The Philosophical Test of the Revelations of Religious Experience
-With Einstein space is real, but relative
to the observer. He rejects the Newtonian concept of an absolute
space. The object observed is variable; it is relative to the observer;
its mass, shape, and size change as the observers position
and speed change. Movement and rest, too, are relative to the observer.
There is, therefore, no such thing as a self-subsistent materiality
of classical physics. It is, however, necessary here to guard against
a misunderstanding. The use of the word observer in
this connexion has misled Wildon Carr into the view that the theory
of Relativity inevitably leads to Monadistic Idealism. It is true
that according to the theory the shapes, sizes, and durations of
phenomena are not absolute. But as Professor Nunn points out, the
space-time frame does not depend on the observers mind; it
depends on the point of the material universe to which his body
is attached. In fact, the observer can be easily replaced
by a recording apparatus. Personally, I believe that the ultimate
character of Reality is spiritual: but in order to avoid a widespread
misunderstanding it is necessary to point out that Einsteins
theory, which, as a scientific theory, deals only with the structure
of things, throws no light on the ultimate nature of things which
possess that structure.
The philosophical value of the theory is twofold. First, it destroys,
not the objectivity of Nature, but the view of substance as simple
location in space - a view which led to materialism in Classical
Physics. Substance for modern Relativity-Physics is
not a persistent thing with variable states, but a system of interrelated
events. In Whiteheads presentation of the theory the notion
of matter is entirely replaced by the notion of organism.
Secondly, the theory makes space dependent on matter. The universe,
according to Einstein, is not a kind of island in an infinite space;
it is finite but boundless; beyond it there is no empty space. In
the absence of matter the universe would shrink to a point. Looking,
however, at the theory from the standpoint that I have taken in
these lectures, Einsteins Relativity presents one great difficulty,
i.e. the unreality of time. A theory which takes time to be a kind
of fourth dimension of space must, it seems, regard the future as
something already given, as indubitably fixed as the past. Time
as a free creative movement has no meaning for the theory. It does
not pass. Events do not happen; we simply meet them. It must not,
however, be forgotten that the theory neglects certain characteristics
of time as experienced by us; and it is not possible to say that
the nature of time is exhausted by the characteristics which the
theory does note in the interests of a systematic account of those
aspects of Nature which can be mathematically treated. Nor is it
possible for us laymen to understand what the real nature of Einsteins
time is.
It is obvious that Einsteins time is not Bergsons pure
duration. Nor can we regard it as serial time. Serial time is the
essence of causality as defined by Kant. The cause and its effect
are mutually so related that the former is chronologically prior
to the latter, so that if the former is not, the latter cannot be.
If mathematical time is serial time, then on the basis of the theory
it is possible, by a careful choice of the velocities of the observer
and the system in which a given set of events is happening, to make
the effect precede its cause. It appears to me that time regarded
as a fourth dimension of space really ceases to be time. A modern
Russian writer, Ouspensky, in his book called Tertium Organum, conceives
the fourth dimension to be the movement of a three-dimensional figure
in a direction not contained in itself. Just as the movement of
the point, the line and the surface in a direction not contained
in them gives us the ordinary three dimensions of space, in the
same way the movement of the three-dimensional figure in a direction
not contained in itself must give us the fourth dimension of space.
And since time is the distance separating events in order of succession
and binding them in different wholes, it is obviously a distance
lying in a direction not contained in the three-dimensional space.
As a new dimension this distance, separating events in the order
of succession, is incommensurable with the dimensions of three-dimensional
space, as a year is incommensurable with St. Petersburg. It is perpendicular
to all directions of three-dimensional space, and is not parallel
to any of them. Elsewhere in the same book Ouspensky describes our
time-sense as a misty space-sense and argues, on the basis of our
psychic constitution, that to one-, two- or three-dimensional beings
the higher dimension must always appear as succession in time.
This obviously means that what appears to us three-dimensional beings
as time is in reality an imperfectly sensed space-dimension which
in its own nature does not differ from the perfectly sensed dimensions
of Euclidean space. In other words, time is not a genuine creative
movement; and that what we call future events are not fresh happenings,
but things already given and located in an unknown space. Yet in
his search for a fresh direction, other than the three Euclidean
dimensions, Ouspensky needs a real serial time, i.e. a distance
separating events in the order of succession. Thus time which was
needed and consequently viewed as succession for the purposes of
one stage of the argument is quietly divested, at a later stage,
of its serial character and reduced to what does not differ in anything
from the other lines and dimensions of space. It is because of the
serial character of time that Ouspensky was able to regard it as
a genuinely new direction in space. If this characteristic is in
reality an illusion, how can it fulfil Ouspenskys requirements
of an original dimension?
Passing now to other levels of experience - life and consciousness.
