“4. Religion. Your reason is now mature enough to examine this object. In the first place, divest yourself of all bias in favor of novelty & singularity of opinion… shake off all the fears & servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear. You will naturally examine first, the religion of your own country. Read the Bible, then as you would read Livy or Tacitus. The facts which are within the ordinary course of nature, you will believe on the authority of the writer, as you do those of the same kind in Livy and Tacitus. The testimony of the writer weighs in their favor, in one scale, and their not being against the laws of nature, does not weigh against them. But those facts in the Bible which contradict the laws of nature, must be examined with more care, and under a variety of faces. Here you must recur to the pretensions of the writer to inspiration from God. Examine upon what evidence his pretensions are founded, and whether that evidence is so strong, as that its falsehood would be more improbable than a change in the laws of nature, in the case he relates. For example in the book of Joshua we are told the sun stood still several hours. Were we to read that fact in Livy or Tacitus we should class it with their showers of blood, speaking of statues, beasts, &c. But it is said that the writer of that book was inspired. Examine therefore candidly what evidence there is of his having been inspired. The pretension is entitled to your inquiry, because millions believe it. On the other hand you are astronomer enough to know how contrary it is to the law of nature that a body revolving on its axis as the earth does, should have stopped, should not by that sudden stoppage have prostrated animals, trees, buildings, and should after a certain time have resumed its revolution, & that without a second general prostration. Is this arrest of the earth’s motion, or the evidence which affirms it, most within the law of probabilities? You will next read the New Testament. It is the history of a personage called Jesus. Keep in your eye the opposite pretensions: 1, of those who say he was begotten by God, born of a virgin, suspended & reversed the laws of nature at will, & ascended bodily into heaven; and 2, of those who say he was a man of illegitimate birth, of a benevolent heart, enthusiastic mind, who set out without pretensions to divinity, ended in believing them, and was punished capitally for sedition, by being gibbeted, according to the Roman law, which punished the first commission of that offence by whipping, & the second by exile, or death in fureâ….Do not be frightened from this inquiry by any fear of its consequences. If it ends in a belief that there is no God, you will find incitements to virtue in the comfort and pleasantness you feel in its exercise, and the love of others which it will procure you… In fine, I repeat, you must lay aside all prejudice on both sides, and neither believe nor reject anything, because any other persons, or description of persons, have rejected or believed it… I forgot to observe, when speaking of the New Testament, that you should read all the histories of Christ, as well of those whom a council of ecclesiastics have decided for us, to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration, as much as the others, and you are to judge their pretensions by your own reason, and not by the reason of those ecclesiastics. Most of these are lost…[Letter to his nephew, Peter Carr, advising him in matters of religion, 1787]”

“Don’t you believe in flying saucers, they ask me? Don’t you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?No, I reply. No, no, no, no, and again no.One person recently, goaded into desperation by the litany of unrelieved negation, burst out “Don’t you believe in anything?”Yes”, I said. “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.”

“Extraordinary claims require extraordinary evidence.”

“In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore, proportions his belief to the evidence.”

“The search for truth takes you where the evidence leads you, even if, at first, you don’t want to go there.”

