Chapter XVI
A Philosophical Postlude
It is both interesting and significant that the traditional
home of college courses on Space and Time is the Philosophy
Department, not the Scientific School. In order to appreciate to the full
extent what a strange situation this actually is, we might compare the
task of science in systematizing our knowledge of the universe to some
physical construction projectthe construction of a building, let
us say. Before a building can be started, there are many things to be
done; there has to be a decision to build, a site has to be selected,
financing must be arranged, and so on, all of which are necessary, yet
not, strictly speaking, part of the actual building construction. These
items are analogous to the normal tasks of the philosophers in connection
with science. It is their job to take care of the preliminaries, which
precede the actual construction of the framework of physical theory by
the scientists.
But space and time do not belong in this category at
all. In terms of the building analogy, they correspond to the bricks of
which the building is to be constructed. They are essential elements in
the physical structure of the universe, the study of which constitutes
the primary task of science, and they cannot legitimately be relegated
to any other discipline, no matter how closely related. In leaving the
foundations of their theoretical structure to the philosophers, scientists
are putting themselves in the same position in which engineers would be
placed if they left the construction of the foundations of their structures
to the financiers.
The truth is, of course, that space and time have not
been left to the philosophers because of any feeling on the part of scientists
that they belong in the Philosophy Department. Science has simply
been at a loss to know what to do with them, because the available knowledge
as to their nature and properties has been too meager and too uncertain
to permit treating them by normal scientific methods. The philosophers
have therefore acquired these subjects by default, not because they are
non-scientific or meta-scientific, but because they are hard to pin down
specifically. Space and time are scientific de jure(According to law),
but in present-day practice they are philosophical de facto. One
of the accomplishments of the Reciprocal System has been to bring space
and time back into science where they belong. As pointed out in connection
with the cosmic ray discussion, a very important advantage of a complete
theoretical system of this kind is that it can be verified in its entirety
by tests carried out in the areas accessible to accurate observation,
and after this is done, its application can be extended to relatively
unknown regions with the assurance that its conclusions are equally valid
in these regions. Thus we can determine exactly what roles space and time
play in the theoretical RS universe and since we have established the
identity of this universe and the observed physical universe, we then
know that these are also the roles of space and time in the physical universe.
What are space and time is an age-old question that has produced
an amazing variety of answers, few of which are even vaguely scientific.
What are time and space? They are the names for ways
of conducting certain measurements. (Whitehead)130
Time has been interpreted in an almost infinite variety
of ways and no one single statement can do more than picture it from
one point of view. (Merriam)131
The universe changes, and time is a process that brings
new out of old. (Schlegel)132
A physicist nowadays thinks of space as a collection
of relations of a special kind between objects. (Thomson)133
The idea of time in its most primitive form is probably
the recognition of an order of sequence in our states of consciousness.
(Maxwell)134
In recent science time is treated as an additional
dimension of space. (Hering)135
Space-Time is the stuff of which matter and all things
are specifications. (Alexander)136
Time is the independent variable in the laws
of mechanics. This is the very best definition that can be given
of time. (Margenau)137
The long-standing conflict between the supporters of
the absolute and relational theories of space and time is an outgrowth
of this uncertainty as to the true nature of these entities. Whether space
and time are logically prior to events or are determined by events has
been a bone of contention for more than two thousand years, but now that
the Reciprocal System gives us a definite and unequivocal answer to the
basic question, neither of these theories can be accepted in its entirety.
Space and time in the RS universe are the two reciprocal aspects of motion.
But events as the term is customarily used in this context,
are motions of one kind or another. Space and time, then, are neither
relational, in the sense of being determined by events, nor absolute,
as defined by Newton. There is a general framework of the universe, an
extension space, generated by translational motion, which is essentially
equivalent to Newtons absolute space, but other types of motion
also have spatial aspects, and extension space is therefore only one phase
of space in general. The absolute and relational concepts over which the
long argument has raged are simply inadequate to comprehend the full range
of time and space.
