Custom is the plague of wise men and the idol of fools.

We do everything by custom, even believe by it; our very axioms, let us boast of free-thinking as we may, are oftenest simply such beliefs as we have never heard questioned.

Custom governs the world; it is the tyrant of our feeling and our manners, and rules us with the imperious hand of a despot

What is philosophy but a continual battle against custom?

Custom is the principle magistrate of man's life.

There is no tyrant like custom, and no freedom where its edicts are not resisted.
