For example, which is the most important? The slogan of the movement of the wise is "Man is the measure of all things", which puts man at the center of society and the world.

His conventionalism thought is the theoretical basis of slave-owner democracy, and it also has a far-reaching influence on the social contract theory of modern western bourgeoisie. The core of the Enlightenment is humanism, which opposes religious asceticism, attaches importance to secular happiness, is optimistic and enterprising, and affirms human value. The Reformation opposed complicated religious rituals, interfered with secular politics, and took the Bible as the only basis of belief. The Enlightenment advocated freedom, democracy, equality and fraternity.
