The assumed world of subject, substance, reason, etc., is necessary, an adjusting, simplifying falsifying, artificially-separating power resides in us. "Truth" is the will to be master over the manifold sensations that reach consciousness; it is the will to classify phenomena according to definite categories. In this way we start out with a belief in the "true nature" of things (we regard phenomena as real).
The character of the world in the process of Becoming is not susceptible of formulation; it is "false" and "contradicts itself." Knowledge and the process of evolution exclude each other. Consequently, knowledge must be something else: it must be preceded by a will to make things knowable, a kind of Becoming in itself must create the illusion of Being.
518.
If our "ego" is the only form of Being, according to which we make and understand all Being: very good! In that case it were very proper to doubt whether an illusion of perspective were not active here--the apparent unity which everything assumes in our eyes on the horizon-line. Appealing to the body for our guidance, we are confronted by such appalling manifoldness, that for the sake of method it is allowable to use that phenomenon which is richer and more easily studied as a clue to the understanding of the poorer phenomenon.
Finally: admitting that all is Becoming, knowledge is only possible when based on a belief in Being.
519.
If there is "only one form of Being, the ego," and all other forms of Being are made in its own image,--if, in short, the belief in the "ego," together with the belief in logic, stands and falls with the metaphysical truth of the categories of reason: if, in addition, the "ego" is shown to be something that is evolving: then----
520.
The continual transitions that occur, forbid our speaking of the "individual," etc.; the "number" of beings itself fluctuates. We should know nothing of time or of movement, if, in a rough way, we did not believe we saw things "standing still" behind or in front of things moving. We should also know just as little about cause and effect, and without the erroneous idea of "empty space" we should never have arrived at the concept of space at all. The principle of identity is based on the "fact of appearance" that there are some things alike. Strictly speaking, it would not be possible to "understand" and "know" an evolving world; something which is called "knowledge" exists only in so far as the "understanding" and "knowing" intellect already finds an adjusted and rough world to hand, fashioned out of a host of mere appearances, but become fixed to the extent in which this kind of appearance has helped to preserve life; only to this extent is "knowledge" possible--that is to say, as a measuring of earlier and more recent errors by one another.
521.
Concerning logical appearance.--The concept "individual" and the concept "species" are equally false and only apparent. "Species" only expresses the fact that an abundance of similar creatures come forth at the same time, and that the speed of their further growth and of their further transformation has been made almost imperceptible for a long time: so that the actual and trivial changes and increase of growth are of no account at all (--a stage of evolution in which the process of evolving is not visible, so that, not only does a state of equilibrium seem to have been reached, but the road is also made clear for the error of supposing that an actual goal has been reached--and that evolution had a goal...).
The form seems to be something enduring, and therefore valuable; but the form was invented merely by ourselves; and however often "the same form is attained," it does not signify that it is the same form,--because something new always appears; and we alone, who compare, reckon the new with the old, in so far as it resembles the latter, and embody the two in the unity of "form." As if a type had to be reached and were actually intended by the formative processes.
Form, species, law, idea, purpose--the same fault is made in respect of all these concepts, namely, that of giving a false realism to a piece of fiction: as if all phenomena were infused with some sort of obedient spirit--an artificial distinction is here made between that which acts and that which guides action (but both these things are only fixed in order to agree with our metaphysico-logical dogma: they are not "facts").
We should not interpret this constraint in ourselves, to imagine concepts, species, forms, purposes, and laws ("a world of identical cases") as if we were in a position to construct a real world; but as a constraint to adjust a world by means of which our existence will be ensured: we thereby create a world which is determinable, simplified, comprehensible, etc., for us.
The very same constraint is active in the functions of the senses which support the reason--by means of simplification, coarsening, accentuation, and interpretation; whereon all "recognition," all the ability of making one's self intelligible rests. Our needs have made our senses so precise, that the "same world of appearance" always returns, and has thus acquired the semblance of reality.
Our subjective constraint to have faith in logic, is expressive only of the fact that long before logic itself became conscious in us, we did nothing save introduce its postulates into the nature of things: now we find ourselves in their presence,--we can no longer help it,--and now we would fain believe that this constraint is a guarantee of "truth." We it was who created the "thing," the "same thing," the subject, the attribute, the action, the object, the substance, and the form, after we had carried the process of equalising, coarsening, and simplifying as far as possible. The world seems logical to us, because we have already made it logical.
522.
Fundamental solution.--We believe in reason: this is, however, the philosophy of colourless concepts. Language is built upon the most naïf prejudices.
Now we read discord and problems into things, because we are able to think only in the form of language--we also believe in the "eternal truth" of "wisdom" (for instance, subject, attribute, etc.).
We cease from thinking if we do not wish to think under the control of language; the most we can do is to attain to an attitude of doubt concerning the question whether the boundary here really is a boundary.
Rational thought is a process of interpreting according to a scheme which we cannot reject.
(f) Consciousness.
523.
There is no greater error than that of making psychical and physical phenomena the two faces, the two manifestations of the same substance. By this means nothing is explained: the concept "substance" is utterly useless as a means of explanation. Consciousness may be regarded as secondary, almost an indifferent and superfluous thing, probably destined to disappear and to be superseded by perfect automatism--
When we observe mental phenomena we may be likened to the deaf and dumb who divine the spoken word, which they do not hear, from the movements of the speaker's lips. From the appearance of the inner mind we draw conclusions concerning invisible and other phenomena, which we could ascertain if our powers of observation were adequate for the purpose.
For this inner world we have no finer organs, and that is why a complexity which is thousandfold reaches our consciousness as a simple entity, and we invent a process of causation in it, despite the fact that we can perceive no cause either of the movement or of the change--the sequence of thoughts and feelings is nothing more than their becoming visible to consciousness. That this sequence has anything to do with a chain of causes is not worthy of belief: consciousness never communicates an example of cause and effect to us.
524.
The part "consciousness" plays,--It is essential that one should not mistake the part that "consciousness plays" it is our relation to the outer world; it was the outer world that developed it. On the other hand, the direction--that is to say, the care and cautiousness which is concerned with the inter-relation of the bodily functions, does not enter into our consciousness any more than does the storing activity of the intellect: that there is a superior controlling force at work in these things cannot be doubted--a sort of directing committee, in which the various leading desires make their votes and their power felt. "Pleasure" and "pain" are indications which reach us from this sphere: as are also acts of will and ideas.
