Opinions about obviousness are to a certain extent a function of time.

When I'm judging a theory, I ask myself whether, if I were God, I would have arranged the world in such a way.

The problems that exist in this world can not be solved by the level of thinking that created them.

If you want your children to be smart, tell them stories. If you want them to be really smart, tell them more stories. If you want your children to be brilliant, tell them even more stories.

The sceptic will say, 'It may well be true that this system of equations is reasonable from a logical standpoint, but this does not prove that it corresponds to nature.' You are right, dear sceptic. Experience alone can decide on truth.

If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.

What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility. This is a genuinely religious feeling that has nothing to do with mysticism.
