This has four dialogues that take us through, as the title reveals, Socrates's trial & final days. Euthyphro is a debate on the nature of piety as Socrates waits outside the courthouse, while Apology is a one-man monologue where a feisty Socrates argues against the charges brought upon him. Crito sees him in prison arguing with his rich pal on the nature of justice, while Phaedo is the longest, densest dialogue here, on the nature of the soul.
