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[Pg 37] 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.

Fundamental solution.—We believe in reason: this is, however, the philosophy of colourless concepts. Language is built upon the most naf 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.
In short: That which becomes conscious has causal relations which are completely and absolutely concealed from our knowledge—the sequence of thoughts, feelings, and ideas, in consciousness, does[Pg 40] not signify that the order in which they come is a causal order: it is so apparently, however, in the highest degree. We have based the whole of our notion of intellect, reason, logic, etc., upon this apparent truth (all these things do not exist: they are imaginary syntheses and entities), and we then projected the latter into and behind all things!
As a rule consciousness itself is understood to be the general sensorium and highest ruling centre; albeit, it is only a means of communication: it was developed by intercourse, and with a view to the interests of intercourse.... "Intercourse" is understood, here, as "relation," and is intended to cover the action of the outer world upon us and our necessary response to it, as also our actual influence upon the outer world. It is not the conducting force, but an organ of the latter.
525.
My principle, compressed into a formula which savours of antiquity, of Christianity, Scholasticism, and other kinds of musk: in the concept, "God is spirit," God as perfection is "denied...."
526.
Wherever people have observed a certain unity in the grouping of things, spirit has always been regarded as the cause of this co-ordination: an assumption for which reasons are entirely lacking. Why should the idea of a complex fact be one of the conditions of that fact? Or why should[Pg 41] the notion of a complex fact have to precede it as its cause?
We must be on our guard against explaining finality by the spirit: there is absolutely no reason whatever for ascribing to spirit the peculiar power of organising and systematising. The domain of the nervous system is much more extensive: the realm of consciousness is superadded. In the collective process of adaptation and systematising, consciousness plays no part at all.
527.
Physiologists, like philosophers, believe that consciousness increases in value in proportion as it gains in clearness: the most lucid consciousness and the most logical and impassive thought are of the first order. Meanwhile—according to what standard is this value determined?—In regard to the discharge of will-power the most superficial and most simple thought is the most useful—it might therefore, etc. etc. (because it leaves few motives over).
