The foul blemish on Kant's criticism has at last become visible even to the coarsest eyes: Kant had no right to his distinction "appearance" and "thing-in-itself,"--in his own writings he had deprived himself of the right of differentiating any longer in this old and hackneyed manner, seeing that he had condemned the practice of drawing any conclusions concerning the cause of an appearance from the appearance itself, as unallowable in accordance with his conception of the idea of causality and its purely intraphenomenal validity, and this conception, on the other hand, already anticipates that differentiation, as if the "thing in itself" were not only inferred but actually given.
554.
It is obvious that neither things-in-themselves nor appearances can be related to each other in the form of cause and effect: and from this it follows that the concept "cause and effect" is not applicable in a philosophy which believes in things-in-themselves and in appearances. Kant's mistake--... As a matter of fact, from a psychological standpoint, the concept "cause and effect" is derived from an attitude of mind which believes it sees the action of will upon will everywhere, which believes only in living things, and at bottom only in souls (not in things). Within the mechanical view of the world (which is logic and its application to space and time) that concept is reduced to the mathematical formula with which--and this is a fact which cannot be sufficiently emphasised--nothing is ever understood, but rather defined--deformed.
555.
The greatest of all fables is the one relating to knowledge. People would like to know how things-in-themselves are constituted: but behold, there are no things-in-themselves! But even supposing there were an "in-itself," an unconditional thing, it could on that very account not be known! Something unconditioned cannot be known: otherwise it would not be unconditioned! Knowing, however, is always a process of "coming into relation with something"; the knowledge-seeker, on this principle, wants the thing, which he would know, to be nothing to him, and to be nothing to anybody at all: and from this there results a contradiction,--in the first place, between this will to know, and this desire that the thing to be known should be nothing to him (wherefore know at all then?); and secondly, because something which is nothing to anybody, does not even exist, and therefore cannot be known. Knowing means: "to place one's self in relation with something," to feel one's self conditioned by something and one's self conditioning it under all circumstances, then, it is a process of making stable or fixed, of defining, of making conditions conscious (not a process of sounding things, creatures, or objects in-themselves).
556.
A "thing-in-itself" is just as absurd as a "sense-in-itself," a "meaning-in-itself." There is no such thing as a "fact-in-itself," for a meaning must always be given to it before it can become a fact.
The answer to the question, "What is that?" is a process of fixing a meaning from a different standpoint. The "essence" the "essential factor," is something which is only seen as a whole in perspective, and which presupposes a basis which is multifarious. Fundamentally the question is "What is that for me?" (for us, for everything that lives, etc. etc.).
A thing would be defined when all creatures had asked and answered this question, "What is that?" concerning it. Supposing that one single creature, with its own relations and standpoint in regard to all things, were lacking, that thing would still remain undefined.
In short: the essence of a thing is really only an opinion concerning that "thing." Or, better still; "it is worth" is actually what is meant by "it is" or by "that is."
One may not ask: "Who interprets, then?" for the act of interpreting itself as a form of the Will to Power, manifests itself (not as "Being," but as a process, as Becoming) as a passion.
The origin of "things" is wholly the work of the idealising, thinking, willing, and feeling subject. The concept thing as well as all its attributes.--Even "the subject" is a creation of this order, a "thing" like all others: a simplification, aiming at a definition of the power that fixes, invents, and thinks, as such, as distinct from all isolated fixing, inventing, and thinking. Thus a capacity defined or distinct from all other individual capacities; at bottom action conceived collectively in regard to all the action which has yet to come (action and the probability of similar action).
557.
The qualities of a thing are its effects upon other "things."
If one imagines other "things" to be non-existent, a thing has no qualities.
That is to say; there is nothing without other things.
That is to say; there is no "thing-in-itself."
558.
The thing-in-itself is nonsense. If I think all the "relations," all the "qualities" all the "activities" of a thing, away, the thing itself does not remain: for "thingness" was only invented fancifully by us to meet certain logical needs--that is to say, for the purposes of definition and comprehension (in order to correlate that multitude of relations, qualities, and activities).
559.
"Things which have a nature in themselves"--a dogmatic idea, which must be absolutely abandoned.
560.
That things should have a nature in themselves, quite apart from interpretation and subjectivity, is a perfectly idle hypothesis: it would presuppose that interpretation and the act of being subjective are not essential, that a thing divorced from all its relations can still be a thing.
Or, the other way round: the apparent objective character of things; might it not be merely the result of a difference of degree within the subject perceiving?--could not that which changes slowly strike us as being objective, lasting, Being, "in-itself"?--could not the objective view be only a false way of conceiving things and a contrast within the perceiving subject?
561.
If all unity were only unity as organisation. But the "thing" in which we believe was invented only as a substratum to the various attributes. If the thing "acts," it means: we regard all the other qualities which are to hand, and which are momentarily latent, as the cause accounting for the fact that one individual quality steps forward--that is to say, we take the sum of its qualities--x--as the cause of the quality x; which is obviously quite absurd and imbecile!
All unity is only so in the form of organisation and collective action: in the same way as a human community is a unity--that is to say, the reverse of atomic anarchy; thus it is a body politic, which stands for one, yet is not one.
