The two principles of truth, reason and senses, are not only both not genuine, but are engaged in mutual deception. The senses deceive reason through false appearances, and the senses are disturbed by passions, which produce false impressions.
Blaise PascalThe least movement is of importance to all nature. The entire ocean is affected by a pebble.
Blaise PascalOne-half of life is admitted by us to be passed in sleep, in which, however, it may appear otherwise, we have no perception of truth, and all our feelings are delusions; who knows but the other half of life, in which we think we are awake, is a sleep also, but in some respects different from the other, and from which we wake when we, as we call it, sleep. As a man dreams often that he is dreaming, crowding one dreamy delusion on another.
