Nature has placed mankind under the government of two sovereign masters, pain and pleasure... they govern us in all we do, in all we say, in all we think: every effort we can make to throw off our subjection, will serve but to demonstrate and confirm it.

We may scatter the seeds of courtesy and kindness about us at little expense. Some of them will fall on good ground, and grow up into benevolence in the minds of others, and all of them will bear fruit of happiness in the bosom whence they spring.

Those physical difficulties which you cannot account for, be very slow to arraign; for he that would be wiser than Nature would be wiser than God.

Pleasure is in itself a good; nay, even setting aside immunity from pain, the only good.

He who thinks and thinks for himself, will always have a claim to thanks; it is no matter whether it be right or wrong, so as it be explicit. If it is right, it will serve as a guide to direct; if wrong, as a beacon to warn.

Every law is an infraction of liberty.

All poetry is misrepresentation.
