.
With this background, let us look at what
happened in 1989 and the following years. Was there a multiplicity of choices
for the systems that were collapsing? Was it really impossible to foresee what
would follow the breakdown?
Despite somewhat different conditions and
despite differences in the quality of the leading persons in most of the state
systems that collapsed, the question of property became the pivotal factor, so
that the former socialist ideological-political superstructure was destroyed
and replaced with a capitalist one. At the bifurcation point that was arrived
at in the social sphere, not only did unforeseeable processes take place, but
class forces encountered each other in a struggle for their interests, as is
projected in the materialist conception of history and the theory of scientific
socialism.
It should be mentioned, finally, that
theories of self-organization do not at all maintain that, in principle, the
way would be open in any direction at a bifurcation point. If they said this,
all self-organization conceptions would fail in regard to one principal
question. The abstract mathematically defined possibilities to synthesize
living substances from the available atomic materials are so many that the time
since the big bang would not have been sufficient to try them all. These
abstract possibilities, however, are limited for mathematical reasons.
The transition
from prebiotic to biotic macromolecules
The source of the origin of life is also an
old controversy between materialism and idealism. It is no wonder that among
natural scientists, materialists have tried repeatedly to solve this problem.
And indeed, the materialist position has essentially been substantiated by
Manfred Eigen’s discovery of macromolecules with the ability to store the
information necessary for their self-reproduction. Thus they possess the basic
qualities of living matter. Eigen was awarded the Nobel Prize for his
discoveries. In the chemical development of the earth, two groups of chemical substances
provided the essential combination for the origin of life. One were the nucleic
acids that were the precusors to RNA (ribonucleic acid), and the other the
amino acids that could be catalyzed into proteins (chains of amino acids) by
the RNA. The chemical and physical properties nucleic acids and proteins are
rather well-understood. It is generally believed that the further development
of RNA led to the formation of the self-reproducing molecule of DNA
(deoxyribonucleic acid). The elaboration of DNA and the processes associated
with it have earned several Nobel Prizes. Although we do not yet have all the
answers to questions about the origin of self-reproducing molecules, the
principle issue of the way living matter arises from nonliving has been clarified.
Reproduction, in which DNA, RNA and
proteins are involved, is complex and is an example of the interdependence of
many processes. Natural biochemical and biophysical laws are the basis of these
processes, but the ways in which reproduction takes place and the resulting new
organisms are related to the evolutionary and individual history of the
organisms involved. These processes are worthy of a dialectical-materialist
analysis that could prove important in the further development of the philosophy.
The process of
biological development
Living matter obviously has a great
potential for change, the characteristic of all matter. In the adjustment of
the organism to continuous changes within itself and in the environment in
which it lives, the changes that promote the integrity of the organism are
likely to persist and result in structural and functional changes of the
organism that may affect the reproductive process on all levels, including the
biochemical, that is, genes and proteins, so that offspring are also changed in
relation to the characteristics of the environment. These changes in the genes
and proteins are also affected in the new individual by the environment in
which it lives, so that those changes may or may not remain active. In all the
integrative effects of changes within and outside the organism, the activity of
the organism is potent in the processes of change and persistence in the
species. Changes in genetic material favorable for the organism’s interaction
with its environment are carried forward genetically and thereby remain
available for subsequent activities. This means that organisms undergo a kind
of learning process. They are thus the subjects and objects of evolution. They
remain within environments that offer them favorable conditions, which implies
a sort of recognition of such conditions, in contradiction to the autopoiesis
conception.
The Darwinist view of survival of the
fittest has been entrenched as indubitable knowledge, as was the case in an
earlier time when the overturning of the Ptolemaic system by Copernicus
collided with mass consciousness as well. New thinking about the evolutionary
process has questioned whether natural selection is the only fundamental
process in evolution. Developmental processes as focal points in the process of
speciation, the activity of the individual organism, and the concept of
epigenesis as incorporating environmental as well as developmental histories of
change have been stressed by a number of investigators. The positing of a mechanical
materialist dichotomy between genetic (sometimes termed “evolutionary”) factors
and environmental factors is decried by many, but the persistence of a
genetic-determinist view is evident. “Pure environmentalism” and “pure
hereditarianism” are denied, but the search for genetic bases for complex human
behavior is supported financially by genomic programs. Neither the materiality
of the environment nor of the organism are being challenged by the
aforementioned reference to a kind of learning process. Only another
subject-object relationship is being elaborated, or more accurately, the
internal conditions of the organism are seen as determined. This is only part
of the old dialectical thesis that development arises from the inner
contradictory moments. The dialectical thesis also sees development as arising
from external contradictory moments.
