Laches

The Laches is a Socratic dialogue written by Plato. Participants in the discourse present competing definitions of the concept of courage. Lysimachus, son of Aristides, and Melesias, son of Thucydides, request advice from Laches and Nicias on whether or not they should have their sons trained to fight in armor. After each gives their opinion, Nicias for and Laches against, they seek Socrates for counsel.
