"The most beautiful thing we can experience is the mysterious. It is the source of all true art and science."

"If A is a success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut"

"Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper."

"The most incomprehensible thing about the world is that it is at all comprehensible."
