“When you are criticizing the philosophy of an epoch, do not chiefly direct your attention to those intellectual positions which its exponents feel it necessary explicitly to defend. There will be some fundamental assumptions which adherents to all the variant systems within the epoch unconsciously presuppose. Such assumptions appear so obvious that people do not know what they are assuming because no other way of putting things has ever occurred to them. With these assumptions a certain limited number of types of philosophic systems are possible, and this group of systems constitutes the philosophy of the epoch.”

“The truth is that science started its modern career by taking over ideas derived from the weakest side of the philosophies of Aristotle's successors. In some respects it was a happy choice. It enabled the knowledge of the seventeenth century to be formularised so far as physics and chemistry were concerned, with a completeness which has lasted to the present time. But the progress of biology and psychology has probably been checked by the uncritical assumption of half-truths. If science is not to degenerate into a medley of ad hoc hypothesis, it must become philosophical and must enter upon a thorough criticism of its own foundations.”

“Philosophy is a necessary activity because we, all of us, take a great number of things for granted, and many of these assumptions are of a philosophical character; we act on them in private life, in politics, in our work, and in every other sphere of our lives -- but while some of these assumptions are no doubt true, it is likely, that more are false and some are harmful. So the critical examination of our presuppositions -- which is a philosophical activity -- is morally as well as intellectually important.”

“Philosophy begins in wonder. And at the end when philosophic thought has done its best the wonder remains.”

“Religion carries two sorts of people in two entirely opposite directions: the mild and gentle people it carries towards mercy and justice; the persecuting people it carries into fiendish sadistic cruelty. Mind you, though this may seem to justify the eighteenth-century Age of Reason in its contention that religion is nothing but an organized, gigantic fraud and a curse to the human race, nothing could be farther from the truth. It possesses these two aspects, the evil one of the two appealing to people capable of naïve hatred; but what is actually happening is that when you get natures stirred to their depths over questions which they feel to be overwhelmingly vital, you get the bad stirred up in them as well as the good; the mud as well as the water. It doesn't seem to matter much which sect you have, for both types occur in all sects....”

“Rightness of limitation is essential for growth of reality.Unlimited possibility and abstract creativity can procure nothing. The limitation, and the basis arising from what is already actual, are both of them necessary and interconnected.”

“It is a profoundly erroneous truism that we should cultivate the habit of thinking of what we are doing. The precise opposite is the case. Civilization advances by extending the number of important operations which we can perform without thinking about them.”
