Modern natural science regards Experience as the
only source for the investigation of truth. And not wrongly, to be
sure. Its area is the realm of outer, spatial things and temporal
processes. How should one be able to make anything out about an
object belonging to the outer world, without having gotten to know it
by means of sense-perception, that is, the only manner of coming in
contact with things spatial-temporal. First get to know the
object,
[see note 1]
and then theorize about it, so goes the
maxim asserted by modern science over against the speculative systems
of the philosophers of nature from the beginning of this century.
This principle is completely justified, but by an erroneous
conception, it has led science astray. The misunderstanding lies in
the character attributed by the inductive method, and by the
materialism and atomism issuing from it, to general concepts. For the
person of understanding, there can be no doubt that the current state
of natural science in its theoretical part is essentially influenced
by concepts as they have become dominant through Kant. If we want to
go into this relationship more closely, we must commence our
consideration with him. Kant limited the scope of Recognition to
Experience, because in the sensory material communicated by it, he
found the only possibility of filling in the concept-patterns, the
categories, inherent in our mental organization, by themselves quite
empty. For him, sensory content was the only form of such a
conceptual pattern. Thereby he had steered the world's judgment into
other courses. If, earlier, one had thought of concepts and laws as
belonging to the outer world, if one had ascribed to them objective
validity, now they seemed to be given merely by the nature of the
“I.” The outer world counted merely as raw material,
to be sure, yet as that which alone reality was to be ascribed to.
This standpoint was inherited from Kant by Inductive Science. It too
counts the material world as the only thing real; for it, concepts
and laws are justified only to the extent that they have that world as
their content and mediate the recognizing of it. It regards concepts
reaching beyond this realm as unreal. For it, general thoughts and
laws are mere abstractions, derived from the agreements experienced
in a series of observations. It knows mere subjective maxims,
generalizations, no concrete concepts bearing their validity in
themselves. This must be borne in mind if one wants to penetrate from
a lot of murky concepts circulating nowadays through to complete
clarity. One will first have to ask oneself: what then is
Experience, really, gained of this or that object? In works on the
philosophy of experience, one will search in vain for a
matter-of-fact, satisfying answer to this certainly justified
question.
Recognizing an object of the outer world in its essential being
cannot, after all, possibly mean perceiving it with the senses, and
as it presents itself to them, so drawing up a likeness of it. One
will never see how, from something sensory, a corresponding
conceptual photograph could come about, and what relation there could
be between the two. An epistemology that starts from this standpoint
can never get clear about the question of the connection of concept
and object.
[see note 2]
How is one to see the necessity of going
beyond what is given immediately by the sense, to the concept, if in
the former the essential being of an object of the sensory world were
already given? Why the conceptual comprehending too, if the
looking-at were already sufficient? At the least, the concept, if not
a falsification, would be a highly unnecessary addition to the
object. That is what one must arrive at, if one denies the
concreteness of concepts and laws. Over against such pictorial
explanations as, say, that of the Herbartian school, too: that the
concept is the mental correlate of an object located outside us, and
that the recognizing consists in acquiring such a picture, we now
want to seek a reality explanation of recognizing. In keeping with
the task we set ourselves, we here want to limit ourselves merely to
the recognizing of the outer world. In this case, two things come
into consideration in the act of recognizing: The
confirmation
[see translator's note 1]
of thinking, and that of the
senses. The former has to do with concepts and laws, the latter with
sensory qualities and processes. The concept and the law are always
something general, the sensory object something particular; the
former can only be thought, the latter only looked at. The media
through which the general appears to us as something particular are
space and time. Every particular thing and every particular process
must be able to be fitted into the conceptual content of the world,
for whatever of it were not lawful and conceptual in nature does not
come into consideration for our thinking at all. Hence, recognizing
an object can only mean: giving what appears to our senses, in space,
a place in the generality of the conceptual content of the world,
indeed letting it merge into it completely. In the recognizing of a
spatial-temporal object, we are thus given nothing else than a
concept or law in a sense-perceptible way. Only by such a conception
does one get over the previously mentioned unclearness. One must
allow the concept its primariness, its own form of existence, built
upon itself, and only recognize it again in another form in the
sense-perceptible object. Thus we have reached a reality definition
of Experience. The philosophy of induction can by its nature never
reach a definition of this kind. For it would have to be shown in
what way experience transmits concept and law. But since that
philosophy sees these two as something merely subjective, its path to
that is cut off from the beginning.
