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 PascalEvil is easily discovered; there is an infinite variety; good is almost unique. But some kinds of evil are almost as difficult to discover as that which we call good; and often particular evil of this class passes for good. It needs even a certain greatness of soul to attain to this, as to that which is good.
Blaise Pascal
