Sixty years ago I knew everything. Now I know nothing. Education is a progressive discovery of our own ignorance.

When liberty exceeds intelligence, it begets chaos, which begets dictatorship.

[H]istory assures us that civilizations decay quite leisurely.

In progressive societies the concentration[of wealth] may reach a point where the strength of number in the many poor rivals the strength of ability in the few rich; then the unstable equilibrium generates a critical situation, which history has diversely met by legislation redistributing wealth or by revolution distributing poverty.

So I should say that civilizations begin with religion and stoicism: they end with scepticism and unbelief, and the undisciplined pursuit of individual pleasure. A civilization is born stoic and dies epicurean.

The political machine triumphs because it is a united minority acting against a divided majority.

Civilization is social order promoting cultural creation. Four elements constitute it: economic provision, political organization, moral tradition, and the pursuit of knowledge and the arts. It begins where chaos and insecurity end. For when fear is overcome, curiosity and constructiveness are free, and man passes by natural impulse towards the understanding and embellishment of life.