The question as to whether space and time are finite
or infinite is another, which previously existing theories have been unable
to answer conclusively. The existence of zero space and zero time is generally
conceded and no controversy has ever developed over these concepts comparable
to that which has raged over the question as to the existence of infinite
space or time, but the development of the Reciprocal System now shows
that the two are simply different aspects of the same thing. Infinite
space is equivalent to zero time and vice versa. To most scientists, the
ability of an object to remain stationary in space, relatively if not
absolutely, seems altogether logical, yet the new theoretical system says
that this involves infinite time; that is, no motion at all is equivalent
to taking infinite time to move one unit in space. In the new system all
other manifestations of infinite space and time have essentially this
same character.
It should be noted, however, that whether the universe
is finite or infinite in extent is an altogether different question.
Undisplaced space-time is the physical equivalent of nothing at all, and
when we speak of the universe we normally refer not to space-time as such,
but to the aggregate of those space-time displacements which manifest
themselves primarily as matter or c-matter. As we have seen, the existence
of matter is limited in time; that is, the giant galaxies into which the
oldest matter in the material sector collects ultimately explode and initiate
a process, which converts the old matter into new cosmic matter. The existence
of cosmic matter is similarly limited in space. We must therefore conclude
that the universe, as herein defined, is finite in extent, even though
the space and time in which it exists and of which it is composed are,
in a sense, infinite.
As brought out in Chapter XIV, the new findings also
indicate that the universe is in a steady state rather than undergoing
any one-way process of evolution. A special word of caution is appropriate
at this point. Decision between the evolutionary and continuous cosmological
theories does not have any implications at all with reference to the question
as to whether or not an act of creation has taken place. There has been
a tendency on the part of the theologians and scientists with strong religious
beliefs to favor an evolutionary hypothesis on the ground that this implies
a beginning of the universe, which can be correlated with creation, whereas
a hypothesis that pictures the universe as without beginning and without
end seems to conflict with the creation doctrine. The truth is, however,
that neither hypothesis has any bearing on the creation issue one way
or the other. If the present epoch of the universe originated with an
explosion as postulated by Lemaitre, this is still not a beginning; the
problem of the origin of the material, which exploded, still remains.
The evolutionary hypothesis does not, in any way, resolve the creation
problem.
Neither does the steady state hypothesis complicate it.
There is no visible reason why the creation of a universe that remains
in a steady state after it is created should be any less plausible than
the creation of an evolutionary universe. In some respects the findings
of this work actually simplify the creation issue. The hotly debated question
as to what was happening before the creation, for instance, no
longer has any significance, since it is evident that, if the creation
occurred, it was space-time itself that was created, as St. Augustine
contended centuries ago, and hence the concept of before did
not acquire any meaning until the creation took place.
What the Reciprocal System has done with respect to the
issues that have been discussed thus far in this chapter (excluding the
question of creation, which is outside the realm of science) is to remove
them from philosophy, put them back into science where they belong de
jure, and fit them into their proper places in the definite and specific
theoretical framework that has been constructed for the universe
as a whole. But the clarification that has been accomplished in this area
where philosophy and science have to some degree overlapped is not all
that the new development has accomplished of interest to philosophers.
Another thing that it has done is to throw some additional light on the
application of philosophy to science.
One of the noteworthy facts about modern science is that
some of its most spectacular and widely hailed results have been achieved
by the use of methods or concepts, which have been opposed, or at least
disapproved, by the philosophers. (For present purposes we are excluding
from this category those individuals whose aim is to derive a philosophy
from science rather than to apply philosophical principles to science.)
The following statements bring out the nature of some of these differences
of opinion:
The divergences between physicists and philosophers
have become very clear recently. We have only to glance at the discussions
about space, time and causality connected with relativity and the quantum
theory to see this. (Frank)138
When we start postulating strange things about the
world, justifying our choice not by explaining the matter properly but
resorting to a mystique, we should beware. We know that our knowledge
and experience are limited, but that is not reason enough for our being
imposed on to accept formulas for interpreting successfull technical
inventions when the interpretation strains language and seems not to
make sense to us. (Watson)139
I believe that the conceptual structure of quantum
mechanics today is as unhealthy as the conceptual structure of the calculus
was at the time Berkeleys famous criticism was issued. (Putnam)140
There is no reason whatever why a future atomic theory
should not return to a more classical outlook without contradicting
actual experiment, or without leaving out facts already known and accounted
for by wave mechanics. (Feyerabend)141
The conceptions introduced by Einstein must accordingly
be admired to the extent that they constitute a powerful physicomathematical
synthesis; but they must be rejected if given properly philosophical
meaning. (Marilain)142
The physicist has made his choice in rejecting as basically
incorrect the classical description of motion. The philosopher has not
always been willing to follow him. (Margenau)143
Primitive notions such as those of time and space .
