Blaise Pascal

"The heart has its reasons which reason knows not."

"All of humanity's problems stem from man's inability to sit quietly in a room alone."

"We know the truth, not only by the reason, but also by the heart."

"Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed."

"Kind words do not cost much. Yet they accomplish much."
