Faith is not a leap in the dark; it’s the exact opposite. It’s a commitment based on evidence… It is irrational to reduce all faith to blind faith and then subject it to ridicule. That provides a very anti-intellectual and convenient way of avoiding intelligent discussion.

Plainly it is not every error made by a witness which affects his credibility. In each case the trier of fact has to make an evaluation; taking into account such matters as the nature of the contradictions, their number and importance, and their bearing on other parts of the witness's evidence.

Why does Alexander the Great never tell us about the exact location of his tomb, Fermat about his Last Theorem, John Wilkes Booth about the Lincoln assassination conspiracy, Hermann Göring about the Reichstag fire? Why don’t Sophocles, Democritus, and Aristarchus dictate their lost books?

Mathematics had never had more than a secondary interest for him [her husband, George Boole]; and even logic he cared for chiefly as a means of clearing the ground of doctrines imagined to be proved, by showing that the evidence on which they were supposed to give rest had no tendency to prove them.

The difference between my beliefs and having a religious faith is that I am prepared to change my views in light of new evidence, but someone of a religious faith will just stick their fingers in the ears and say: 'I'm not listening, there's nothing you can say that will make me change my mind.

I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.

Today the earth speaks with resonance and clearness and every ear in every civilized country of the world is attuned to its wonderful message of the creative evolution of man, except the ear of William Jennings Bryan; he alone remains stone-deaf, he alone by his own resounding voice drowns the eternal speech of nature.

Mere lack of evidence, of course, is no reason to denounce a theory. Look at intelligent design. The fact that it is bollocks hasn’t stopped a good many people from believing in it. Darwinism itself is only supported by tons of evidence, which is a clear indication that Darwin didn’t write his books himself.

They do not like evidence like that, anything too definite because our first instinct is to find flaws and debunk. They want to be discussed and portrayed, but never proven. They want to be credited as the true makers of the pyramids and lifters of Stonehenge when it had much more to do with the gods who were then extant.

Another of Mack’s patients says that the aliens have been taking eggs from her since she was sexually mature, and that her reproductive system baffles her gynecologist. Is it baffling enough to write the case up and submit a research paper to The New England Journal of Medicine? Apparently it’s not that baffling.

If in some radical miracle, the Abrahamic God revealed his existence to the world, I’d accept the belief in the deity — but I still wouldn't worship it. The jealous and angry God that justified the killings of millions, sent plagues upon first borns, and abhorred homosexuals would not be worthy of my worship.

It's natural to think that living things must be the handiwork of a designer. But it was also natural to think that the sun went around the earth. Overcoming naive impressions to figure out how things really work is one of humanity's highest callings.[Can You Believe in God and Evolution? Time Magazine, August 7, 2005]

The evolution of life, and the evolutionary origin of mankind, are scientifically established as firmly and completely as any historical event not witnessed by human observers. Any concession to anti-evolutionists, suggesting that there are scientific reasons to doubt the facticity of evolution, would be propagating a plain untruth.

The atom can't be seen, yet its existence can be proved. And it is simple to prove that it can't ever be seen. It has to be studied by indirect evidence — and the technical difficulty has been compared to asking a man who has never seen a piano to describe a piano from the sound it would make falling downstairs in the dark.

Scientists gladly accept any new truth demonstrated by evidence, that is, proved by the very law of the cosmos. Not so with any new conceptions of religion; these are fought by the use of persecution and venom. Many of the current religious beliefs literally carried into practice would stampede humanity into the old jungle ideas and habits.
