The decrees of Fortune may be postponed, but they can never be vacated. He who imagines that he can avoid these rulings is like the man who exerts his limited control over a raft traveling on a swiftly-moving river; he may be able to organize the furnishings on his raft, but it is the river that decides his course. It swirls him about in its currents and eddies; it pushes him against projecting rocks and rapids; and its flux holds him firmly in its aquatic grip. Individual effort can arrest or divert this course, but only under certain conditions. Most men are unable to summon the required exertions of will necessary to resist such implacable torrents. We celebrate heroism because it is so uncommon, and because it represents, in some ways, a kind of conscious rebellion against Fortune’s unfeeling mandates.
