The subject is one peculiarly attractive to a thinking man, not only on its own merits, but because of the ample and thoroughly trustworthy materials which we possess for forming a correct judgment. We are not here, as in the case of Pythagoras, sent to fish for fragments of truth among fanciful writers who lived several hundred years after the death of the object of their transcendental laudations; but, as in the gospel history, we have to deal with the intimate disciples and daily companions of the great hero of the story. We gather our knowledge of the life and philosophy of Socrates from Xenophon and Plato, both of whom have reported their intercourse with the philosopher in a tone of mingled admiration and sobriety which leaves no ground for suspicion. Only with regard to Plato we must take with us this caution, that he was both a poet by temperament and by mental habit a system-builder; and, as he chose to set forth his own speculations in a series of dramatic dialogues wherein Socrates is the chief speaker, we must beware of accepting, as standing on one common basis, the facts with regard to the life of Socrates brought forward in these compositions and the doctrines which are put into his mouth. With regard to the former, we may accept Plato’s evidence as a contemporary authority with the {3} utmost confidence; with regard to the latter, we must be constantly on our guard; and indeed, according to my view, it is wise never to accept any statement of Socrates’s doctrine from Plato, of which the germ at least does not lie plainly in Xenophon. For Xenophon, just because he was a less original man than Plato, a pleasing and graceful writer, somewhat on the level of our Addison, was for that reason free from the temptation, or rather had not the capacity, to interpolate anything into his account of the philosopher which was not consistent with the actual fact. He was a plain man, with no theories to support, and no pretensions to maintain; and as a faithful contemporary recorder of what he heard and saw, a more capable and trustworthy witness could not be desired. We shall therefore draw our sketch of the life and sayings of the great Athenian preacher mainly from his pleasant little book, introducing the idealist of the Academy only where he cannot be suspected of using his revered master as a mere dramatic engine, or where his superior literary powers have enabled him to paint a more effective picture.
