“We are supernaturalists first, not naturalists. The only reason we feel compelled to accommodate science is that science says we ought to. But it is science that should accommodate revelation. Revelation has been around much longer.”

“There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art. Neither is independent of the other or more important than the other. Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from becoming ridiculous.”(Great Thought, February 19, 1938)”

“And I find a happiness in the fact of accepting —In the sublimely scientific and difficult fact of accepting the inevitable natural.”

“It is the natural tendency of the ignorant to believe what is not true. In order to overcome that tendency it is not sufficient to exhibit the true; it is also necessary to expose and denounce the false. To admit that the false has any standing in court, that it ought to be handled gently because millions of morons cherish it and thousands of quacks make their livings propagating it—to admit this, as the more fatuous of the reconcilers of science and religion inevitably do, is to abandon a just cause to its enemies, cravenly and without excuse.”

“Temporis filia veritas; cui me obstetricari non pudet.Truth is the daughter of time, and I feel no shame in being her midwife.”

“To say that the first casualty of war is truth is to miss the rather more important point that a principal weapon of war is lies.”

“A man craves ultimate truths. Every mortal mind, I think, is that way. But what is ultimate truth? It’s the end of the road, where there is no more mystery, no more hope. And no more questions to ask, since all the answers have been given. But there is no such place.The Universe is a labyrinth made of labyrinths. Each leads to another. And wherever we cannot go ourselves, we reach with mathematics. Out of mathematics we build wagons to carry us into the nonhuman realms of the world.”

“It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them.”

“Numbers do not feel. Do not bleed or weep or hope. They do not know bravery or sacrifice. Love and allegiance. At the very apex of callousness, you will find only ones and zeros.”

“The scientist only imposes two things, namely truth and sincerity, imposes them upon himself and upon other scientists.”

“So those who wished for some central cosmic purpose for us, or at least our world, or at least our solar system, or at least our galaxy, have been disappointed, progressively disappointed. The universe is not responsive to our ambitious expectations.”

“In practical life we are compelled to follow what is most probable ; in speculative thought we are compelled to follow truth.”

“A new concept of god: “something not very different from the sum total of the physical laws of the universe; that is, gravitation plus quantum mechanics plus grand unified field theories plus a few other things equaled god. And by that all they meant was that here were a set of exquisitely powerful physical principles that seemed to explain a great deal that was otherwise inexplicable about the universe. Laws of nature…that apply not just locally, not just in Glasgow, but far beyond: Edinburgh, Moscow…Mars…the center of the Milky Way, and out by the most distant quarters known. That the same laws of physics apply everywhere is quite remarkable. Certainly that represents a power greater than any of us.”

“The essence of science is that it is always willing to abandon a given idea for a better one; the essence of theology is that it holds its truths to be eternal and immutable.”

“See now the power of truth; the same experiment which at first glance seemed to show one thing, when more carefully examined, assures us of the contrary.”