Important new
neuroscientific research on the mind and the brain
Neuroscience has been able to show that our
sense organs transmit chemical/electrical signals to the brain, not pictures or
copies of environmental stimuli. The dominant view is that the brain is
autonomous, responding to the environment on the basis of its internal
processes and according to them only. The brain “makes” the environment. I am
speaking about the conceptions of Maturanas, Varelas, von Foersters, and
others.
They start with the thesis that cognition
is a biological activity and has to be treated as such. This is based on the
assumption (first made in 1826 by Johannes Müller, not by the above scientists)
that the specific quality of our sense organs is that they act on our
perception. Müller had already combined this with a Kantian interpretation,
saying that we therefore are unable to perceive the world outside of us in its
objective being; autopoietics tells us the same thing. In Greek auto
means self and poiein means to make; autopoietic systems
thus are systems created by themselves.
The findings of neuroscience are new
requisites for the reflection theory of knowledge. It is necessary to examine
the results of their research in which it is clear that the nervous system
responds in organized ways to the experiences of the organism as it acts in its
environment, as for example, when a human does problem solving, or focuses on
one or another set of visual stimuli.
Must materialism fail because of criticism
of reflection theory? It would be foolish to combat the material discovered
through research on the brain. But it is another thing to deal with conclusions
drawn from the facts of the natural sciences to the field of epistemology.
Of course, the special qualities of our
sense organs influence our perception. But cognition is not only based on the
passive reflection of environmental stimuli. It is also a result of our
activity within our environment. Activity and perception must not be torn
apart. Reflections during activity are basic to the adjustment of the organism
to changes in the environment as a result of its activity. The organism
“evaluates” the sensual information and makes changes in its activity to
conform to the new information. The processes of integrating the reflections
and the changes in the environment and the organism’s activity have evolved
from those of unicellular (acellular) organisms in which the response to the
environment is transitory and not integrated for later experiences and
behavior, as in the amoeba, to the highly organized and integrated activity of
the nervous system in humans.
I cannot with the best of will understand
how the new brain physiology can sink into solipsism in relation to cognition.
Let us look at our own experience. Touching
a hot stove brings a quick withdrawal from its surface. This takes place at
first independently of our will and with knowledge of the possible ensuing pain
and damage it becomes an established pattern. The laws that govern such
activity are the same for all organisms: the intensity of the stimulus brings
about a withdrawal. When the organism is organized with a nervous system that
can integrate immediate and past experience and plan future activities, the
activity of withdrawal becomes elaborated in new patterns.
Something other than the biophysical and
biochemical laws were operative here, and they should not be forgotten or
neglected in our attempts to understand organismic activity. Individuals do not
react to the environment passively; they are active in it. Recognizing the
differences in the level of complexity and developmental patterns, we see that
each organism is continuously adjusting to internal and external changes. By
studying those similarities and differences among organisms we may arrive at
law-governed behavior.
There is a relationship between the sensual
and the rational stages of human behavior. The path does not only run from the
senses to the inner world of the brain, but also vice versa. We only perceive
when our sensual perception already contains rational moments. The inner world
of our brain is more and more taken out of its total isolation. We do not
perceive as isolated beings. We are participants in a collective experience.
And we observe what others do, beginning with the first moments of our life,
asking ourselves why they do it, why this way and not another way, trying it
ourselves, trying this and then something else, and we keep learning, learning,
and learning. One can say that there is no behavior that is not theory-laden
because of this social/societal experience.
The brain that has the capacity for
rational activity evolved as a function of the millenia of hominid experience
with members of its own species, with the animals and the environment in which
they lived. However, the organization, the neural structures and functions that
develop in any individual are unique and reflect the biochemical history of the
specific parents and of the life lived by the individual. Studies based on the
relationship between the material base of organismic structure and function and
the material base of the social/societal processes that bring about the
development of the individual are difficult to obtain. If the studies of this
relationship are not based on dialectical and historical materialism, they
swindle us, and contradict reality. We cannot fall back on Fichte’s words, “The
worse for the facts,” but the facts will instruct us in a painful way about incorrect
inferences of the products of the activity of our brain.