Consciousness may be imagined as a deflection from life. Its function
is to provide a luminous point in order to enlighten the forward
rush of life. It is a case of tension, a state of self-concentration,
by means of which life manages to shut out all memories and associations
which have no bearing on a present action. It has no well-defined
fringes; it shrinks and expands as the occasion demands. To describe
it as an epiphenomenon of the processes of matter is to deny it
as an independent activity, and to deny it as an independent activity
is to deny the validity of all knowledge which is only a systematized
expression of consciousness. Thus consciousness is a variety of
the purely spiritual principle of life which is not a substance,
but an organizing principle, a specific mode of behaviour essentially
different to the behaviour of an externally worked machine. Since,
however, we cannot conceive of a purely spiritual energy, except
in association with a definite combination of sensible elements
through which it reveals itself, we are apt to take this combination
as the ultimate ground of spiritual energy. The discoveries of Newton
in the sphere of matter and those of Darwin in the sphere of Natural
History reveal a mechanism. All problems, it was believed, were
really the problems of physics. Energy and atoms, with the properties
self-existing in them, could explain everything including life,
thought, will, and feeling.
The concept of mechanism - a purely physical concept - claimed to
be the all-embracing explanation of Nature. And the battle for and
against mechanism is still being fiercely fought in the domain of
Biology. The question, then, is whether the passage to Reality through
the revelations of sense-perception necessarily leads to a view
of Reality essentially opposed to the view that religion takes of
its ultimate character. Is Natural Science finally committed to
materialism? There is no doubt that the theories of science constitute
trustworthy knowledge, because they are verifiable and enable us
to predict and control the events of Nature. But we must not forget
that what is called science is not a single systematic view of Reality.
It is a mass of sectional views of Reality - fragments of a total
experience which do not seem to fit together. Natural Science deals
with matter, with life, and with mind; but the moment you ask the
question how matter, life, and mind are mutually related, you begin
to see the sectional character of the various sciences that deal
with them and the inability of these sciences, taken singly, to
furnish a complete answer to your question. In fact, the various
natural sciences are like so many vultures falling on the dead body
of Nature, and each running away with a piece of its flesh. Nature
as the subject of science is a highly artificial affair, and this
artificiality is the result of that selective process to which science
must subject her in the interests of precision. The moment you put
the subject of science in the total of human experience it begins
to disclose a different character. Thus religion, which demands
the whole of Reality and for this reason must occupy a central place
in any synthesis of all the data of human experience, has no reason
to be afraid of any sectional views of Reality.
Natural Science is by nature sectional; it cannot, if it is true
to its own nature and function, set up its theory as a complete
view of Reality. The concepts we use in the organization of knowledge
are, therefore, sectional in character, and their application is
relative to the level of experience to which they are applied. The
concept of cause, for instance, the essential feature
of which is priority to the effect, is relative to the subject-matter
of physical science which studies one special kind of activity to
the exclusion of other forms of activity observed by others. When
we rise to the level of life and mind the concept of cause fails
us, and we stand in need of concepts of a different order of thought.
The action of living organisms, initiated and planned in view of
an end, is totally different to causal action. The subject-matter
of our inquiry, therefore, demands the concepts of end
and purpose, which act from within unlike the concept
of cause which is external to the effect and acts from without.
No doubt, there are aspects of the activity of a living organism
which it shares with other objects of Nature. In the observation
of these aspects the concepts of physics and chemistry would be
needed; but the behaviour of the organism is essentially a matter
of inheritance and incapable of sufficient explanation in terms
of molecular physics. However, the concept of mechanism has been
applied to life and we have to see how far the attempt has succeeded.
Unfortunately, I am not a biologist and must turn to biologists
themselves for support. After telling us that the main difference
between a living organism and a machine is that the former is self-maintaining
and self-reproducing, J.S. Haldane says:
It is thus evident that although we find within the living
body many phenomena which, so long as we do not look closely, can
be interpreted satisfactorily as physical and chemical mechanism,
there are side by side other phenomena [i.e. self-maintenance and
reproduction] for which the possibility of such interpretation seems
to be absent. The mechanists assume that the bodily mechanisms are
so constructed as to maintain, repair, and reproduce themselves.
In the long process of natural selection, mechanisms of this sort
have, they suggest, been evolved gradually.
Let us examine this hypothesis. When we state an event in
mechanical terms we state it as a necessary result of certain simple
properties of separate parts which interact in the event. . . .
The essence of the explanation or re-statement of the event is that
after due investigation we have assumed that the parts interacting
in the event have certain simple and definite properties, so that
they always react in the same way under the same conditions. For
a mechanical explanation the reacting parts must first be given.
Unless an arrangement of parts with definite properties is given,
it is meaningless to speak of mechanical explanation.
To postulate the existence of a self-producing or self-maintaining
mechanism is, thus, to postulate something to which no meaning can
be attached. Meaningless terms are sometimes used by physiologists;
but there is none so absolutely meaningless as the expression "mechanism
of reproduction". Any mechanism there may be in the parent
organism is absent in the process of reproduction, and must reconstitute
itself at each generation, since the parent organism is reproduced
from a mere tiny speck of its own body. There can be no mechanism
of reproduction. The idea of a mechanism which is constantly maintaining
or reproducing its own structure is self-contradictory. A mechanism
which reproduced itself would be a mechanism without parts, and,
therefore, not a mechanism
