This article aims to shed light on both the foundations and the consistency of the position regarding akrasia Xenophon attributes to Socrates in the Memorabilia. As does Plato's Socrates, Xenophon's Socrates maintains that akrasia is impossible in the presence of knowledge. On the other hand, he differs from the platonic Socrates by granting to enkrateia, instead of knowledge, the role of foundation for virtue. If enkrateia is the very condition for acquiring knowledge and virtue, consequently the responsibility for countering akrasia (...) falls to enkrateia. (shrink)
