“...the only simplicity to be trusted is the simplicity to be found on the far side of complexity.”

“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.”

“Life is complex in its expression, involving more than percipience, namely desire, emotion, will, and feeling.”

“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.”

“We cannot think first and act afterwards. From the moment of birth we are immersed in action and can only guide it by taking thought.”

“The ideas of Freud were popularized by people who only imperfectly understood them, who were incapable of the great effort required to grasp them in their relationship to larger truths, and who therefore assigned to them a prominence out of all proportion to their true importance.”

“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....”
