It is a sin to persue pleasure as a good and to avoid pain as a evil.

Let it be your constant method to look into the design of people's actions, and see what they would be at, as often as it is practicable; and to make this custom the more significant, practice it first upon yourself.

No one can keep you from living as your nature requires. Nothings can happen to you that is not required by Nature.

Live not as though there were a thousand years ahead of you. Fate is at your elbow; make yourself good while life and power are still yours.

Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.

Everything is mere opinion.

The substance of the universe is obedient and compliant; and the reason which governs it has in itself no cause for doing evil, for it has no malice, nor does it do evil to anything, nor is anything harmed by it. But all things are made and perfected according to this reason.
