Realization is… in itself the attainment of value - Alfred North Whitehead

Thus nature gets credit which should in truth be reserved for ourselves: the rose for its scent: the nightingale for his song: the sun for its radiance. The poets are entirely mistaken. They should address their lyrics to themselves, and should turn them into odes of self-congratulation on the excellency of the human mind. Nature is a dull affair, soundless, scentless, colourless...

Life is an offensive directed against the repetitious mechanism of the universe.

"[Beware of] the fallacy of misplaced concreteness [mistaking an abstraction for concrete reality, for actuality]

In the inescapable flux, there is something that abides; in the overwhelming permanence, there is an element that escapes into flux. Permanence can be snatched only out of flux; and the passing moment can find its adequate intensity only by its submission to permanence.

Error is the price we pay for progress.

In the real world it is more important that a proposition be interesting than that it be true. The importance of truth is that it adds to interest.

Creativity is the universal of universals characterizing ultimate matter of fact. It is that ultimate principle by which the many, which are the universe disjunctively, become the one actual occasion, which is the universe conjunctively. It lies in the nature of things that the many enter into complex unity.

The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

It requires a very unusual mind to undertake the analysis of the obvious.
