Socrates questioned four historical Athenian figures through dialogues: [1] Charmides, a 17-year old unsure of his identity; [2] Ion, an actor who only liked Homer's poetry; [3] Alcibiades, a talented but morally vacant youth; and [4] Laches, a general concerned with courageous education for his sons. The document discusses whether Socrates undermined or conserved Athenian values through his interrogations, and analyzes what could give courage according to the dialogue Laches.
