“Unlike him I had been unable to escape into the simple complexities of science. All he had to do was solve the mystery of the universe, which may be difficult but is not as difficult as living an ordinary life...(How happy scientists are! Why didn't we become scientists, Percival? They confront problems which can be solved. We don't know what we confront. Does it have a name?)”

“Why does the universe go to all the bother of existing? Is the unified theory so compelling that it brings about its own existence? Or does it need a creator, and, if so, does he have any other effect on the universe? And who created him?....Up to now, most scientists have been too occupied with the development of new theories that describe what the universe is to ask the question why. On the other hand, the people whose business it is to ask why, the philosophers, have not been able to keep up with the advance of scientific theories....However, if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason--for then we would know the mind of God.”

“We must be willing to fail and to appreciate the truth that often "Life is not a problem to be solved, but a mystery to be lived.”

“A real scientist solves problems, not wails that they are unsolvable.”

“Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.”

“Everybody's a mad scientist, and life is their lab. We're all trying to experiment to find a way to live, to solve problems, to fend off madness and chaos.”
