“No, our science is no illusion. But an illusion it would be to suppose that what science cannot give us we can get elsewhere.”

“Science promised us truth, or at least a knowledge of such relations as our intelligence can seize: it never promised us peace or happiness. Sovereignly indifferent to our feelings, it is deaf to our lamentations. It is for us to endeavour to live with science, since nothing can bring back the illusions it has destroyed”

“We believe that it is possible for scientific work to gain some knowledge about the reality of the world, by means of which we can increase out power and in accordance with which we can arrange our life. If this belief is an illusion, then we are in the same position as you. But science has given us evidence by its numerous and important successes that it is no illusion.”

“But now science is the belief system that is hundreds of years old. And, like the medieval system before it, science is starting not to fit the world any more. Science has attained so much power that its practical limits begin to be apparent. Largely through science, billions of us live in one small world, densely packed and intercommunicating. But science cannot help us decide what to do with that world, or how to live. Science can make a nuclear reactor, but it cannot tell us not to build it. Science can make pesticide, but cannot tell us not to use it. And our world starts to seem polluted in fundamental ways---air, and water, and land---because of ungovernable science.”

“For what we suppose to be our love or our jealousy is never a single, continuous and indivisible passion. It is composed of an infinity of successive loves, of different jealousies, each of which is ephemeral, although by their uninterrupted multiplicity they give us the impression of continuity, the illusion of unity.”

“I believe in rendering to science the things that belong to science. I have no problem with evolution or discussions of the age of the Earth, for I don't believe that we come anywhere near comprehending the mind of God or the workings of the universe. Science can explain a lot, but it cannot give us faith, and I think we need both.”