From this, one sees at the same time how unfruitful the undertaking
would be to want to make out anything about the outer world without
the help of perception. How can one gain possession of the concept in
the form of viewing, without accomplishing the viewing itself? Only
when one sees that what perception offers is concept and idea, but in
an essentially other form than in pure thinking's form freed of all
empirical content, and that this form is what makes the difference,
does one comprehend that one must take the path of experience. But if
one assumes the content to be what matters, then nothing can be put
forth against the assertion that the same content could after all
also be acquired in a manner independent of all experience. So
experience must indeed be the maxim of the philosophy of nature, but
at the same time, recognition of the concept in the form of outer
experience. And here is where modern natural science, by seeking no
clear concept of experience, got on the wrong track. In this point it
has been attacked repeatedly, and is also easily open to attack.
Instead of acknowledging the apriority of the concept, and taking the
sense world as but another form of the same, it regards the same as a
mere derivative of the outer world, which for it is an absolute
Prior. The mere form of something is thus stamped the thing itself.
Atomism, to the extent that it is materialistic, issues from this
unclearness of the concepts. We want here, based on the preceding, to
subject it to a careful, and — as I believe I can assume —
the only possible, critique.
However opinions may diverge in the detail, atomism
ultimately amounts to regarding all sensory qualities, such as: tone,
warmth, light, scent, and so on, indeed, if one considers the way
thermodynamics derives Boyle's law, even pressure, as mere semblance,
mere function of the world of atoms. Only the atom counts as ultimate
factor of reality. To be consistent, one must now deny it every
sensory quality,because otherwise a thing would be explained out of
itself. One did, to be sure, when one set about to build up an
atomistic world system,
[see note 3]
attribute to the atom all
kinds of sensory qualities, albeit only in quite meager abstraction.
One regards it, now as extended and impenetrable, now as mere energy
center, etc. But thereby one committed the greatest inconsistency,
and showed that one had not considered the above, which shows quite
clearly that no sensory characteristics whatsoever may be attributed
to the atom at all. Atoms must have an existence inaccessible to
sensory experience. On the other hand, though, also, they themselves,
and also the processes occurring in the world of atoms, especially
movements, are not supposed to be something merely conceptual. The
concept, after all, is something merely universal, which is without
spatial existence. But the atom is supposed, even if not itself
spatial, yet to be there in space, to present something particular.
It is not supposed to be exhausted in its concept, but rather to
have, beyond that, a form of existence in space. With that, there is
taken into the concept of the atom a property that annihilates it.
The atom is supposed to exist analogously to the objects of outer
perception, yet not be able to be perceived. In its concept,
viewability is at once affirmed and denied.
Moreover, the atom proclaims itself right away as a mere product of
speculation. When one leaves out the previously mentioned sensory
qualities quite unjustifiably attributed to it, nothing is left for
it but the mere “Something,” which is of course unalterable,
because there is nothing about it, so nothing can be destroyed, either.
The thought of mere being, transposed into space, a mere thought-point,
basically just the arbitrarily multiplied Kantian “thing in
itself,” confronts us.
Against this, one could perhaps
object that after all it is all the same what is understood by Atom,
that one should let the scholar of natural history go ahead and
operate with it — for in many tasks of mathematical physics,
atomistic models are indeed advantageous —; that after all, the
philosopher knows that one is not dealing with a spatial reality, but
with an abstraction, like other mathematical notions. To oppose the
assumption of the atom in this respect would indeed be mistaken. But
that is not the issue. The philosophers are concerned with that
atomism for which atom and causality
[see note 4]
are the only
possible motivating forces of the world, which either denies all that
is not mechanical, or else holds it to be inexplicable, as exceeding
our cognitive ability.
[see note 5]
It is one thing to view the
atom as a mere thought-point, another thing to want to see in it the
fundamental principle of all existence. The former standpoint never
goes beyond mechanical nature with it; the second holds everything to
be a mechanical function.