Moreover, even in the earliest stages of human
life we find forms of mental anticipation of results of self‑activity,
some kind of simulation of the action before it is carried out, in order to
establish what kind of results are to be expected. This is complemented by the
observation of the behavior of other organisms, for instance, parents. All this
leads to a collection of knowledge for success, which again limits the
principal multiplicity of the environment for the organism in question. This
results in a direction to the gathering of knowledge, successful knowledge,
which means an approach to “representation,” to reflection of the environment
within the organism. In the case of human beings a principally new situation
arises. Their self‑activity is action in, and shaping of, the
environment. With this, the mere gathering of experiences turns into the
recognition of causality, of essential correlations (a post hoc [after
this] turns into propter hoc [because of this]). This is the basis of
law-governed cognition. It all takes place in a social connection. It is bound
up with speech, which creates an entirely new form of transmission, social
transmission, based on language passed on through education. All this makes
possible not merely a reflection theory that was already an enormous
philosophical achievement at the time of Democritus, but a reflection theory
that is appropriate to today’s level of knowledge.
Construction
of terms and philosophical constructivism
I have already mentioned the extensive
interest in the conception of philosophical constructivism, and also have
touched on some of its versions. One aspect that I neglected is the effect of
the “Copernican revolution” initiated by Kant. Until then, epistemology assumed
that our perception is directly of the object; Kant replied that we only
“constitute” the object by means of certain mental instruments that we possess
a priori—ideas of space and time, causality, categories, and so on—which
implies that we do not perceive the object in its objective being. This view
implies that all our perceptional efforts in principle cannot be detached from
mental constructions like terms, models, hypotheses, and theories. If we
correctly combine this with the thesis that perception, as well as any other
kind of human activity, is practical activity and arises only in connection
with practice, we come to the conclusion that our cognition is actually a form
of construing reality, and not merely its illustration or reflection.
Indeed a direct path to objective reality
is impossible for us. We always put material or mental instruments of
production between reality and ourselves. Not all representatives of this
conception want to do without “reality,” even if they have cut off the direct
way to it. They build it up again in their consciousness and call this a
conception of internal realism. Some use a spongy word that seems to be
a term without being one. They speak of Lebenswelt (“lifeworld” or
“lifeworld reality,” or simply just “life” or “reality”). This cannot be the
objective reality that exists outside of consciousness and independently of it,
because the way to it on the basis of this conception remains a secret.
As a consequence of this ambiguous basic
concept, self-deception cannot always be excluded if, while using the word life
or reality one thinks of something material, and while using the word
“practice,” one thinks of material, productive practice. In any case, social
reality in historical materialism means something else. It means material and
social production by humans in their exchange with the world of nature outside
themselves.
Followers of constructivism reply to
Marxists, in part justly, that they would equate with objective reality those
instruments of thought, such as terms, models, and theories, that we create for
research to “constitute” the “objects” of research.
I think that we have to hold a serious
theoretical debate on this. For if it were not true that we are dealing with
the dialectics of subject and object when we place instruments between us and
objective reality, we would end up with either a totally subjective idealism or
a mechanical materialism.
A starting point for such discussion is the
insights that are shared with Marxist philosophy: all our material or mental
activities are bound with means of a material or mental character that we place
between ourselves and the objects of our actions. In our mental activity, we
deal with terms, models, hypotheses, and theories. We create them in order to
make the things we want to act upon easier or even possible to deal with, to
make them comprehensible, to make them free from disturbing additions, that is,
under idealized conditions to make them ready for being investigated by us, for
example, by experiment. Thus everything we do involves the construction of
material or mental tools. This construing and this dependence of our knowledge
on such construing is acknowledged by these other schools. The only problem is
that they remain in this sector. The reason often given for this is the
so-called epistemological paradox. According to this paradox, when a comparison
is made between a nonmental material thing and its mental representation, we
are never able to leave the mental sector, so that we are never able to prove
that the thing and the illustration correspond to each other. In the best case,
the entirety of such mental constructions is recognized as determined by our
culture, by our “lifeworld,” by the “lifeworld conditions.” But this leads to
many questions: What are, in this case, life, culture, lifeworld, and lifeworld
reality? Where do they come from? How did they become the way they are? What is
the basis of their origin and their development? Varying a famous question from
Kant, we could ask: What do the conditions for the possibility of such
construing consist of? This is the point at which the principal philosophical
analysis, the basic clarification, would have to begin.
Some
philosophical problems arising from developments in physics
In the dispute between materialism and
idealism (in its theoretical and anthropomorphic religious appearance), if I
see it correctly, three major questions occur. At least two of these questions
have found important new answers, which undermine the basic positions of
idealism. I am referring to (1) the question of the finiteness or infiniteness
of the universe in time and space, (2) the origin of life, and (3) the origin
of the mind.
