I don’t believe in conspiracy theories. I’m just a cold-blooded investigator.

A young man who wishes to remain a sound atheist cannot be too careful of his reading.

I don’t believe it. Prove it to me and I still won’t believe it.

I’m skeptical of any mission that has advertisers at its centerpiece.

I personally never expected anything of Obama, and wrote about it before the 2008 primaries. I thought it was smoke and mirrors.

I’m an atheist.

I read the NY Times but I don’t trust all of it.

I know that the arts are important. I’m not denying that, but I can’t associate myself with all the claptrap that goes on around it.

The natural cause of the human mind is certainly from credulity to skepticism.

I don’t believe in astrology; I’m a Sagittarius and we’re skeptical.

There is no rule more invariable than that we are paid for our suspicions by finding what we suspect.

Of course you can’t ‚trust‘ what people tell you on the web anymore than you can ‚trust‘ what people tell you on megaphones, postcards or in restaurants. Working out the social politics of who you can trust and why is, quite literally, what a very large part of our brain has evolved to do.

The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd.

Base souls have no faith in great individuals.

Suspicion is far more to be wrong than right; more often unjust than just. It is no friend to virtue, and always an enemy to happiness.

The cynics are right nine times out of ten.

We are always paid for our suspicion by finding what we suspect.

It is always better to have no ideas than false ones; to believe nothing, than to believe what is wrong.

All men having power ought to be distrusted to a certain degree.

All in all, I just don’t trust journalists – and I don’t think it’s a good practice for me to trust journalists.

Premature certainty is the enemy of the truth.

Seeing is not always believing.

No man ever quite believes in any other man. One may believe in an idea absolutely, but not in a man.

Quacks are a part of our culture, and we all fall prey to them. Who among us can say, for sure, that even our own personal physicians are honest and competent?

All formal dogmatic religions are fallacious and must never be accepted by self-respecting persons as final.

Trust, but verify.

I think we ought always to entertain our opinions with some measure of doubt. I shouldn’t wish people dogmatically to believe any philosophy, not even mine.

So near is falsehood to truth that a wise man would do well not to trust himself on the narrow edge.

Isn’t it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?

The dangers of not thinking clearly are much greater now than ever before. It’s not that there’s something new in our way of thinking – it’s that credulous and confused thinking can be much more lethal in ways it was never before.

I don’t easily fall for lies, I can see through things.

You can’t trust very many people.

Yeah, it’s pretty hard not to be completely cynical these days.

I believe there is something out there watching us. Unfortunately, it’s the government.

I don’t consider myself to be that credulous.

Every person who has mastered a profession is a skeptic concerning it.

I trust Russia and China and Iran and North Korea like I trust a Jussie Smollett police report.

People love conspiracy theories.

It is wrong always, everywhere, and for everyone, to believe anything upon insufficient evidence.

Nothing fortifies scepticism more than the fact that there are some who are not sceptics; if all were so, they would be wrong.

I don’t believe in icons.

I haven’t trusted polls since I read that 62% of women had affairs during their lunch hour. I’ve never met a woman in my life who would give up lunch for sex.

I don’t believe in the after life, although I am bringing a change of underwear.

The greatest achievements of the human mind are generally received with distrust.

Whoever feels predestined to see and not to believe will find all believers too noisy and pushy: he guards against them.

I would love to encourage all my teammates to eat the best way they possibly can. High school athletes. Now, that’s not the way our food system in America is set up. It’s very different. They have a food pyramid, and I disagree with that. I disagree with a lot of things that people tell you to do.

Nevertheless, it is even harder for the average ape to believe that he has descended from man.

Nothing is more dangerous to one’s own faith than the work of an apologist. No doctrine of that faith seems to me so spectral, so unreal as one that I have just successfully defended in a public debate.

Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along and say how stupid we were.

I purposely don’t talk about money, because people are already skeptical about TV preachers. But I do say that I want you to be blessed. To me, prosperity is having health, having great children, having peace, good relationships. It’s not about the money.

If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong.

The word ‚belief‘ is a difficult thing for me. I don’t believe. I must have a reason for a certain hypothesis. Either I know a thing, and then I know it – I don’t need to believe it.

When I meet people who say – which they do all of the time – ‚I must just tell you, my great aunt had cancer of the elbow and the doctors gave her 10 seconds to live, but last I heard she was climbing Mount Everest,‘ and so forth, I switch off quite early.

I really don’t believe in magic.

People are skeptical of many televangelists, and I’m sensitive to that.

The world embarrasses me, and I cannot dream that this watch exists and has no watchmaker.

The root of all superstition is that men observe when a thing hits, but not when it misses.

I have written too much history to have faith in it; and if anyone thinks I’m wrong, I am inclined to agree with him.

I’m a strict, strict agnostic. It’s very different from a casual, ‚I don’t know.‘ It’s that you cannot present as knowledge something that is not knowledge. You can present it as faith, you can present it as belief, but you can’t present it as fact.

A lot of people, because of my contempt for the false consolations of religion, think of me as a symbolic public opponent of that in extremis. And sometimes that makes me feel a bit alarmed, to be the repository of other people’s hope.

It is dangerous to be right in matters on which the established authorities are wrong.
