The exact character of the development which the Socratic teaching received from Euclides and his school is a matter of considerable doubt. The allusions to the tenets of the school in Plato and [223] others are only fragmentary. We gather, however, from them that Euclides was wholly antithetical to the personal turn given to philosophy, both by the Cyrenaics and the Cynics. He revived and developed with much dialectical subtlety the metaphysical system of Parmenides and the Eleatics, maintaining that there is but one absolute existence, and that sense and sense-perceptions as against this [224] are nothing. This one absolute existence was alone absolutely good, and the good for man could only be found in such an absorption of himself in this one absolute good through reason and contemplation, as would bring his spirit into perfectness of union with it. Such absorption raised a man above the troubles and pains of life, and thus, in insensibility to these through reason, man attained his highest good. The school is perhaps interesting only in so far as it marks the continued survival of the abstract dialectic method of earlier philosophy. As such it had a very definite influence, sometimes through agreement, sometimes by controversy, on the systems of Plato and Aristotle now to be dealt with. {134} CHAPTER XIV PLATO _Student and wanderer--The Dialogues--Immortal longings--Art is love--Knowledge through remembrance--Platonic love_ [239] This great master, the Shakespeare of Greek philosophy, as one may call him, for his fertility, his variety, his humour, his imagination, his poetic grace, was born at Athens in the year 429 B.C. He was of noble family, numbering among his ancestors no less a man than the great lawgiver Solon, and tracing back his descent even further to the [240] legendary Codrus, last king of Athens. At a very early age he seems to have begun to study the philosophers, Heraclitus more particularly, and before he was twenty he had written a tragedy. About that time, however, he met Socrates; and at once giving up all thought of poetic fame he burnt his poem, and devoted himself to the hearing of Socrates. For ten years he was his constant companion. When Socrates met his death in 399, Plato and other followers of the master fled at first to Megara, as already mentioned (above, p. 132); he then entered on a period of extended travel, first to Cyrene and {135} Egypt, thence to Italy and Sicily. In Italy he devoted himself specially to a study of the doctrine of Pythagoras. It is said that at Syracuse he offended the tyrant Dionysius the elder by his freedom of speech, and was delivered up to the Spartans, who were then at war with Athens. [241] Ultimately he was ransomed, and found his way back to Athens, but he is said to have paid a second visit to Sicily when the younger Dionysius became tyrant. He seems to have entertained the hope that he might so
