Nothing is miserable but what is thought so, and contrariwise, every estate is happy if he that bears it be content.

Love binds people too, in matrimony's sacred bonds where chaste lovers are met, and friends cement their trust and friendship. How happy is mankind, if the love that orders the stars above rules, too, in your hearts.

Inconsistency is my very essence; it is the game I never cease to play as I turn my wheel in its ever changing circle, filled with joy as I bring the top to the bottom and the bottom to the top

Nothing is miserable unless you think it so; and on the other hand, nothing brings happiness unless you are content with it.

As far as possible, join faith to reason.

The science of numbers ought to be preferred as an acquisition before all others, because of its necessity and because of the great secrets and other mysteries which there are in the properties of numbers. All sciences partake of it, and it has need of none.

Wretched men cringe before tyrants who have no power, the victims of their trivial hopes and fears. They do not realise that anger is hopeless, fear is pointless and desire all a delusion. He whose heart is fickle is not his own master, has thrown away his shield, deserted his post, and he forges the links of the chain that holds him.
