Only a fairy tale calls a constant condition 'happiness'.

True universality does not consist in knowing much but in loving much.

There might be a fact of the greatest significance reported by Thucydides which will only be recognized as such a hundred years from now.

The seventeenth century is everywhere a time in which the state's power over everything individual increases, whether that power be in absolutist hands or may be considered the result of a contract, etc. People begin to dispute the sacred right of the individual ruler or authority without being aware that at the same time they are playing into the hands of a colossal state power.

To each eye, perhaps, the outlines of a great civilization present a different picture. In the wide ocean upon which we venture, the possible ways and directions are many; and the same studies which have served for my work might easily, in other hands, not only receive a wholly different treatment and application, but lead to essentially different conclusions.

Great men are necessary for our life, in order that the movement of world history can free itself sporadically, by fits and starts, from obsolete ways of living and inconsequential talk.

Only the fairy tale equates changelessness with happiness...Permanence means paralysis and death. Only, in movement, with all its pain, is life.