. . always trouble the philosopher, who dislikes seeing elaborate structures
reared on shaky foundations. (Lindsay)144
Quantum physics, I submit, presents a strong case against
traditional logic. (Waismann)145 There is no convincing instance
of the alleged need to change the laws of logic in order to achieve
better conformity of theory and fact. (Feigl)146
The old conflict between absolute and relational space,
while still alive in philosophic discussions, is settled and dead in
science. (Margenau)147 What men of one generation are
pleased to regard as satisfactorily settled may be questioned by a succeeding
one so the philosopher is not disposed to accept the confidence of the
scientist with his enthusiasm. (Watson)148
The astounding thing about these conflicts between the
conclusions of the philosophers and those of the scientists is that in
every one of the instances cited, the findings of this present investigation
are that the philosophers are right, or partially so, and the scientists
are wrong. This does not imply that the philosophers are always
right when there is a conflict of this kind. The foregoing list is by
no means a complete catalog of such conflicts, nor is it necessarily true
that the opinions of the authors quoted are representative of the majority
opinion in the particular field; this is merely a sample collected somewhat
randomly from the literature of the two professions. But there is enough
evidence here to indicate that the broad general principles of philosophy,
in spite of their largely intuitive and unverifiable nature, provide more
reliable guidelines than many of the conclusions of present-day science.
However distasteful this conclusion may be to the scientific
profession, it is not entirely unprecedented. Heisenberg, who can hardly
be described as prejudiced against the scientific viewpoint, has are rived
at much the same conclusions with respect to the relative reliability
of the language forms of scientific usage as compared to those in common
use. In this connection he comments: The concepts of natural language,
vaguely defined as they are, seem to be more stable in the expansion of
knowledge than the precise terms of scientific language, derived as an
idealization from only limited groups of phenomena.149 The underlying principle is the
same in both cases: a vague, but essentially correct, formulation is more
reliable than a precise, but erroneous, formulation.
It does not follow that philosophy is inherently more
trustworthy than science. On the contrary, science has an important advantage
in that a reasonable degree of certainty attaches to many of its findings,
and the zone of certainty is continually growingindeed, the primary
objective of the present work is to contribute toward this result. Where
science can speak with certainty, it speaks authoritatively. The conflicts
such as those cited do not arise in this zone; they occur in those areas
where science is positive without being certain, areas, which are
particularly extensive in so-called modern science.
As Heisenberg points out in the statement just quoted,
scientific conclusions rest on a very narrow base; they are derived from
only limited groups of phenomena. It logically follows, therefore,
that an extraordinary degree of care ought to be taken in the critical
examination of these conclusions in order to make certain that they are
at least consistent with the limited number of facts which are available
for comparison before accepting them on anything more than a tentative
basis. Even this special attention to the verification process would not
entirely compensate for the inadequacy of the basic data, but it would
at least make a contribution toward that result. However, the modern scientist
rejects this view of the situation and takes the stand that his methods
and procedures are so powerfull that the conclusions, which he reaches,
are incontestable and should be exempt from the necessity of confirmation.
The following quotation from Margenau expresses this present-day viewpoint:
Though it may seem strange to the logician, scientists
are none too meticulous in their demands for sufficiency in the number
of validating instances.... Reliance upon the logical coherence of his
conceptions exempts the scientist from the need of exhaustive verification.
There is an important sense in which a theory is more than the class
of sentences it can generate, and the awareness of this transcendency
inclines scientists to unhesitating acceptance of a theory after it
has been subjected to a number of tests which are wholly inadequate
statistically.150
Just why the conceptions of the physical
scientist should be inherently more logically coherent than
those of anyone else is rather difficult to understand. The ancient jest
about the individual who does not have to prove that he is right
because he freely admits it seems to have here made its appearance
in all seriousness. The point that Margenau and his colleagues are overlooking
is that sound or coherent reasoning does not guarantee sound
conclusions; on the contrary, the better the reasoning process the more
certain it is to arrive at the wrong conclusions if, as in this instance,
it starts from the wrong premises. The revolutionary conclusions
of modern physics are wholly dependent on the premise that all possible
alternatives to these conclusions have been located, examined, and rejected.
