“People almost invariably arrive at their beliefs not on the basis of proof but on the basis of what they find attractive.”
“To make light of philosophy is to be a true philosopher.”
“You always admire what you really don't understand.”
“Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed.”
“In difficult times carry something beautiful in your heart.”
“Contradiction is not a sign of falsity, nor the lack of contradiction a sign of truth.”
“Nature is an infinite sphere whose center is everywhere and whose circumference is nowhere.”
“To understand is to forgive.”
“The more I see of Mankind, the more I prefer my dog.”