If we consider the recent results of
science, idealism has lost ground, to express it cautiously. Also in regard to
the question of the derivation of the mental from the nonmental, important new
research material has been gathered, even if this question has not been
entirely solved; yet we also must ask if a complete solution will really be
possible. The work of the Argentinian materialist philosopher Mario Bunge on
the mind-body problem contains, in my opinion, essential plausible results
(1980).
Whether this state of affairs is helpful
for materialism depends on whether philosophy can really be divided into the
two fundamental lines: materialism and idealism. There are only a few
exceptions that are excluded from this division, because they presuppose in a
dualistic manner two basic kinds of objects, one material and the other mental.
But even here we find within the concretely worked-out system tendencies in
which one or the other of these dominate, so that we indeed are not permitted
to characterize such a system as clearly either materialism or idealism, but still
see that within the system one or other of the two fundamental lines triumphs.
Lenin, referring to certain parts of Hegel’s great Logic, once noted
that this most idealistic work can in large parts be read like a materialist
work. And Kant’s epistemology is, as Lenin also noted, materialist with the
assumption of the thing-in-itself, but idealistic in its conditions for
the possibility of establishing what it is?
The developments in natural science
described here have led to extensive and fundamental philosophical debates. The
theory of relativity led to questioning of classical mechanics, and its
treatment of space and time. Far-reaching effects came from quantum theory. The
development of and debates over quantum theory are of great philosophical importance
in many ways. The mechanistic-materialist view of the world that most
scientists had accepted unconsciously or consciously, and the classical physics
coupled with it, were in contradiction to the new physical discoveries. The
evolution theories of thermodynamics and biology seemed to demonstrate a basic
contradiction between living and inanimate matter. Developments in biology also
led to fundamental philosophical discussions. Controversial conceptional
discussions in philosophy followed these scientific developments.
The reality
problem
Natural processes, and nature itself, seem
unproblematic to the so-called normal faculty of cognition in the sense that
nature, with the laws and forces governing it, in its spatial and temporal
existence, is accessible to cognition. On this basis, a more or less conclusive
and scientifically founded view of the world arose in correspondence with the
assumptions of classical physics. Only at its extremes—down “below” in the
microuniverse, and up “high” or “outward” in the universe—did it need further
development, further perfection. Our common sense, using ordinary language,
seemed adequate to give us a description of this world in a coherent way. This
so-called normal attitude toward perceiving nature presupposes that our ability
of cognition directly interacts with nature and directly procures knowledge
about nature for us.
This is not the case. Before World War I,
when scientists tried to get on the track of the atom, many important
conditions were lacking for the fulfillment of this task. Rutherford knew that
within the atom there must be a nucleus and electrons. Therefore he tried to
approach the unknown by imagining that the atom could be formed similar to the
solar system. Instead of the atom, which was not yet accessible to him, he used
as a model[iii] what was already known in order
to consider what was unknown. In subsequent work with this model, in improving
it, in the attempt to remove incompatibilities between the model and the actual
atom, scientists used not only current knowledge of the atom, but went far
beyond what we began with, by assuming quantum physics at the outset. The new
world picture built up in this way also had to be most accurate scientifically
to serve highly specialized fields. (Strictly speaking, this took place in part
earlier; one can go back to the previous work in mathematics by Riemann.) This
was more accurate and specialized than what we deal with in everyday language.
In the microphysical world, we encounter objects that we describe partly with
concepts from the macrophysical world, so that the question of the
interconnection between both domains arises. These microphysical objects,
however, have a real existence even though they have properties that cannot be
described in terms of macrophysical concepts.
On 12 March 1895, Engels wrote a letter to
Conrad Schmidt in which he discussed the relation of knowledge of the world in
terms of concepts created by us to the objective reality itself. Engels wrote
in part:
The reproaches you make against the law of
value apply to all concepts, regarded from the standpoint of reality.
The identity of thought and being, to express myself in Hegelian fashion,
everywhere coincides with your example of the circle and the polygon. Or the
two of them, the concept of a thing and its reality, run side by side like two
asymptotes, always approaching each other yet never meeting. This difference
between the two is the very difference which prevents the concept from being
directly and immediately reality and reality from being immediately its own
concept. But although a concept has the essential nature of a concept and
cannot therefore prima facie directly coincide with reality, from which
it must first be abstracted, it is still something more than a fiction, unless
you are going to declare all the results of thought fictions because reality
has to go a long way round before it corresponds to them, and even then only
corresponds to them with asymptotic approximation . . . .
