Contumely always falls upon those who break through some custom or convention. Such men, in fact, are called criminals. Everyone who overthrows an existing law is, at the start, regarded as a wicket man. Long afterward, when it is found that this law was bad and so cannot be re-established, the epithet is changed. All history treats almost exclusively of wicked men who, in the course of time, have come to be looked upon as good men. All progress is the result of successful crimes.

Friedrich Nietzsche (1844-1900) German philosopher and poet

The Dawn [Morgenröte], sec. 20 (1881) [Mencken (1907)]

Alternate translations:

We have to make good a great deal of the contumely which has fallen on all those who, by their actions, have broken through the conventionality of some custom -- such people generally have been called criminals. Everybody who overthrew the existing moral law has hitherto, at least in the beginning, been considered a wicked man; but when afterwards, as sometimes happened, the old law could not be re-established and had to be abandoned, the epithet was gradually changed. History almost exclusively treats of such wicked men who, in the course of time, have been declared good men.
[tr. Volz (1903)]

One has to take back much of the defamation which people have cast upon all those who broke through the spell of a custom by means of a deed -- in general, they are called criminals. Whoever has overthrown an existing law of custom has hitherto always first been accounted a bad man: but when, as did happen the laws could not afterwards be reinstated and this fact was accepted, the predicate gradually changed -- history treats almost exclusively of these bad men who subsequently became good men!
[tr. Hollingdale (1997)]
