As a start, let me quote something
"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 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 truly know the mind of God."
(Stephen W. Hawking, A Brief History of Time, 1988)
