The Greek Philosophy is free from restraint because it does not yet have regard to the opposition between Being and Thought, but proceeds from the unconscious presupposition that Thought is also Being. Certainly certain stages in the Greek Philosophy are laid hold of which seem to stand on the same platform as the Christian philosophies. Thus when we see, for instance, in the Philosophy of the Sophists, the new Academics, and the Sceptics, that they maintain the doctrine that the truth is not capable of being known, they might appear to accord with the later subjective philosophies in asserting that all thought-determinations were only subjective in character, and that hence from these no conclusions could be arrived at as regards what is objective. But there is really a difference. In the case of ancient philosophies, which said that we know only the phenomenal, everything is confined to that; it is as regards practical life that the new Academy and the Sceptics also admitted the possibility of conducting oneself rightly, morally and rationally, when one adopts the phenomenal as one’s rule and guide in life. But though it is the phenomenal that lies at the foundation of things, it is not asserted that there is likewise a knowledge of the true and existent, as in the case of the merely subjective idealists of a more modern day. These last still keep in the background a potentiality, a beyond which cannot be known through thought or through conception. This other knowledge is an immediate knowledge—a faith in, a view of, and a yearning after, the beyond such as was evinced by Jacobi. The ancients have no such yearning; on the contrary, they have perfect satisfaction and rest in the certitude that only that which appears is for Knowledge. Thus it is necessary in this respect to keep strictly to the point of view from which we start, else through the similarity of the results, we come to see in that old Philosophy all the determinate character of modern subjectivity. Since in the simplicity of ancient philosophy the phenomenal was itself the only sphere, doubts as to objective thought were not present to it.
