“I didn't arrive at my understanding of the fundamental laws of the universe through my rational mind.”

“Imagination is more important than knowledge”

“I never made one of my discoveries through the process of rational thinking”

“I do not believe in the God of theology who rewards good and punishes evil. My God created laws that take care of that. His universe is not ruled by wishful thinking, but by immutable laws.”

“What can a meaning outside my condition mean to me? I can understand only in human terms. What I touch, what resists me--that is what I understand. And these two certainties--my appetite for the absolute and for unity and the impossibility of reducing this world to a rational and reasonable principle--I also know that I cannot reconcile them. What other truth can I admit without lying, without bringing in a hope which I lack and which means nothing within the limits of my condition?”

“Your question is the most difficult in the world. It is not a question I can answer simply with yes or no. I am not an Atheist. I do not know if I can define myself as a Pantheist. The problem involved is too vast for our limited minds. May I not reply with a parable? The human mind, no matter how highly trained, cannot grasp the universe. We are in the position of a little child, entering a huge library whose walls are covered to the ceiling with books in many different tongues. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written. The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend, but only dimly suspects. That, it seems to me, is the attitude of the human mind, even the greatest and most cultured, toward God. We see a universe marvelously arranged, obeying certain laws, but we understand the laws only dimly. Our limited minds cannot grasp the mysterious force that sways the constellations. I am fascinated by Spinoza's Pantheism. I admire even more his contributions to modern thought. Spinoza is the greatest of modern philosophers, because he is the first philosopher who deals with the soul and the body as one, not as two separate things.”

“I don't pretend to understand the universe — it's much bigger than I am.”