If someone wanted to speak of the harmlessness of the atomistic
notions, one could, to refute him, go ahead and hold up to him the
consequences that have been derived from them. There are especially
two necessary consequences: firstly, that the predicate of original
existence is squandered on isolated substances void of spirit, quite
indifferent toward one another, and otherwise wholly undefined, in
whose interaction only mechanical necessity rules, so that the entire
remainder of the world of phenomena exists as their empty haze, and
has mere chance to thank for its existence; secondly, insurmountable
limits to our recognizing result from this. For the human mind, the
concept of the atom is, as we have shown, something completely empty,
the mere “Something.” But since the atomists cannot be
content with this content, but call for actual substance, yet determine
this substance in a way in which it can nowhere be given, they must
proclaim the unrecognizability of the actual essential being of the
atom.
Concerning the other limit of
knowledge, the following is to be noted. If one sees thinking too as
a function of the interaction of complexes of atoms, which remain
indifferent toward one another, it is not at all to be marveled at,
why the connection between movement of the atoms on the one hand, and
thinking and sensation on the other, is not to be
comprehended,
[see note 6]
which atomism therefore sees as a
limit of our recognition. Only, there is something to comprehend only
where a conceptual passage over exists. But if one first so limits
the concepts that in the sphere of the one, nothing is to be found
that would make possible the passage to the sphere of the other, then
comprehending is excluded from the start. Moreover, this passage
would have to be indeed not of a merely speculative nature, but
rather it would have to be a real process, thus permitting of being
demonstrated. But this is again prevented by the non-sensoriness of
atomistic motion. With the giving up of the concept of the atom,
these speculations about the limit of our knowledge fall away by
themselves. From nothing must one guard oneself more than from such
determinations of boundary, for beyond the boundary there is then
room for everything possible. The most irrational spiritism, as well
as the most nonsensical dogma, could hide behind such assumptions.
The same are quite easy to refute in every single case, by showing
that at their foundation there always lies the mistake of seeing a
mere abstraction for more than it is, or holding merely relative
concepts to be absolute ones, and similar errors. A large number of
false notions has come into circulation especially through the
incorrect concepts of space and time.
[see note 7]
Hence we must subject these two concepts to a
discussion. The mechanistic explanation of nature needs for the
assumption of its world of atoms, besides the atoms in motion
absolute space as well, that is, an empty vacuum, and an absolute
time, that is, an unalterable measure of the One-After-Another.
[see note 8]
But what is space? Absolute
extension can be the only answer. Only, that is only a characteristic
of sensory objects, and apart from these a mere abstraction, existent
only upon and with the objects, and not beside them as atomism must
necessarily assume. If extension is to be present, something must be
extended, and this cannot again be Extension. Here, for a proof of
the absoluteness of space, one will be able to raise as an objection,
say, the Kantian invention about the two gloves of the left and right
hand. One says, their parts have, after all, the same relationship to
one another, and yet one cannot make the two congruent. From this,
Kant concludes that the relationship to absolute space is a different
one, hence absolute space exists. But it is more obvious, after all,
to assume that the relationship of the two gloves to one another is
simply such that they cannot be made congruent. How should a
relationship to absolute space be thought of, anyway? And even
assuming it were possible, the relationships of the two gloves to
absolute space would, however, only then establish in turn a
relationship of the two gloves to one another. Why should this
relationship not just as well be able to be a primary one? Space,
apart from the things of the world of the senses, is an absurdity. As
space is only something upon the objects, so time is also given only
upon and with the processes of the world of the senses. It is
inherent in them. By themselves, both are mere abstractions. Only the
sensory things and processes are concrete items of the world of the
senses. They present concepts and laws in the form of outer
existence. Therefore they in their simplest form must be a
fundamental pillar of the empirical study of nature. The simple
sensory quality and not the atom, the fundamental fact and not the
motion behind what is empirical, are the elements of the empirical
study of nature. It is thereby given a direction which is the only
possible one. If one takes that as a basis, one will not be tempted
at all to speak of limits of recognizing, because one is not dealing
with things to which one attributes arbitrary negative
characteristics such as supersensible and the like, but rather with
actually given concrete objects.
From these mentions, important conclusions will also result for
epistemology. But foremost, it is certain that the atom and the
motion behind the empirical must be exchanged for the fundamental
sensory elements of outer experience, and henceforth can no longer
count as principles of the study of nature.
