The Greatest Danger

Fortitude strengthens man's mind against the greatest danger, which is that of death.

Aquinas wrote this in the Summa Theologica during the 1260s and 70s, in his treatise on the cardinal virtues, placing fortitude alongside prudence, justice, and temperance. For Aquinas, fortitude was not recklessness but the firmness of mind that allows a person to act rightly even when facing the worst fear a human being can know. He drew on Aristotle but pushed further, arguing that true courage is always ordered toward the good, not toward danger for its own sake. The teaching still matters because most of what unsettles us today is a smaller version of that same fear, and the same firmness is what carries us through it.
