No science can be more secure than the unconscious metaphysics which tacitly it presupposes.

Problems are only opportunities in disquise.

To see what is general in what is particular, and what is permanent in what is transitory, is the aim of scientific thought.

I am also greatly indebted to Bergson, William James, and John Dewey. One of my preoccupations has been to rescue their type of thought from the charge of anti-intellectualism, which rightly or wrongly has been associated with it.

The teleology of the Universe is directed to the production of Beauty... The type of Truth required for the final stretch of Beauty is a discovery and not a recapitulation... Apart from Beauty, Truth is neither good, nor bad... Truth matters because of beauty.

Mathematics as a science, commenced when first someone, probably a Greek, proved propositions about "any" things or about "some" things, without specifications of definite particular things.

An enormous part of our mature experience cannot not be expressed in words.