“Let’s say that the consensus is that our species, being the higher primates, Homo Sapiens, has been on the planet for at least 100,000 years, maybe more. Francis Collins says maybe 100,000. Richard Dawkins thinks maybe a quarter-of-a-million. I’ll take 100,000. In order to be a Christian, you have to believe that for 98,000 years, our species suffered and died, most of its children dying in childbirth, most other people having a life expectancy of about 25 years, dying of their teeth. Famine, struggle, bitterness, war, suffering, misery, all of that for 98,000 years.Heaven watches this with complete indifference. And then 2000 years ago, thinks ‘That’s enough of that. It’s time to intervene,’ and the best way to do this would be by condemning someone to a human sacrifice somewhere in the less literate parts of the Middle East. Don’t lets appeal to the Chinese, for example, where people can read and study evidence and have a civilization. Let’s go to the desert and have another revelation there. This is nonsense. It can’t be believed by a thinking person.Why am I glad this is the case? To get to the point of the wrongness of Christianity, because I think the teachings of Christianity are immoral. The central one is the most immoral of all, and that is the one of vicarious redemption. You can throw your sins onto somebody else, vulgarly known as scapegoating. In fact, originating as scapegoating in the same area, the same desert. I can pay your debt if I love you. I can serve your term in prison if I love you very much. I can volunteer to do that. I can’t take your sins away, because I can’t abolish your responsibility, and I shouldn’t offer to do so. Your responsibility has to stay with you. There’s no vicarious redemption. There very probably, in fact, is no redemption at all. It’s just a part of wish-thinking, and I don’t think wish-thinking is good for people either.It even manages to pollute the central question, the word I just employed, the most important word of all: the word love, by making love compulsory, by saying you MUST love. You must love your neighbour as yourself, something you can’t actually do. You’ll always fall short, so you can always be found guilty. By saying you must love someone who you also must fear. That’s to say a supreme being, an eternal father, someone of whom you must be afraid, but you must love him, too. If you fail in this duty, you’re again a wretched sinner. This is not mentally or morally or intellectually healthy.And that brings me to the final objection – I’ll condense it, Dr. Orlafsky – which is, this is a totalitarian system. If there was a God who could do these things and demand these things of us, and he was eternal and unchanging, we’d be living under a dictatorship from which there is no appeal, and one that can never change and one that knows our thoughts and can convict us of thought crime, and condemn us to eternal punishment for actions that we are condemned in advance to be taking. All this in the round, and I could say more, it’s an excellent thing that we have absolutely no reason to believe any of it to be true.”

“…What I have denied and what my reason compels me to deny, is the existence of a Being throned above us as a god, directing our mundane affairs in detail, regarding us as individuals, punishing us, rewarding us as human judges might.When the churches learn to take this rational view of things, when they become true schools of ethics and stop teaching fables, they will be more effective than they are to-day… If they would turn all that ability to teaching this one thing – the fact that honesty is best, that selfishness and lies of any sort must surely fail to produce happiness – they would accomplish actual things. Religious faiths and creeds have greatly hampered our development. They have absorbed and wasted some fine intellects. That creeds are getting to be less and less important to the average mind with every passing year is a good sign, I think, although I do not wish to talk about what is commonly called theology.The criticisms which have been hurled at me have not worried me. A man cannot control his beliefs. If he is honest in his frank expression of them, that is all that can in justice be required of him. Professor Thomson and a thousand others do not in the least agree with me. His criticism of me, as I read it, charged that because I doubted the soul’s immortality, or ‘personality,’ as he called it, my mind must be abnormal, ‘pathological,’ in other, words, diseased… I try to say exactly what I honestly believe to be the truth, and more than that no man can do. I honestly believe that creedists have built up a mighty structure of inaccuracy, based, curiously, on those fundamental truths which I, with every honest man, must not alone admit but earnestly acclaim.I have been working on the same lines for many years. I have tried to go as far as possible toward the bottom of each subject I have studied. I have not reached my conclusions through study of traditions; I have reached them through the study of hard fact. I cannot see that unproved theories or sentiment should be permitted to have influence in the building of conviction upon matters so important. Science proves its theories or it rejects them. I have never seen the slightest scientific proof of the religious theories of heaven and hell, of future life for individuals, or of a personal God. I earnestly believe that I am right; I cannot help believing as I do… I cannot accept as final any theory which is not provable. The theories of the theologians cannot be proved. Proof, proof! That is what I always have been after; that is what my mind requires before it can accept a theory as fact. Some things are provable, some things disprovable, some things are doubtful. All the problems which perplex us, now, will, soon or late, be solved, and solved beyond a question through scientific investigation. The thing which most impresses me about theology is that it does not seem to be investigating. It seems to be asserting, merely, without actual study….Moral teaching is the thing we need most in this world, and many of these men could be great moral teachers if they would but give their whole time to it, and to scientific search for the rock-bottom truth, instead of wasting it upon expounding theories of theology which are not in the first place firmly based. What we need is search for fundamentals, not reiteration of traditions born in days when men knew even less than we do now.[Columbian Magazine interview]”

“We all know that any emotional bias — irrespective of truth or falsity — can be implanted by suggestion in the emotions of the young, hence the inherited traditions of an orthodox community are absolutely without evidential value…. If religion were true, its followers would not try to bludgeon their young into an artificial conformity; but would merely insist on their unbending quest for truth, irrespective of artificial backgrounds or practical consequences. With such an honest and inflexible openness to evidence, they could not fail to receive any real truth which might be manifesting itself around them. The fact that religionists do not follow this honourable course, but cheat at their game by invoking juvenile quasi-hypnosis, is enough to destroy their pretensions in my eyes even if their absurdity were not manifest in every other direction.”

