1 " [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.[From various of Whitehead's books, not only PR] "
2 " ...on a number of occasions this book has made reference to magic, and each time you've shaken your head, muttering such criticisms as " What does he mean by 'magic' anyhow? It's embarrassing to find a grown man talking about magic in such a manner. How can anybody take him seriously?" Or, as slightly more gracious readers have objected, " Doesn't the author realize that one can't write about magic? One can create it but not discuss it. It's much too gossamer for that. Magic can be neither described nor defined. Using words to describe magic is like using a screwdriver to slice roast beef." To which the author now replies, Sorry, freeloaders, you're clever but you're not quite correct. Magic isn't the fuzzy, fragile, abstract and ephemeral quality you think it is. In fact, magic is distinguished from mysticism by its very concreteness and practicality. Whereas mysticism is manifest only in spiritual essence, in the transcendental state, magic demands a steady naturalistic base. Mysticism reveals the ethereal in the tangible. Magic makes something permanent out of the transitory, coaxes drama from the colloquial. "
3 " Einstein, twenty-six years old, only three years away from crude privation, still a patent examiner, published in the Annalen der Physik in 1905 five papers on entirely different subjects. Three of them were among the greatest in the history of physics. One, very simple, gave the quantum explanation of the photoelectric effect—it was this work for which, sixteen years later, he was awarded the Nobel prize. Another dealt with the phenomenon of Brownian motion, the apparently erratic movement of tiny particles suspended in a liquid: Einstein showed that these movements satisfied a clear statistical law. This was like a conjuring trick, easy when explained: before it, decent scientists could still doubt the concrete existence of atoms and molecules: this paper was as near to a direct proof of their concreteness as a theoretician could give. The third paper was the special theory of relativity, which quietly amalgamated space, time, and matter into one fundamental unity. This last paper contains no references and quotes to authority. All of them are written in a style unlike any other theoretical physicist's. They contain very little mathematics. There is a good deal of verbal commentary. The conclusions, the bizarre conclusions, emerge as though with the greatest of ease: the reasoning is unbreakable. It looks as though he had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done. "