Or are the concepts which prevail in the
natural sciences fictions because they by no means always coincide with
reality? From the moment we accept the theory of evolution all our concepts of
organic life correspond only approximately to reality. Otherwise there would be
no change: on the day when concepts and reality completely coincide in the
organic world development comes to an end. The concept fish includes a life in
water and breathing through gills: how are you going to get from fish to
amphibian without breaking through this concept? And it has been broken
through. (1942, 527, 530)
In material production, we place
instruments between ourselves and nature. From Hegel comes the designation of
these instruments as means, as the means between us and nature, as our mediated
effect on nature. Analogous with this is the widely used concept of means of
thought. For example, Brownian motion or the splitting of the atom can be
simulated by means of models in order to understand them better, to approach
the real object in this way. Yet the atoms are not only split in the model, but
also in reality. We can use models in experiments. In some fields we are only
able to work with models. But the real object of microphysics is the
microobject, even if it can only be examined by means of models. The statement
that something is a model does not yet define its epistemological nature. The
model is inserted between subject and object; it is elaborated; the results of
this elaboration are then transcribed. The question is how far can this
procedure be carried on. The essence of an object of cognition is not embraced
by the model. The question is to what extent are the means of cognition and the
object of cognition related to each other, to what extent is knowledge gained,
do the model and the modeled object correspond to each other? Models are
supposed to mediate between our knowledge and nature, to help us in the same
way as in material production, to come to new “products,” new knowledge, in
intellectual production.
This actually does not mean that we do not
know anything about nature itself; that we cannot come to know it. The problem
of reality is posed. Of course it could not be posed if the models of which are
speaking were like that, for example, of a miniature railway that originally
corresponded to a real railway, but only in miniature. But this miniature
railway just models the known, copying it as exactly as possible. The
previously mentioned models of science indeed are also constructed in analogy
to known things, but do not copy the object to which they refer, since it is
not yet known with the same precision (except for some unusual cases). The task
here is to provide an increasingly exact understanding of something still
unknown. On the other hand, would it be possible argue the matter if the problem
of reality were a closed book, or only a closed book?
Thus the problem of reality exists in two
aspects, since there is no thought that is detached from reality and since we
do not know with certainty if our thinking corresponds to reality.
Two major groups of philosophical positions
should be mentioned, a realist one and a positivist one. The difference between
them concerns the understanding of the real itself. For the group of
positivism, the real consists of what we consider as the observed (of course,
by experimental investigation using scientific/technical apparatuses), whereas
realism assumes that not only what is observed exists, but that there is, or
can be, something more essential than that.
In both groups we find variations. Within
realism. we find variations concerning the question of what should be
considered real. For materialism, it is not possible that material nature is
arises from the immaterial, since it exists independently of our consciousness.
For critical realism, the real is ultimately dependent on spirit (from
God, or an objective, absolute idea; thus it is an objective idealism).[iv] For internal realism the
real is the material of our mental processes, which amounts to a subjective
idealism.
Within positivism we find varying positions
about what the observed elements consist of. After all, they always are
attributed to the epistemological subject. Within so-called Machism
(empirio-criticism), they are understood as sense data; in the versions of
linguistic analysis, as subjectively judged forms of speech; in logical
empiricism, as logical structures detached from the real.
The question discussed up to this point
primarily concerns whether outside the world of our thoughts, another world
still exists and what is it like. Moreover, we have the question about what
mental activities are needed to open up this world to our cognition. We are
concerned here with the epistemological question, in distinction to the
ontological one.
Reality forced the makers of models, the
scientists, to change their model if they wanted to find out what was real, and
during the history of science, again and again, models that had come into
contradiction with reality have had to be abandoned or modified. But how could
something have a compelling effect if it did not exist? Thus we are dealing
with model builders, models, and reality in a three-sided relationship, with
correlations among them, with the activity produced by the constructor and
mediated by the model aimed at reality. The constructor, mediated by the model,
meets with the resistance of reality and is thus forced to change the model in
order to gain more exact knowledge about reality. As a result, a model having
proved to be useful cannot be entirely free from the correspondence, the
resemblance, the copy, the representation of what has been modeled, that is,
reality. Thus it contains the subjective as well as the objective.
Several positions also emerge in regard to
the subject and the process of cognition. Here too, we can divide them into two
major groups, one which affirms cognition and one which (in varying degrees)
denies cognition.
We cannot say that every kind of realism
includes the affirmation of cognition. Critical realism can accept cognition
only within certain boundaries, because the objective spiritual being creating
reality principally remains inaccessible to cognition, and in the best case can
be characterized by a series of negations (as not mortal or immortal,
for instance), thus indefinable.
