Whether fortitude deals chiefly with sudden occurrences?

Objections

Objection 1 : It seems that fortitude does not deal chiefly with sudden occurrences. For it would seem that things occur suddenly when they are unforeseen. But Tully says (De Invent. Rhet. ii) that "fortitude is the deliberate facing of danger, and bearing of toil." Therefore fortitude does not deal chiefly with sudden happenings.
Objection 2 : Further, Ambrose says (De Offic. i): "The brave man is not unmindful of what may be likely to happen; he takes measures beforehand, and looks out as from the conning-tower of his mind, so as to encounter the future by his forethought, lest he should say afterwards: This befell me because I did not think it could possibly happen." But it is not possible to be prepared for the future in the case of sudden occurrences. Therefore the operation of fortitude is not concerned with sudden happenings.
Objection 3 : Further, the Philosopher says (Ethic. iii, 8) that the "brave man is of good hope." But hope looks forward to the future, which is inconsistent with sudden occurrences. Therefore the operation of fortitude is not concerned with sudden happenings.
