(_α_) “If we wish to follow this up, and do so in accordance with the understanding, not merely stumbling over it like Empedocles, we should say that friendship is the principle of good and strife the principle of evil, so that in a measure we may assert that Empedocles maintained—and was the first to do so—that the evil and the good are the absolute principles, because the good is the principle of all good, and the bad the principle of all evil.” Aristotle shows the trace of universality present here; for to him it may be termed essential in dealing with the Notion of the principle, that which is in and for itself. But this is only the Notion, or the thought which is present in and for itself; we have not yet seen such a principle, for we find it first in Anaxagoras. If Aristotle found the principle of motion missed in ancient philosophers, in the Becoming of Heraclitus, he again missed in Heraclitus the still deeper principle of the Good, and hence wished to discover it in Empedocles. By the good the “why” is to be understood, that which is an end in and for itself, which is clearly established in itself, which is on its own account, and through which all else is; the end has the determination of activity, the bringing forth of itself, so that it, as end to itself, is the Idea, the Notion that makes itself objective and, in its objectivity, is identical with itself. Aristotle thus entirely controverts Heraclitus, because his principle is change alone, without remaining like self, maintaining self, and going back within self.
