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).

"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?

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!
