regards Philosophy; they study Fries, and heaven knows whom else. Their hearts are full of the true, good and beautiful; they would know and see what they ought to do, but their breasts swell with goodwill alone. While Socrates remained at the good and universal, at implicitly concrete thoughts, without having developed them or having revealed them through development, Plato certainly goes on to the Idea as determined. His defect, however, is that this determinateness and that universality are still outside one another. We should certainly obtain the determinate Idea by reducing the dialectic movement to its result, and that forms an important element in knowledge. Yet when Plato speaks of justice, beauty, goodness, truth, their origin is not revealed; they are not shown as being results, but merely as hypotheses accepted in their immediacy. Consciousness certainly has an innate conviction that they form the highest end, but this their determination is not discovered. Since Plato’s dogmatic expositions of Ideas are lost (_supra_, p. 11), the dialectic of pure thought is only placed before us by the Dialogues dealing with the subject, and these, just because they deal with pure thought, are amongst the most difficult, viz.: the Sophist, the Philebus, and, more especially, the Parmenides. We here pass over the Dialogues which contain only negative dialectic and Socratic dialogue, because they treat only of concrete ideas and not of dialectic in its higher signification; they leave us unsatisfied, because their ultimate end is only to confuse one’s opinions, or awaken a sense of the necessity for knowledge. But those three express the abstract speculative Idea in its pure Notion. The embracing of the opposites in one, and the expression of this unity, is chiefly lacking in the Parmenides, which has hence, like some other Dialogues, only a negative result. But both in the Sophist and the Philebus Plato expresses the unity also.
