What is philosophy but a continual battle against custom?

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

Before philosophy can teach by Experience, the Philosophy has to be in readiness, the Experience must be gathered and intelligibly recorded.

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

There are three sources of belief: reason, custom, inspiration.
