Someone with a fresh mind, one not conditioned by upbringing and environment, would doubtless look at science and the powerful reductionism that it inspires as overwhelmingly the better mode of understanding the world, and would doubtless scorn religion as sentimental wishful thinking. Would not that same uncluttered mind also see the attempts to reconcile science and religion by disparaging the reduction of the complex to the simple as attempts guided by muddle-headed sentiment and intellectually dishonest emotion?...Religion closes off the central questions of existence by attempting to dissuade us from further enquiry by asserting that we cannot ever hope to comprehend. We are, religion asserts, simply too puny. Through fear of being shown to be vacuous, religion denies the awesome power of human comprehension. It seeks to thwart, by encouraging awe in things unseen, the disclosure of the emptiness of faith. Religion, in contrast to science, deploys the repugnant view that the world is too big for our understanding. Science, in contrast to religion, opens up the great questions of being to rational discussion, to discussion with the prospect of resolution and elucidation. Science, above all, respects the power of the human intellect. Science is the apotheosis of the intellect and the consummation of the Renaissance. Science respects more deeply the potential of humanity than religion ever can.

As a convinced atheist, I ought to agree with Voltaire that Judaism is not just one more religion, but in its way the root of religious evil. Without the stern, joyless rabbis and their 613 dour prohibitions, we might have avoided the whole nightmare of the Old Testament, and the brutal, crude wrenching of that into prophecy-derived Christianity, and the later plagiarism and mutation of Judaism and Christianity into the various rival forms of Islam. Much of the time, I do concur with Voltaire, but not without acknowledging that Judaism is dialectical. There is, after all, a specifically Jewish version of the eighteenth-century Enlightenment, with a specifically Jewish name—the Haskalah—for itself. The term derives from the word for 'mind' or 'intellect,' and it is naturally associated with ethics rather than rituals, life rather than prohibitions, and assimilation over 'exile' or 'return.' It's everlastingly linked to the name of the great German teacher Moses Mendelssohn, one of those conspicuous Jewish hunchbacks who so upset and embarrassed Isaiah Berlin. (The other way to upset or embarrass Berlin, I found, was to mention that he himself was a cousin of Menachem Schneerson, the 'messianic' Lubavitcher rebbe.) However, even pre-enlightenment Judaism forces its adherents to study and think, it reluctantly teaches them what others think, and it may even teach them how to think also.

The new atheists show a disturbing lack of understanding of or concern about the complexity and ambiguity of modern experience, and their polemic entirely fails to mention the concern for justice and compassion that, despite their undeniable failings, has been espoused by all three of the monotheisms. Religious fundamentalists also develop an exagerrated view of their enemy as the epitome of evil. This tendency makes critique of the new atheists too easy. They never discuss the work of such theologians as Bultmann or Tillich, who offer a very different view of religion and are closer to mainstream tradition than any fundamentalist. Unlike Feurerbach, Marx and Freud, the new atheists are not theologically literate. As one of their critics has remarked, in any military strategy it is essential to confront the enemy at its strongest point; failure to do so means that their polemic remains shallow and lacks intellectual depth. It is also morally and intellectually conservative. Unlike Feurerback, Marx, Ingersoll or Mill, these new Atheists show little concern about the poverty, injustice and humiliation that has inspired many of the atrocities they deplore; they show no yearning for a better world. Nor, like Nietzsche , Sartre or Camus, do they compel their readers to face up to the pointlessness and futility that ensue when people lack the resources to create a sense of meaning. They do not appear to consider the effect of such nihilism on people who do not have privileged lives and absorbing work.

I think I have a very good idea why it is that anti-Semitism is so tenacious and so protean and so enduring. Christianity and Islam, theistic though they may claim to be, are both based on the fetishizing of human primates: Jesus in one case and Mohammed in the other. Neither of these figures can be called exactly historical but both have one thing in common even in their quasi-mythical dimension. Both of them were first encountered by the Jews. And the Jews, ravenous as they were for any sign of the long-sought Messiah, were not taken in by either of these two pretenders, or not in large numbers or not for long.If you meet a devout Christian or a believing Muslim, you are meeting someone who would give everything he owned for a personal, face-to-face meeting with the blessed founder or prophet. But in the visage of the Jew, such ardent believers encounter the very figure who did have such a precious moment, and who spurned the opportunity and turned shrugging aside. Do you imagine for a microsecond that such a vile, churlish transgression will ever be forgiven? I myself certainly hope that it will not. The Jews have seen through Jesus and Mohammed. In retrospect, many of them have also seen through the mythical, primitive, and cruel figures of Abraham and Moses. Nearer to our own time, in the bitter combats over the work of Marx and Freud and Einstein, Jewish participants and protagonists have not been the least noticeable. May this always be the case, whenever any human primate sets up, or is set up by others, as a Messiah.

