Xenophon is remembered philosophically for a number of writings in which he sets out to rehabilitate Socrates from the various charges that led to his death. His Socrates tends to be a more reasonable kind of chap than that of Plato; for example, instead of embracing the Socratic paradox of identifying virtue with knowledge, he is aware that a training of the sentiments may be needed in order to keep knowledge of what one should do vivid in one’s mind at the crucial moment.
