Equality and similarity.
1. The coarser organ sees much apparent equality;
2. the spirit wants equality, i. e., to subsume a sense impression into an existing series: in the same way as the body assimilates inorganic matter.
Toward an understanding of logic: the will to equality is the will to power–the belief that something is thus and thus (the essence of judgment) is the consequence of a will that as much as possible shall be equal.
Logic is bound to the condition: assume there are identical cases. In fact, to make possible logical thinking and inferences, this condition must first be treated fictitiously as fulfilled. That is: the will to logical truth can be carried through only after a fundamental falsification of all events is assumed. From which it follows that a drive rules here that is capable of employing both means, firstly falsification, then the implementation of its own point of view: logic does not spring from will to truth.

The inventive force that invented categories labored in the service of our needs, namely of our need for security, for quick understanding on the basis of signs and sounds, for means of abbreviation:–”substance”, ”subject”, ”object”, ”being”, ”becoming” have nothing to do with metaphysical truths.–
It is the powerful who made the names of things into law, and among the powerful it is the greatest artists in abstraction who created the categories.
