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.

"At some time in the development of thought, a point must have been reached when man became conscious of the fact that what he called the qualities of a thing were merely the sensations of the feeling subject: and thus the qualities ceased from belonging to the thing." The "thing-in-itself" remained over. 'The distinction between the thing-in-itself and the thing-for-us, is based upon that older and artless observation which would fain grant energy to things: but analysis revealed that even force was only ascribed to them by our fancy, as was also—substance. "The thing affects a subject?" Thus the root of the idea of substance is in language, not in things outside ourselves! The thing-in-itself is not a problem at all!
Being will have to be conceived as a sensation which is no longer based upon anything quite devoid of sensation.
In movement no new meaning is given to feeling. That which is, cannot be the substance of movement: it is therefore a form of Being.
N.B.—The explanation of life may be sought, in the first place, through mental images of phenomena which precede it (purposes);
Secondly, through mental images of phenomena which follow behind it (the mathematico-physical explanation).
The two should not be confounded. Thus: the physical explanation, which is the symbolisation of the world by means of feeling and thought, cannot in itself make feeling and thinking originate again and show its derivation: physics must rather construct the world of feeling, consistently without feeling or purpose right up to the highest man. And teleology is only a history of purposes, and is never physical.

Our method of acquiring "knowledge" is limited to a process of establishing quantities, but we can by no means help feeling the difference of quantity as differences of quality. Quality is merely a relative truth for us; it is not a "thing-in-itself."