As this present work demonstrates, this premise is altogether false. There
are other alternatives in every case, and the completely unexpected
nature of most of them is a graphic demonstration of the fact that the
scope of the human mind is still severely limited. No system of human
thought, scientific or otherwise, has yet reached the stage where it is
completely self-sufficient. It is not yet possible to be sure that all
aspects of any particular issue, or all alternative explanations of any
particular situation, have been covered, or that the chain of reasoning
that has been utilized is flawless.
The preceding pages are full of instances that confirm
the foregoing statements and illustrate the fallibility of scientific
conclusions. For hundreds of years scientists have been convinced that
gravitation must either be due to action at a distance or else must be
propagated through a medium, or the equivalent of a medium, at a finite
velocity. The most careful study of the situation by the most capable
men in the profession over a long period of time has failed to produce
any other plausible alternative, and this has been accepted as a clear
indication that no such alternative exists. But in all of this scientific
consideration of the problem it has been taken for granted that gravitation
is an action of one mass upon another, and the investigators have been
unable to rise far enough out of the traditional channels of thought to
realize that this is not necessarily true; that it is merely an assumption
suggested by the observed phenomena. By widening the horizons of
thought to take other possibilities into account this present development
has been able to produce a logical, consistent, and workable alternative
in this case where modern science has been positive that there was no
alternative.
Essentially the same thing has happened with respect
to the problem of explaining the constant velocity of light. Scientists
have been completely convinced that they have made a thorough-going
analysis of all conceivable alternatives,56 and have therefore concluded that
Relativity, which seems to be the most plausible of these conceivable
alternatives must be correct. Here again many of the things that
are taken for granted in the consideration of the problem are merely assumptions,
but the investigators have been unable to visualize the possibility that
one or more of these assumptions might be in error. As in the case of
gravitation, this work has taken a broader view of the situation and has
found that by so doing it becomes possible here, also, to discover a logical,
consistent, and workable alternative where present-day science is positive
that no alternative is conceivable.
Since these and the many other similar instances that
can be found in the preceding pages clearly demonstrate that the human
mind, be it scientific or non-scientific, has not yet reached the point
where it can safely assume that it has exhausted the possibilities in
any such investigation, it follows that the negative conclusions of
science are inherently unreliable. Statement of an established positive
principle in negative form is entirely acceptable. The statement
that a perpetual motion machine is impossible, for example, is actually
an expression of a firmly established conservation law. But when science
says that it is impossible in principle to assign both a definite position
and a definite momentum to a particle, or that it is impossible to detect
absolute velocity, or that it is impossible to find any causal relationship
leading to the radioactive disintegration of a particular atom, or makes
some other statement of this nature, it is making an assertion which rests
entirely on the premise that what scientists have not been able to do
cannot be done: an inferential claim to infallibility that is not only
completely unwarranted but highly presumptuous.
There is nothing particularly unusual about rationalizing
failure to solve a problem by advancing the contention that the problem
is insolubleevery schoolboy tries this technique when he meets his
first difficult arithmetic assignment. The astounding fact in this particular
case is that the scientific profession is not only getting away with this
preposterous excuse for failure to reach its objectives, but is also well
on the road to persuading (or browbeating) the philosophers into modifying
or eliminating the long-standing philosophical principles which so clearly
brand the most highly publicized conclusions of modern science as illogical
and untenable. The problem, says Hesse, has been to
make sense of the apparently paradoxical statements which physicists have
been led to make in formulating the new theories.151 In this strange situation, those
who cannot make sense of their theories, and find that these
theories cannot qualify as logical or reasonable, are attempting (and
to a considerable degree succeeding in the attempt) to force a redefinition
of logic and reason.
Even the originators and the strong supporters of these
modern theories freely admit that they strain credulity to the utmost
and border on the absurd. Heisenberg, for example, speaking of the Copenhagen
interpretation of quantum theory, says:
It was not a solution, which one could easily accept....
