According to Aristotle, one possesses the virtue of fortitude if he/she “faces and … fears the right things … from the right motive, in the right way and from the right time, and who feels confidence under the corresponding conditions.” In other words, a brave person is one who prudently decides in certain situations that it is right to endure suffering for the sake of a good, even though he is afraid. Indeed, the brave person endures suffering in cases where he knows that avoiding it would be a greater evil.
