This universal principle is better characterized as Becoming, the truth of Being; since everything is and is not, Heraclitus hereby expressed that everything is Becoming. Not merely does origination belong to it, but passing away as well; both are not independent, but identical. It is a great advance in thought to pass from Being to Becoming, even if, as the first unity of opposite determinations, it is still abstract. Because in this relationship both must be unrestful and therefore contain within themselves the principle of life, the lack of motion which Aristotle has demonstrated in the earlier philosophies is supplied, and this last is even made to be the principle. This philosophy is thus not one past and gone; its principle is essential, and is to be found in the beginning of my Logic, immediately after Being and Nothing. The recognition of the fact that Being and non-being are abstractions devoid of truth, that the first truth is to be found in Becoming, forms a great advance. The understanding comprehends both as having truth and value in isolation; reason, on the other hand, recognizes the one in the other, and sees that in the one its “other” is contained. If we do not take the conception of existence as complete, the pure Being of simple thought in which everything definite is denied, is the absolute negative; but nothing is the same, or just this self-identity. We here have an absolute transition into the opposite which Zeno did not reach, for he remained at the proposition, “From nothing, comes nothing.” With Heraclitus, however, the moment of negativity is immanent, and the Notion of Philosophy as complete is therefore dealt with.