Internal realism—and we must ask if it deserves
this name since, after all, it reduces reality to the world of our
thoughts!—allows in the best case, a hypothetical outside world, but denies its
perceptibility, as Kant does with his epistemology.
Human beings have a direct access to
nature, namely the nature of their own bodies, since they themselves are also
part of nature. Elementary life activity takes place by direct and indirect
material exchange with nature and within nature. Human access to nature is
possible on the basis of those physical and intellectual tools created by
humans. These tools are used only to accomplish the purpose intended. The
activity aims at, or corresponds to, that part of nature that is supposed to be
influenced by the mediating tools. To express it another way: In the course of
humanity’s historical and social processes, “references” have congealed and are
thus saved. The intellectual tools indeed do not exist outside of
consciousness. Thus they differ from the material ones, but still represent
something objectified in the sphere of the mental. Thanks to speech and
societal processes, consciousness includes the accumulated “references” of
nature. In a mediated way we therefore possess knowledge of nature itself.
These intellectual means enable us to transmit such knowledge, so that it is
proper to distinguish, but not to tear apart, the work of the natural sciences
and epistemology. This process of acquiring knowledge always occurs in a social
context. There is no production “in itself”—it is always socially determined
production. Therefore the material and intellectual tools are always socially
influenced. As a consequence, work in the natural sciences includes its models,
idealizations, and so on; it is influenced by society. Insofar as social
influences necessarily contain a connection to group interests, work in the
natural sciences has roots in nonscientific conditions, which, at the same time
provide the orientation for scientific work. Also by reason of this, a strict
division between natural and social sciences cannot be maintained. From all
this it follows that we can receive deeper knowledge about nature “in itself”
not only through philosophy, but also through the work of natural sciences.
The problem of
law
The history of physics and its influence of
philosophy has led to a better understanding of determinism, in which cause and
law are the same. With great success, this understanding allowed the assumption
that a body could be idealized as a point and that its states of motion could
be described exactly if its position and momentum at a given time were known.
With this information, it would also be possible to calculate precisely the
further course of motion of this moving body.
The understanding of causality became
identical with this comprehension of natural laws. This corresponded to our
experiences billions of times, and led in our consciousness to the opinion that
there was a necessary causal connection between these conditions, so that an
interruption of this causality (by chance) seemed impossible. This kind of
causality, this inevitable necessary connection between cause and effect, was
considered by Kant as a necessity of thought. The consequence for philosophy
and the natural sciences was the assumption that causality was exactly the same
as cause and effect. From this it would be possible to derive an exact
prediction of the behavior of objects. In the nineteenth century, Engels,
following Hegel, already had commented with mockery on the mechanistic
character of this kind of causality conception. Lenin, following Hegel, writes
that cause and effect “are merely moments of universal reciprocal dependence of
universal connection” of events, “merely links in the chain of development of
matter,” and that this “interconnection” is “only one-sidedly, fragmentarily,
and incompletely expressed by causality” (1961, 159). When physics advanced to
the microphysical sphere, problems arose. In the case of large objects, it
makes sense to treat such an object for certain purposes like a point. But in
reality they are not isolated, indivisible, individual objects, but complexes
of objects, of atoms and molecules, for instance. Among them correlations
exist; they form systems, entities, and the laws resulting from this are not
observed if this complex object is only seen as a single point.
This was changed when the observation of
the interior of such a system began. But difficulties arose from the
circumstance that the correlations of the elements of such a system again were
dealt with only by shifting the former way of thinking into the interior of the
system: so the elements now appeared as indistinguishable, similar individuals
correlated to each other as in classical physics.
Even before the new problems arose in
physics, we were forced to treat wave phenomena within the framework of
corpuscular classical mechanics. Then wave mechanics was born. So two kinds of
mechanics coexisted, corpuscular mechanics and wave mechanics. But the
microphysical objects display both wave and corpuscular qualities. They are not
identical “points.” Their behavior as a whole is influenced by chance.
Therefore another kind of law is necessary.
Laws are a special case of universal
interaction. Interaction makes the derivation of laws possible. The conceptions
of causality and law thus developed historically. The conception of law in
classical physics is based on strict continuity: the link between the causing
force and resulting effect cannot be interrupted at any point. But Planck’s
quantum of action cannot be arbitrarily small, which does not allow continuity
in microphysical processes, so that we find “quantum leaps,” that is,
interruptions of continuity in these processes. The conditions for classical
causality therefore do not exist here. Strictly seen, all physical occurrences
are based on such quantized foundations. Objective reality, after all,
possesses a quantized nature, with all its consequences, especially the
consequence of uncertainty. So here a conception of law is necessary other than
that in macrophysics.
