Furnished as all Europe now is with Academies of Science, with nice instruments and the spirit of experiment, the progress of human knowledge will be rapid and discoveries made of which we have at present no conception. I begin to be almost sorry I was born so soon, since I cannot have the happiness of knowing what will be known a hundred years hence.

You and I were long friends: you are now my enemy, and I am yours.

You will see in this my notion of good works, that I am far from expecting to merit heaven by them. By heaven we understand a state of happiness, infinite in degree, and eternal in duration. I can do nothing to deserve such rewards... Even the mixed imperfect pleasures we enjoy in this world, are rather from God's goodness than our merit, how much more such happiness of heaven!

The securest place is a prison cell, but there is no liberty

He that blows the coals in quarrels that he has nothing to do with, has no right to complain if the sparks fly in his face. - Ben Franklin

He who multiplies riches multiplies cares.

Beware of the young doctor and the old barber.
