Quote from : Of Human Bondage Book

It is clear that men accept an immediate pain rather than an immediate pleasure, but only because they expect a greater pleasure in the future. Often the pleasure is illusory, but their error in calculation is no refutation of the rule. You are puzzled because you cannot get over the idea that pleasures are only of the sense; but, child, a man who dies for his country dies because he likes it as surely as a man eats pickled cabbage because he likes it.
