Sayings of Socrates 18

Someone will say: And are you not ashamed, Socrates, of a course of life which is likely to bring you to an untimely end? 

To him I may fairly answer: There you are mistaken. A man who is good for anything ought not to calculate the chance of living or dying; he ought only to consider whether in doing anything he is doing right or wrong—acting the part of a good man or of a bad man. 

. . . For wherever a man's place is, whether the place he has chosen, or that where he has been placed by a commander, there he ought to remain in the hour of danger; he should not think of death, or of anything, but only of disgrace. 

—Plato, Apology 28b–d
