People usually think according to their inclinations, speak according to their learning and ingrained opinions, but generally act according to custom.

The empire of custom is most mighty.

Without the aid of prejudice and custom, I should not be able to find my way across the room.

The way of the world is to make laws, but follow custom.

A crime persevered in a thousand centuries ceases to be a crime, and becomes a virtue. This is the law of custom, and custom supersedes all other forms of law.

Nothing is more powerful than custom or habit.

Custom is a tyrant.