The objects of macrophysics are ensembles
of microobjects. So the macrophysical laws after all must have roots in
microphysical reality. They are borderline cases of microphysical laws just as
Euclid’s geometry is a borderline case of the geometry necessary in relativity theory.
We can neglect this in common practice because microphysical effects do not
simply sum up, but are partially equalized in processes involving innumerable
microparticles, so that laws become possible for the macrosystem that are not
just a summary of the laws of the particles entering into it. At the same time,
the peculiarities of microphysics contain the possibility of the accidental.
Accident is an objective correlation between different occurrences, a
correlation that does not result from the essential inner conditions of the
occurrences. Accident itself is not without a cause. So it is not absolutely
accidental. Otherwise it would not be possible to determine the quantity of
Planck’s quantum of action h; it would be an absolutely accidental quantity
on one day, and another on the next day! But accident includes different
possibilities, and each of them has its own necessities. In face of the
multitude of particles forming a complete system, multiple interactions and
correlations can develop that are not necessarily connected with the total
system. In self-organization processes, accident is even a determining factor
for the development of the system. At those turning‑points of the system
(the bifurcation‑points), where the system is faced with different
possibilities for its further development, the direction of development will be
decided by a process arising from its inner conditions, which, in reference to
the total system, nevertheless must be considered as accidental. In this way
accident creates necessity.
In discussing questions concerning the
problem of law, we met different types of laws, especially those that act
differently in the macrophysical and microphysical spheres. The macrophysical
laws represent strictly continuous relations between objects and causing
forces, and are called dynamic laws (from dynamis, meaning force). They
allow only one possibility of how a law is realized. They do not involve
accident. Their corpuscular “point” character is conveyed by treatment of the
objects as individual objects, whereas the laws of microphysics act in a
collective way.
This is demonstrated by a special quality
of the microphysical laws: they have a statistical character. Statistical laws
in microphysics have a different nature from laws in classical physics. And
they have a totally different character from the classical causal laws. A
complicated dialectics of accident and law can be found here. I shall
demonstrate this with an example that does not deal with the type of
probability used by quantum theory, but gives an idea of the set of problems
encountered. If we throw dice thousands of times, we find that each of the
faces with one to six dots occurs about a sixth of the time. We can predict
this statistically, but not the result of a single throw. And if we repeat the
throwing of dice some thousands of times, we can also predict the relative
frequency of the results, but not the result of a single toss at a given time;
we also cannot assume that a second series of throws would reproduce the same
sequence of individual throws.
We find statistical characteristics in both
classical and quantum physics, but in different ways, so that we are speaking
about a primary and secondary form of statistics. The difference is as follows:
In classical physics (for instance in thermodynamics), statistics is used
because of the multitude of objects involved (such as molecules of a gas).
Single particles can no longer be considered as being in a clearly arranged
order, so that in principle, we cannot examine their individual behavior. In
quantum physics, the uncertainty principle rules out our even considering this
possibility.
The statistical laws of microphysics indeed
must regulate the behavior of the particles/waves forming the system, and
therefore: they must require a necessary, reproducible, essential (in regard to
the behavior of system as a whole) connection (dynamic aspect); they
must require that the behavior of the individual particles/waves have a random
character (stochastic aspect); they must require that the randomness in
the behavior of a single particle/wave reflect certain probabilities, which
means that the randomness is subject to the laws of probability and is not
causeless, not miraculous (probabilistic aspect).
Full acquaintance with the newly discovered
laws of the statistical kind was not without its difficulties, since it seemed
that it opened the door to agnosticism by its thesis of limited faculty for
human cognition. But this is not logical. If we realize that in nature laws
exist that force us to change from the causality conception of macrophysics,
not to conceptions of noncausality, but to another form of causality, then we
are not dealing with agnosticism, but with the possibility of cognition!
Limits in human cognitive abilities are not
the reason for applying stochastic laws; neither are these laws just to be
accepted temporarily until they can be replaced by classical causal laws. The
difficulty is that the old conception of law is linked to a certain
interpretation of causality. If it turns out that in the microphysical sphere
such simple causality does not exist, the pattern of classical laws itself
comes into question (in this sphere). Then it is not possible—on the basis of
the laws of nature and not because of limits in human cognitive faculty—to make
compelling predictions by means of stochastic laws that refer to a particular
case of subatomic behavior. It belongs to the essence of stochastic laws that
also the improbable can take place, so that our knowledge of stochastic laws
may become more and more exact, without, however, allowing compelling simple
causal explanations of the older kind.
