“The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding go out to meet it.”Tucidide · Istoria războiului peloponesiac · -400 · II, 40
Thucydides, through Pericles, defines courage not as ignorance of danger but as a conscious choice. The soldier who goes into battle knowing he may die, but does so for a greater good, is braver than one who doesn't understand the risk. The mechanism is clear vision combined with resolve.
Why it matters In career or personal life, this idea encourages you not to avoid unpleasant information but to act despite it.
