For in all adversity of fortune the worst sort of misery is to have been happy.

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

Nunc fluens facit tempus,nunc stans facit aeternitatum.(The now that passes produces time, the now that remains produces eternity.)

A man content to go to heaven alone will never go to heaven.

He who is virtuous is wise; and he who is wise is good; and he who is good is happy.

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.

He who has calmly reconciled his life to fate ... can look fortune in the face.
