Don't be afraid to say what you are not afraid to think

The share we have in the knowledge of truth, such as it is, has not been acquired by our own powers. God has taught ushis wonderful secrets; our faith is not of our acquiring, it is purely the gift of another's bounty.

Arts and sciences are not cast in a mould, but are found and perfected by degrees, by often handling and polishing.

A wise man never loses anything, if he has himself.

Not because Socrates said so, but because it is in truth my own disposition — and perchance to some excess — I look upon all men as my compatriots, and embrace a Pole as a Frenchman, making less account of the national than of the universal and common bond.

Nobody is exempt from saying stupid things, the harm is to do it presumptuously.

Those sciences which govern the morals of mankind, such as Theology and Philosophy, make everything their concern: no activity is so private or so secret as to escape their attention or their jurisdiction.
