Aristotle, Nicomachean Ethics
H. Rackham, Ed.

But it is also true that the virtuous man's conduct is often guided by the interests of his friends and of his country, and that he will if necessary lay down his life in their behalf. For he will surrender wealth and power and all the goods that men struggle to win, if he can secure nobility for himself; since he would prefer an hour of rapture to a long period of mild enjoyment, a year of noble life to many years of ordinary existence, one great and glorious exploit to many small successes. And this is doubtless the case with those who give their lives for others; thus they choose great nobility for themselves. Also the virtuous man is ready to forgo money if by that means his friends may gain more money; for thus, though his friend gets money, he himself achieves nobility, and so he assigns the greater good to his own share.
