We are only troubled by the fears which we, and not nature, give ourselves, for they add to the state in which we are the passions of the state in which we are not.
Blaise PascalHuman life is thus only a perpetual illusion; men deceive and flatter each other. No one speaks of us in our presence as he does of us in our absence. Human society is founded on mutual deceit; few friendships would endure if each knew what his friend said of him in his absence, although he then spoke in sincerity and without passion.
Blaise Pascal
