“Each generation thinks it invented sex; each generation is totally mistaken. Anything along that line today was commonplace both in Pompeii and in Victorian England; the differences lie only in the degree of coverup — if any.”

Day of Affirmation Address (1966)
Variant: Few will have the greatness to bend history, but each of us can work to change a small portion of the events, and then the total — all of these acts — will be written in the history of this generation.

Jede Vorstellung ist eine Verallgemeinerung, und diese gehört dem Denken an. Etwas allgemein machen, heißt, es denken.
"Grundlinien der Philosophie des Rechts oder Naturrecht und Staatswissenschaft im Grundrisse", Berlin, 1833, p. 35
"Every representation is a generalization, and this is inherent in thought. To generalize something means to think it."
"Any idea is a universalization, and universalizing is a property of thinking. To universalize something means to think."
"An idea is always a generalization, and generalization is a property of thinking. To generalize means to think."
Elements of the Philosophy of Right (1820/1821)

Music and Moonlight (1874), Ode
Context: A breath of our inspiration
Is the life of each generation;
A wondrous thing of our dreaming
Unearthly, impossible seeming —
The soldier, the king, and the peasant
Are working together in one,
Till our dream shall become their present,
And their work in the world be done.