Christians don't think that Dawkins thinks that they think that God really has a beard. "Old man in the sky with a white beard" is a figure of speech – shorthand – which neatly encapsulates various errors which lazy atheists and naive theists sometimes make, for example: 1: They imagine that Christians think that God is a human being of some kind and therefore ask questions like: "What does he eat?"; "If he made the world, what did he stand on?"; "If he doesn't have a beard, how does he shave?" and "How did he evolve?" (Three guesses which of those questions troubles Professor Dawkins.) Christians don't think that God is an old man. They don't even think he is a man. They probably don't even think he's made of atoms. 2: They confuse symbols with representations: they think that when Michelangelo painted God on the Pope's ceiling, he was making an informed guess about what someone would have seen with their eyes if they bumped into God on the Roman metro – as opposed to using pictures to put across theological ideas. 3: They imagine that Christians think that God lives in some particular place in space and time. They may not think that we think that he lives in the sky, but I think that they think that we think that if you had a fast enough spaceship you could eventually track him down. Dawkins doesn't commit himself on the question of God's facial hair; but it is pretty clear that he thinks that God lives in the sky – or at any rate, in some place in the empirical universe.

Take the Holocaust for example: Why did God allow Hitler to kill millions of innocent Jews? Because God didn't want to step on Hitler's toes and interfere with his free will? That's a pretty lame excuse. What about the free will of all those Jews who died? I'm pretty sure that getting gassed to death was obviously not their choice. So, was the Holocaust part of God's great plan? Is that why he allowed it to happen? Is that why God didn't answer the prayers of all those Jews who begged him to make Hitler drop dead? Why didn't God just make Hitler have a heart attack before he could start World War 2? Why didn't he simply prevent Hitler from being born? How could a God who is supposed to be all good all the time allow something like the Holocaust?Or did God not just LET it happen? Maybe God MADE the Holocaust happen, because everything that happens, happens for a good reason? Are our minds simply too tiny, too inferior, to understand God's divine plan? Are we just too stupid to see the greater good that came out of the Holocaust?If that were true, and everything that happens, including the Holocaust, is part of God's perfect plan, then that means that Hitler really wasn't a bad man at all. He was actually doing God's work. And if Hitler did exactly what he was supposed to do in God's great plan, then Hitler obviously didn't have free will, but was just God's puppet. So that means Hitler was a good guy. A man of God.Sorry, but there is no religion in the world that could sell me on believing THAT bullshit.

Until I was twenty I was sure there was a being who could see everything I did and who didn't like most of it. He seemed to care about minute aspects of my life, like on what day of the week I ate a piece of meat. And yet, he let earthquakes and mudslides take out whole communities, apparently ignoring the saints among them who ate their meat on the assigned days. Eventually, I realized that I didn't believe there was such a being. It didn't seem reasonable. And I assumed that I was an atheist.As I understood the word, it meant that I was someone who didn't believe in a God; I was without a God. I didn't broadcast this in public because I noticed that people who do believe in a god get upset to hear that others don't. (Why this is so is one of the most pressing of human questions, and I wish a few of the bright people in this conversation would try to answer it through research.)But, slowly I realized that in the popular mind the word atheist was coming to mean something more - a statement that there couldn't be a God. God was, in this formulation, not possible, and this was something that could be proved. But I had been changed by eleven years of interviewing six or seven hundred scientists around the world on the television program Scientific American Frontiers. And that change was reflected in how I would now identify myself.The most striking thing about the scientists I met was their complete dedication to evidence. It reminded me of the wonderfully plainspoken words of Richard Feynman who felt it was better not to know than to know something that was wrong.

