“The clothes have no emperor.”

“Beliefs are personal, but universal truths are above that. For example, the surface temperature of the sun is around 5,505 degrees Celsius – the speed of light is around 300,000 kilometers per second – the Earth is about 4.5 billion years old – modern day chimps are the closest cousins of us humans. These are irrefutable universal truth, regardless of what anyone believes.”

“Science is what we have learned about how to keep from fooling ourselves.”

“All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.”

“Now it is such a bizarrely improbable coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God.The argument goes something like this: “I refuse to prove that I exist,'” says God, “for proof denies faith, and without faith I am nothing.””But,” says Man, “The Babel fish is a dead giveaway, isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. QED.””Oh dear,” says God, “I hadn’t thought of that,” and promptly vanishes in a puff of logic.”Oh, that was easy,” says Man, and for an encore goes on to prove that black is white and gets himself killed on the next zebra crossing.”

“I long for the slightest evidence of it that doesn’t require me to relinquish reason, because a natural mystery and reason to face it make the happiest combination of all.”

“Let’s say I have a mystical soul and a rational brain, and, like Montaigne, I am incapable of choosing between them. I don’t know if I believe in God, but I am often tempted to believe.”

“If we wanted to construct a basic philosophical attitude from these scientific utterances of Pauli’s, at first we would be inclined to infer from them an extreme rationalism and a fundamentally skeptical point of view. In reality however, behind this outward display of criticism and skepticism lay concealed a deep philosophical interest even in those dark areas of reality of the human mind which elude the grasp of reason. And while the power of fascination emanating from Pauli’s analyses of physical problems was admittedly due in some measure to the detailed and penetrating clarity of his formulations, the rest was derived from a constant contact with the field of creative processes, for which no rational formulation as yet exists.”

“See the exquisite contrast of the types of mind! The pragmatist clings to facts and concreteness, observes truth at its work in particular cases, and generalises. Truth, for him, becomes a class-name for all sorts of definite working-values in experience. For the rationalist it remains a pure abstraction, to the bare name of which we must defer. When the pragmatist undertakes to show in detail just why we must defer, the rationalist is unable to recognise the concretes from which his own abstraction is taken. He accuses us of denying truth; whereas we have only sought to trace exactly why people follow it and always ought to follow it. Your typical ultra-abstractions fairly shudders at concreteness: other things equal, he positively prefers the pale and spectral. If the two universes were offered, he would always choose the skinny outline rather than the rich thicket of reality. It is so much purer, clearer, nobler.”

“A concept is a brick. It can be used to build a courthouse of reason. Or it can be thrown through the window.”
