Note 17 — Chapter V · LIFE OF PLATO.
Reading edition
Ælian (V. H. iii. 27) had read a story to the effect, that Plato, in consequence of poverty, was about to seek military service abroad, and was buying arms for the purpose, when he was induced to stay by the exhortation of Sokrates, who prevailed upon him to devote himself to philosophy at home.
If there be any truth in this story, it must refer to some time in the interval between the restoration of the democracy (403 B.C.) and the death of Sokrates (399 B.C.). The military service of Plato, prior to the battle of Ægospotami (405 B.C.), must have been obligatory, in defence of his country, not depending on his own free choice. It is possible also that Plato may have been for the time impoverished, like many other citizens, by the intestine troubles in Attica, and may have contemplated military service abroad, like Xenophon.
But I am inclined to think that the story is unfounded, and that it arises from some confusion between Plato and Xenophon.
