Nature has placed mankind under the government of two sovereign masters, pain and pleasure.

The question is not can animals speak but can they suffer.

It is with government as with medicine, its only business is the choice of evils. Every law is an evil, for every law is an infraction of liberty.

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.

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.

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

All poetry is misrepresentation.