I repealed to myself again and again the question: Can nature possibly
be as absurd as it seemed to us in these atomic experiments?152
The present general acceptance of these Copenhagen doctrines
by the physicists does not mean that the logical situation has changed
in any way. The explanations, which they offer, are just as absurd as
Heisenberg found them originally, but the physicists simply feel that
they have no other choice. As James B. Conant puts it, they have
learned to live with a paradox that once seemed intolerable.153
The argument which is relied upon to support such inherently
implausible theories and to justify the contention that it is nature
that is absurd, rather than the products of the theorists, is always the
alleged lack of any alternative. There is no other way,88 as Einstein puts it. All through
the literature of modern science this same argument is repeated over and
over again. It echoes as a far Miliar refrain in the statements quoted
in the earlier pages. There was and there is now no alternative,70 asserts Millikan. There are
no physical laws to tell usand there cannot be,116 contends Bronowski. Physicists
have made a thorough-going analysis of all conceivable alternatives,56 reports Sherwin. The only
interpretation of newly discovered facts, says Bridgman, is that
nature is intrinsically and in its elements neither understandable nor
subject to law.15 There is no intelligible
alternative currently available, hence we must accept present-day
theories even though they are conceptually imperfect and riddled
with inconsistencies,30 Hanson tells us.
It cannot be denied that there is a certain amount of
force to this argument when it is used as Hanson is using it, not in support
of current theory per se, but as a reason for utilizing such theory pending
the possible development of something better. But no matter how it is
used, it is a very vulnerable argument, since it is immediately and utterly
demolished as soon as the allegedly non-existent alternative is produced.
The presentation of such alternatives in this work has therefore destroyed
the foundation of the argument in favor of accepting the conclusions of
modern physics, in spite of their numerous and serious shortcomings.
From this standpoint it is entirely irrelevant whether
or not the reader of the preceding pages is convinced by the case therein
presented and is willing to concede the validity of the new theoretical
system. The mere production of a logical and self-consistent alternative
automatically invalidates the contention that no such alternative
exists, and overturns all theories that rest upon such a contention. The
kind of a wholesale demolition of claims of this nature that has been
carried out in this work goes even farther; it demonstrates that any
contention that there are no more alternatives is unsound; that the human
race has not yet arrived at that degree of infallibility which would make
it legitimate to assert that all possible alternatives have already been
examined.
Philosophers already knew thisit is the kind of
a conclusion that is readily derived from philosophical considerationsand
it is unfortunate that they have not been more outspoken in their criticism
of scientific doctrines that justify the advocacy of irrational theories
on the ground that there is no intelligible alternative. Feyerabend
makes this comment:
Philosophers of science... have become rather tame
(or beat) and are much more prepared to change their ideas in accordance
with the latest discoveries of the historians, or the latest fashion
of the contemporary scientific enterprise. This is very regrettable,
indeed, for it considerably decreases the number of the rational critics
of the scientific enterprise.154
The findings of this present work now provide some strong
reinforcement for those who take their stand on sound logical and rational
principles. Here the great handicap of science, the very narrow factual
base on which each of its conclusions rests, a base derived from
only limited groups of phenomena, as Heisenberg puts it, is overcome
by the construction of a completely integrated theoretical structure which
has the support of an enormous number of positively known facts derived
from all types of physical phenomena. The Reciprocal System is thus far
better equipped than any of its predecessors to take issue with philosophical
principles should this be required but, as could safely be predicted from
elementary considerations based on the concept of a rational universe,
when science thus puts its own house in order there is no longer any point
at issue. The findings of the present development are completely in harmony
with both philosophy and common sense.
In every case where present-day science insists that
we must accept illogical, unreasonable, and paradoxical conclusions because
there are no alternatives, this work has produced sound, logical and consistent
alternatives. There is no longer any justification for the contention
that we must accept an incomprehensible wave-particle duality,
that we must abandon the concept of absolute magnitudes, that we
must give up the idea of causality, and so on. The position of
those philosophers who have always opposed the uncontrolled excursions
of science into realms of fantasy beyond the reach of sound philosophical
and common sense principles is thus fully vindicated. In retrospect, the
words of some of these individuals have a distinctly prophetic ring. Consider
the following from Maritain, for example:
Metaphysics... renders mathematical physics the essential
service of protecting it against distortions that would be almost inevitable
without it; above all against the harmful illusion that leads it to
regard itself as a philosophy of nature and to believe that things begin
to exist only when they are measured by our instruments.155
In view of the great amount of discussion, both in scientific
and in philosophical circles, about the issue of determinism, it may be
well to emphasize that the return to strict causality in the Reciprocal
System does not imply a deterministic universe. The two concepts are often
confused in current thought. As Lindsay says, There is some
disagreement among scientists about the concept of causality. Among many
it is essentially equivalent to the notion of determinism.156 But the statement that A causes
B does not include the assertion that all features of B are determined
by A. The latter is determinism; the former is causality.
