Aristotle

We may say, however, that we all aspire after what seems to be good,only we are not masters of appearances,and the appearance which the end takes in the eyes of each of us depends on his character. But if each of us is in some degree responsible for his character, he will in some degree be responsible for the appearance; in not, nobody is responsible for his evil doing, everybody was as he does form ignorance of the end, under the impression that by this means he is gaining the supreme good, the aspiration after the true end is not a matter of our choice,and a man must be born with a sort of vision to enable him to form a noble judgment and choose what is truly good. He then who is endowed with this noblest of all gifts, a gift which can never be received nor learned from any body else, but must always be kept as Nature herself kept it. To possess this natural gift of virtue and honor is to have a perfect and true excellence of nature.
