Aristotle, Nicomachean Ethics
H. Rackham, Ed.

[4] If then the same is true of Courage, the death or wounds that it may bring will be painful to the courageous man, and he will suffer them unwillingly; but he will endure them because it is noble to do so, or because it is base not to do so. And the more complete his virtue, and the fuller the happiness he has attained, the more pain will death cause him; for to such a man life is worth most, and he stands to lose the greatest goods, and knows that this is so, and this must be painful. But he is none the less courageous on that account, perhaps indeed he is more so, because he prefers glory in war to the greatest prizes of life.
