On Courage, From Paul Tillich's "The Courage to Be"

“…The aristocratic element in the doctrine of courage was preserved as well as restricted by Aristotle. The motive for withstanding pain and death courageously is, according to him, that it is noble to do so and base not to do so. The courageous man acts ‘for the sake of what is noble, for that is the aim of virtue.’ ‘Noble,’ in these and other passages, is the translation of kalós and “base” is the translation of aischró, words which usually are rendered by ‘beautiful’ and ‘ugly.’ A beautiful or noble deed is a deed to be praised. Courage does what is to be praised and rejects what is to be despised. One praises that in which a being fulfills its potentialities or actualizes its perfections. Courage is the affirmation of one’s essential nature, one’s inner aim or entelechy, but it is an affirmation which has in itself the character of ‘in spite of.’ It includes the possible and, in some cases, the unavoidable sacrifice of elements which also belong to one’s being but which, if not sacrificed, would prevent us from reaching our actual fulfillment. This sacrifice may include pleasure, happiness, even one’s own existence. In any case it is praiseworthy, because in the act of courage the most essential part of our being prevails against the less essential. It is the beauty and goodness of courage that the good and the beautiful are actualized in it. Therefore it is noble.”
