While you live, while it is in your power, be good.

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

At day's first light have in readiness, against disinclination to leave your bed, the thought that "I am rising for the work of man."

If souls continue to exist, how does the air contain them from eternity?

Doctors keep their scalpels and other instruments handy, for emergencies. Keep your philosophy ready too - ready to understand heaven and earth. In everything you do, even the smallest thing, remember the chain that links them. Nothing earthly succeeds by ignoring heaven, nothing heavenly by ignoring earth.

Very little is needed to make a happy life; it is all within yourself, in your way of thinking.

Pass then through this little space of time conformably to nature, and end thy journey in content, just as an olive falls off when it is ripe, blessing nature who produced it, and thanking the tree on which it grew.
