Poverty is the mother of crime.

Men seek out retreats for themselves in the country, by the seaside, on the moutains . . . But all this is unphilosophical to the last degree . . . when thou canst at a moment's notice retire into thyself.

Dress not thy thoughts in too fine a raiment. And be not a man of superfluous words or superfluous deeds.

Love the little trade which thou hast learned, and be content therewith.

If you are distressed by something, it is due to your own estimate of it; and you have the power to change it at will.

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

If you are pained by any external thing, it is not this that disturbs you, but your own judgment about it.
