About this book

Would you trust someone to teach courage if they could not tell you what it is?

Two fathers, Lysimachus and Melesias, want their sons to grow into men of distinction. They ask the generals Nicias and Laches whether lessons in fighting in armor will help. The generals disagree, and a practical choice about their children’s training opens a much harder question about what makes a person good.

In Plato’s short dialogue, Socrates asks what courage means before anyone claims to teach it. Laches points to a soldier who stands his ground; Nicias turns toward knowledge. As Socrates tests their answers, the conversation reaches beyond fighting to education, virtue, and care for the soul. What do these confident advisers really know?

What you’ll discover

  • A father's urgent question Begin with the familiar wish to give children the guidance they need to live well.
  • Generals who disagree Follow Nicias and Laches as a question about military lessons exposes different views of courage.
  • Plain questions, difficult answers Watch Socrates test confident claims with questions that ask for more than a single example.
  • Beyond standing your ground Explore why courage might require more than holding your post or simply enduring hardship.
  • Teaching starts with understanding Consider what teachers must know before they can claim to nurture virtue in someone else.

Is it for you?

This is for anyone curious about courage, teaching or raising children, and for readers who want a first, short taste of Socratic questioning. If you want a firm definition handed to you at the end, you may find it frustrating.

Laches by Plato, the cover

From the 15-minute summary · Key idea 1 of 6

Two fathers fear their sons will be nobodies

The dialogue opens with Lysimachus and Melesias, two older Athenians. Each is the son of a great man. Lysimachus is the son of Aristides, known as the Just, and Melesias is the son of Thucydides, a leading statesman. Both men admit a quiet shame. Their own fathers were so busy with public life that they never gave their sons much attention, and the sons have done nothing remarkable.

What is Laches by Plato about?

Laches is a dialogue about courage. Two fathers ask two generals whether their sons should learn fighting in armor, and Socrates turns the question into a search for what courage is and how virtue can be taught.

Who are the characters in Laches?

The speakers are Socrates, the generals Laches and Nicias, and two older Athenians, Lysimachus and Melesias. The fathers seek advice about educating their sons, who are named Aristides and Thucydides.

What is the main message of Laches?

The main message is that you cannot teach or practice a virtue well without knowing what it is. The dialogue also teaches that expertise matters more than majority opinion, and that honest questioning is a way to grow.