“I’m frequently asked, “Do you believe there’s extraterrestrial intelligence?” I give the standard arguments- there are a lot of places out there, the molecules of life are everywhere, I use the word billions, and so on. Then I say it would be astonishing to me if there weren’t extraterrestrial intelligence, but of course there is as yet no compelling evidence for it.Often, I’m asked next, “What do you really think?”I say, “I just told you what I really think.””Yes, but what’s your gut feeling?”But I try not to think with my gut. If I’m serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble. Really, it’s okay to reserve judgment until the evidence is in.”

“It is debatable whether blind faith is truly faith at all. Faith is the perceptive gray area where scientific facts meet an individual’s experiential truths – the extreme of the former is left feeling in the dark whereas the latter is caught blinded by the light. By proper scientific method, it is intellectually dishonest for me to declare the existence of God with utmost certainty, but to my individual spirit, I would be intellectually dishonest to deny the existence of God even for a second. This leaves the best of both worlds, as the believer is called to be able to give reasons for his faith, a deviation from mere fantasy.”

“I couldn’t care less about evidence and proof and assurances. I just want God. I want God inside me. I want God to play in my bloodstream the way sunlight amuses itself on water.”

“Never judge someone’s character based on the words of another. Instead, study the motives behind the words of the person casting the bad judgment. An honest woman can sell tangerines all day and remain a good person until she dies, but there will always be naysayers who will try to convince you otherwise. Perhaps this woman did not give them something for free, or at a discount. Perhaps too, that she refused to stand with them when they were wrong — or just stood up for something she felt was right. And also, it could be that some bitter women are envious of her, or that she rejected the advances of some very proud men. Always trust your heart. If the Creator stood before a million men with the light of a million lamps, only a few would truly see him because truth is already alive in their hearts. Truth can only be seen by those with truth in them. He who does not have Truth in his heart, will always be blind to her.”

“[E]xceptional claims demand exceptional evidence.”

“We may not yet know the right way to go, but we should at least stop going in the wrong direction.”

“Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all ‘faith’ is grounded. In the words of Pope John Paul II: ‘By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.’ It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this. ‘Faith’ is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. ‘Faith’ is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence.But of course we never apply these lax standards of evidence to the claims made in the other fellow’s holy scriptures: when it comes to religions other than one’s own, religious people are as rational as everyone else. Only our own religion, whatever it may be, seems to merit some special dispensation from the general standards of evidence.And here, it seems to me, is the crux of the conflict between religion and science. Not the religious rejection of specific scientific theories (be it heliocentrism in the 17th century or evolutionary biology today); over time most religions do find some way to make peace with well-established science. Rather, the scientific worldview and the religious worldview come into conflict over a far more fundamental question: namely, what constitutes evidence.Science relies on publicly reproducible sense experience (that is, experiments and observations) combined with rational reflection on those empirical observations. Religious people acknowledge the validity of that method, but then claim to be in the possession of additional methods for obtaining reliable knowledge of factual matters — methods that go beyond the mere assessment of empirical evidence — such as intuition, revelation, or the reliance on sacred texts. But the trouble is this: What good reason do we have to believe that such methods work, in the sense of steering us systematically (even if not invariably) towards true beliefs rather than towards false ones? At least in the domains where we have been able to test these methods — astronomy, geology and history, for instance — they have not proven terribly reliable. Why should we expect them to work any better when we apply them to problems that are even more difficult, such as the fundamental nature of the universe?Last but not least, these non-empirical methods suffer from an insuperable logical problem: What should we do when different people’s intuitions or revelations conflict? How can we know which of the many purportedly sacred texts — whose assertions frequently contradict one another — are in fact sacred?”
