[When thinking about the new relativity and quantum theories] I have felt a homesickness for the paths of physical science where there are ore or less discernible handrails to keep us from the worst morasses of foolishness.

The idea of a universal mind or Logos would be, I think, a fairly plausible inference from the present state of scientific theory.

So far as physics is concerned, time's arrow is a property of entropy alone.

It is also a good rule not to put overmuch confidence in the observational results that are put forward until they are confirmed by theory.

In any attempt to bridge the domains of experience belonging to the spiritual and physical sides of nature, time occupies the key position.

Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers. If you look at the results which science has brought in its train, you will find them to consist almost wholly in elements of mischief. See how much belongs to the word "Explosion" alone, of which the ancients knew nothing.

Whether in the intellectual pursuits of science or in the mystical pursuits of the spirit, the light beckons ahead, and the purpose surging in our nature responds.
