Until the day of his death, no man can be sure of his courage.

Anouilh’s line frames courage not as a fixed trait one can claim once and for all, but as something tested repeatedly across a lifetime. A person may act bravely in one crisis and falter in another; only the total arc of choices—especially under fear, pressure, or moral compromise—reveals what one’s “courage” amounts to. The reference to death underscores that self-knowledge is provisional: as long as life continues, new circumstances can overturn earlier self-assessments. The quote also hints at the theatrical and existential dimension common in Anouilh: identity is performed in situations, and the final reckoning of character is retrospective, not declarative.