It is obvious that this new conception of
causality and laws can also have consequences for social laws.
Some final
remarks
In examining the importance to materialist
philosophy of the natural science theories discussed here, I have tried to seek
out aspects that they have in common and any connection among them, to see if
they possess something like an “inner logic.”
These theories and hypotheses all examine
occurrences outside and independent of our consciousness. Deliberately or not,
the theorists working on these questions assume materialist positions. All of
them not only examine the motion, but also developments of the respective
spheres of objects. But the development processes on one level proceed to those
on another, higher one. So we are not dealing with a collection of examples of
development, but with a system of development that reaches from the “big bang”
to the origin and evolution of living matter. This is a confirmation of the
thesis that all spheres of objective reality are exposed to motion and
development: in the words of Engels in the 1870s, “motion is the mode of
existence of matter” (1987, 55). This objective reality forms a coherent
entity. In it we find dynamic relations, in which the elements change, having
their own motions. We find this, starting with the smallest elements of matter
up to the farthest and biggest cosmic objects, and also in their internal structure.
Some common characteristics appear that occur again and again within these
dynamic processes, from motion of a physical nature to systems of social life.
Therefore it is possible to point out these common characteristics from the
totality of theories and hypotheses analyzing these spheres, and in this way
approach a more profound understanding of the real processes of matter.
If the objective common characteristics of
the developmental processes are characterized as objective dialectics,
the theoretical generalizations should be called subjective dialectics.
Thus it would be philosophy for the purpose of intellectual grasping,
generalizing, and interpreting the knowledge that the specialized sciences have
ascertained about their objects. All these processes result from the
relationships between different forces that as a rule are complementary as well
as mutually exclusive, The theories of self-organization, of autopoiesis, of
catastrophes (free from their exaggerations and unjust overstatements), the new
view of biological evolution—in brief, the transition from the primacy of outer
effective factors to the inner ones—are not only significant steps for the
explanation of new occurrences, but also for the clarification of their origin,
a result of the activity of internal contrary forces or conditions, which again
means that we find a genuine dialectic of problems and answers.
The two aspects of the second law of
thermodynamics, the hypothesis of a universe oscillating between expansion and
contraction, the efforts to comprehend the nature of subatomic particles with
conceptions like that of complementarity, the contradictory relation of dynamic
and stochastic laws, and also the contradiction between relativity and quantum
theory, cannot be appropriately combined with philosophies of a nondialectical
and nonmaterialist kind. We find further developmental stages of dialectical
contradictions in the internal relations of forces in galaxies, the planetary
system, and the structure of atoms, all of which have their inner coherence
guaranteed by the entity of forces contradictory to each other. The discussed
theories and hypotheses, in their own special fields, give answers to the
question about why and in what way the emergence of the new takes place (without
something new emerging there is no development), and about which laws lead in a
particular direction (without this there would no development). They
substantiate the possibility and the necessity of suddenly occurring
innovations. They show that evolution takes place even within the most
seemingly motionless parts of nature.
As a rule, the steps for the development of
the new and the direction of development that follow from the theories and
hypotheses are connected with suddenly occurring breaks, phase changes, etc.
The emergence of the new includes breaking with the former as well as keeping
linked to it, the latter already results from the conservation laws. If during
the emergence of the new a breaking of symmetries occurs in some sector, the
conservation laws produce a compensation in another sector. The relation
between these two processes is to be examined. Prigogine’s interpretation that
self-organization is not possible without the export of entropy can be used as
an example.
If at a bifurcation point during a process
of self-organization, a break with the former state takes place, the transition
from a continuous to a discontinuous mode of observation with an appropriate
mathematics becomes necessary. If we assume that nowhere do we find plain continuity
and stability, that everything is in motion, and that motion itself after all
takes place in a quantized mode, the mathematical method must integrate breaks
and discontinuity. We find such mathematics in the conception of fractals. The
conceptions of self-organization, the conceptions that assign a determining
role to the activity of inner factors instead of outer, are new scientific
affirmations of the old dialectical theses, as well as the conceptions of the
general connection of all things and appearances. That the clarification of
life’s origin supplies materialism with strong arguments is certainly obvious.
As a whole, the position of practical
negation of any postulated human cognitive limits, which also characterizes the
new science, as well as the application of the criterion of practice as the
ultimate instrument of verification (and the intensive application of
induction), all confirm materialism.
