Truth springs from argument amongst friends.

Beauty, whether moral or natural, is felt, more properly than perceived.

Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty.

The rules of morality are not the conclusion of our reason.

It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger.

We may conclude, therefore, that, in order to establish laws for the regulation of property, we must be acquainted with the nature and situation of man; must reject appearances, which may be false, though specious; and must search for those rules, which are, on the whole, most useful and beneficial.

The heart of man is made to reconcile the most glaring contradictions.
