Was Plato a stoic?
In the strictest sense of the word, Plato was not a Stoic: the Stoic ‘school’ originated with Zeno of Citium, at Athens, ca. 300 B.C., several decades after Plato’s death. Zeno and the later Stoics were undoubtedly influenced themes and ideas raised in Plato’s writings (as well as Aristotle’s), but this is far as the connection goes.