This distinction is somewhat obscured in a universe composed
of thingsentities that are essentially permanent. Determinism,
in the Laplacian sense, visualizes the behavior of all entities in the
universe as analogous to the behavior of the molecules of a gaseous aggregate,
where it theoretically would be possible (assuming an isolated system)
to specify the conditions at any future time if the initial conditions
were given. But we do not live in a universe of permanent things;
we live in a universe of motion, and the existence, in this universe,
of transformation processes by which the various combinations of motion
that constitute the entities of the physical universe change their forms
and identities rules out determinism.
Causality can be maintained through a series of such
processes, but not determinism, as the properties of entity A are not
the same as those of the entity B into which it is transformed, and hence
directional specifications cannot be carried forward from one phase to
the next, nor is it always possible to specify what form the product
will take. The photon, for example, is transformed into thermal motion
when absorbed by matter. Later, that thermal motion is again transformed
into another photon of radiation. A complete causal chain is maintained.
The absorption of the photon causes a minute increase in the thermal motion
of the matter, and hence in its temperature. The increased temperature
then causes the radiation from this aggregate of matter to be speeded
up to the extent of emitting one additional photon. But the deterministic
connection is broken. The direction of the incident photon has no bearing
at all on the direction of the emitted photon, the latter being determined
entirely by probability considerations. The Reciprocal System introduces
a host of new transformation processes which operate in a similar mannertransformations
of one kind of a particle into another, transformations of matter into
radiation or kinetic energy, transformations of motion in space into motion
in time, and so onand each of these processes breaks the deterministic
relation, even though it maintains the causal connection.
Like the emission of a photon, the emission of an electron,
a radioactive particle, or some other unit, is always due to a specific
cause, but just as in the case of the photon, there is some aspect of
the emission process, which is indeterminate. The photon actually has
no direction of its own, because it has no independent motion (aside from
the vibratory motion that makes it a photon). The tansrational motion,
which we observe is supplied by the progression of space-time, and since
the progression, is scalar, the direction which the photon will take is
purely a matter of chance. Whether or not it will ultimately impinge on
some particular distant object is therefore a question of probability;
the original influence can cause emission but it cannot determine
where the photon goes.
This is a much different picture of the situation than
the one we get from modern physics, which denies the existence of specific
identifiable causes for events at the microphysical level. In the words
of Bridgman, Whenever he (the physicist) penetrates to the atomic or
electronic level in his analysis, he finds things acting in a way for
which he can assign no cause, for which he can never assign a cause,
and for which the concept of cause has no meaning, if Heisenbergs
principle is right. This means nothing more nor less than that the law
of cause and effect must be given up.157
However bravely the modern physicist may talk for publication,
this is not the kind of a situation that any believer in the rationality
of the universe as a whole can contemplate with equanimity, and Bridgman
reveals his own disquietude about the subject in the following rather
plaintive statement:
The physicist thus finds himself in a world from which the bottom has
dropped clean out; as he penetrates deeper and deeper it eludes him
and fades away by the highly unsports man like device of just becoming
meaningless. No refinement of measurement will avail to carry him beyond
the portals of this shadowy domain, which he cannot even mention without
logical inconsistency.158
The findings of this present work now give the scientist
an opportunity to escape from this awkward dilemma; they enable him to
maintain strict scientific conformity with the facts of observation while
remaining wholly within the bounds of logic and rationality. From a scientific
standpoint, the most significant thing about the new theoretical system
presented in this work, the Reciprocal System is that it is in agreement
with all positively known facts or, at least, is not inconsistent with
any of them. From a philosophical standpoint, its most significant feature
is that it is in harmony with nature; it does not picture nature as absurd,
or meaningless, or paradoxical. It defines a universe
that is logical, orderly, and rational, and that is readily understandable
in all of its details, if a reasonable effort is made to look at natural
processes as they actually exist, not in some artificial context imposed
by human preferences and prejudices.
