Man is not equally moral at all hours, this is well known. If his morality is judged to be the capability for great self-sacrificing resolutions and self-denial (which, when continuous and grown habitual, are called holiness)
Friedrich NietzschePeople who, out of an inborn moderation, leave every glass standing only half-emptied refuse to admit that everything in the world has its sediments and dregs.
Friedrich NietzscheI absolutely cannot see how one can later make up for having failed to go to a good school at the proper time. For this is what distinguishes the hard school as a good school from all others: that much is demanded; and sternly demanded; that the good, even the exceptional, is demanded as the norm; that praise is rare, that indulgence is nonexistent; that blame is apportioned sharply, objectively, without regard for talent or antecedents. What does one learn in a hard school? Obeying and commanding.
Friedrich NietzscheMan demands truth and fulfills this demand in moral intercourse with other men; this is the basis of all social life. One anticipates the unpleasant consequences of reciprocal lying. From this there arises the duty of truth. We permit epic poets to lie because we expect no detrimental consequences in this case. Thus the lie is permitted where it is considered something pleasant. Assuming that it does no harm, the lie is beautiful and charming.
