Laches is a Platonic dialogue from the early 4th century BC that examines the nature of courage and its role in educating the young. Lysimachus and Melesias seek advice from generals Nicias and Laches on whether training in fighting with armor is worthwhile. Laches views courage as simply enduring hardships without retreat, while Nicias argues it must be tied to knowledge of fear and moral understanding. Socrates guides the discussion, exposing the inadequacy of their definitions and urging them to recognize their ignorance and pursue deeper learning. The dialogue ultimately highlights that true virtue, including courage, rests upon wisdom and the right understanding of good and evil.
