“Evil is only imperfection, that which is not complete, which is becoming, but has not yet found its end.”

The History of Freedom in Christianity (1877)
Context: That men should understand that governments do not exist by divine right, and that arbitrary government is the violation of divine right, was no doubt the medicine suited to the malady under which Europe languished. But although the knowledge of this truth might become an element of salutary destruction, it could give little aid to progress and reform. Resistance to tyranny implied no faculty of constructing a legal government in its place. Tyburn tree may be a useful thing; but it is better still that the offender should live for repentance and reformation. The principles which discriminate in politics between good and evil, and make states worthy to last, were not yet found.

Variant: The end of a melody is not its goal: but nonetheless, had the melody not reached its end it would not have reached its goal either. A parable.

As quoted in The Observer (22 September 1957)
Context: What is history after all? History is facts which become lies in the end; legends are lies which become history in the end.

Context: For the state centralisation is the appropriate form of organisation, since it aims at the greatest possible uniformity in social life for the maintenance of political and social equilibrium. But for a movement whose very existence depends on prompt action at any favourable moment and on the independent thought and action of its supporters, centralism could but be a curse by weakening its power of decision and systematically repressing all immediate action … Organisation is, after all, only a means to an end. When it becomes an end in itself, it kills the spirit and the vital initiative of its members and sets up that domination by mediocrity which is the characteristic of all bureaucracies.
