There is no more striking case in history of the subtle continuity of thought than the relation between Plato and his master Socrates. The wonder of it is due to the absence of any formulation of doctrine on the part of Socrates himself. He only lived and talked; and yet Plato created a system of philosophy in which he is faithfully embodied. The form of embodiment is the dialogue, in which the talking of Socrates is perpetuated and conducted to profounder issues, and in which his life is both rendered and interpreted. But as the vehicle of Plato's thought preserves and makes perfect the Socratic method, so the thought itself begins with the Socratic motive and remains to the end an expression of it. The presentiment of perfect knowledge which distinguished Socrates from his contemporaries becomes in Plato the clear vision of a realm of ideal truth. [Sidenote: Platonism: Reality as the Absolute Ideal or Good.] § 160. Plato begins his philosophy with the philosopher and the philosopher's interest. The philosopher is a lover, who like all lovers longs for the beautiful. But he is the supreme lover, for he loves not the individual beautiful object but the Absolute Beauty itself. He is a lover too in that he does not possess, but somehow apprehends his object from afar. Though imperfect, he seeks perfection; though standing like all his fellows in the twilight of half-reality, he faces toward the sun. Now it is the fundamental proposition of the Platonic philosophy that reality is the sun itself, or the perfection whose possession every wise thinker covets, whose presence would satisfy every longing of experience. The real is that beloved object which is "truly beautiful, delicate, perfect, and blessed." There is both a serious ground for such an affirmation and an important truth in its meaning. The ground is the evident incompleteness of every special judgment concerning experience. We understand only in part, and we know that we understand only in part. What we discover is real enough for practical purposes, but even common-sense questions the true reality of its objects. Special judgments seem to terminate our thought abruptly and arbitrarily. We give "the best answer we can," but such answers do not come as the completion of our thinking. Our thought is in some sense surely a seeking, and it would appear that we are not permitted to rest and be satisfied at any stage of it. If we do so we are like the sophists--blind to our own ignorance. But it is equally true that our thought is straightforward and progressive. We are not permitted to return to earlier stages, but must push on to that which is not less, but more, than what we have as yet found. There is good hope, then, of understanding what the ideal may be from our knowledge of the direction which it impels us to follow.