By the way, a Bulgarian I met lately in Moscow," Ivan went on, seeming not to hear his brother's words, "told me about the crimes committed by Turks and Circassians in all parts of Bulgaria through fear of a general rising of the Slavs. They burn villages, murder, outrage women and children, they nail their prisoners by the ears to the fences, leave them so till morning, and in the morning they hang them- all sorts of things you can't imagine. People talk sometimes of bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel. The tiger only tears and gnaws, that's all he can do. He would never think of nailing people by the ears, even if he were able to do it.These Turks took a pleasure in torturing children, -too; cutting the unborn child from the mothers womb, and tossing babies up in the air and catching them on the points of their bayonets before their mothers' eyes. Doing it before the mothers' eyes was what gave zest to the amusement. Here is another scene that I thought very interesting. Imagine a trembling mother with her baby in her arms, a circle of invading Turks around her. They've planned a diversion: they pet the baby, laugh to make it laugh. They succeed, the baby laughs. At that moment a Turk points a pistol four inches from the baby's face. The baby laughs with glee, holds out its little hands to the pistol, and he pulls the trigger in the baby's face and blows out its brains. Artistic, wasn't it? By the way, Turks are particularly fond of sweet things, they say.

The Hartle-Hawking derivation of the unconditional probability of the existence of a universe of our sort is inconsistent with classical theism. The unconditional probability is very high, near to 1. For purposes of simplification, we are saying the probability is 99 percent; there is a 99 percent probability that a universe of our sort—I will call it a Hartle-Hawking universe—exists uncaused.The universe exists uncaused since the probability amplitude is determined by a summation or path integral over all possible histories of a finite universe. That is, the probability that a Hartle-Hawking universe exists follows directly from the natural-mathematical properties of possible finite universes; there is no need for a cause, probabilistic or otherwise, for there to be a 99 percent probability that a Hartle-Hawking universe will exist.This is not consistent with classical theism. According to classical theism, if a universe is to have any probability of existing, this probability is dependent on God's dispositions, beliefs, or choices. But the Hartle-Hawking probability is not dependent on any supernatural states or acts; Hartle and Hawking do not sum over anything supernatural in their path integral derivation of the probability amplitude.Furthermore, according to classical theism, the probability that a universe exist without divine causation is 0, and the probability that if a universe exists, it is divinely caused, is 1. Thus, the probabilities that are implied by classical theism are inconsistent with the probabilities implied by the Hartle-Hawking wave function of the universe.

I regard anti-Semitism as ineradicable and as one element of the toxin with which religion has infected us. Perhaps partly for this reason, I have never been able to see Zionism as a cure for it. American and British and French Jews have told me with perfect sincerity that they are always prepared for the day when 'it happens again' and the Jew-baiters take over. (And I don't pretend not to know what they are talking about: I have actually seen the rabid phenomenon at work in modern and sunny Argentina and am unable to forget it.) So then, they seem to think, they will take refuge in the Law of Return, and in Haifa, or for all I know in Hebron. Never mind for now that if all of world Jewry did settle in Palestine, this would actually necessitate further Israeli expansion, expulsion, and colonization, and that their departure under these apocalyptic conditions would leave the new brownshirts and blackshirts in possession of the French and British and American nuclear arsenals. This is ghetto thinking, hardly even fractionally updated to take into account what has changed. The important but delayed realization will have to come: Israeli Jews are a part of the diaspora, not a group that has escaped from it. Why else does Israel daily beseech the often-flourishing Jews of other lands, urging them to help the most endangered Jews of all: the ones who rule Palestine by force of arms? Why else, having supposedly escaped from the need to rely on Gentile goodwill, has Israel come to depend more and more upon it? On this reckoning, Zionism must constitute one of the greatest potential non sequiturs in human history.

There may be some truth (atheists) do not need to believe in a god to be good, but then if they do not believe in a god, who do they believe gives the Universal Law of following good and shunning evil? Obviously, mankind. But then that is a dangerous thing, for if a man does not believe in a god capable of giving perfect laws, he is in the position of declaring all laws come from man, and as man is imperfect, he can declare that as fallible men make imperfect laws, he can pick and choose what he wishes to follow, that which, in his own mind seems good. He does not believe in divine retribution, therefore he can also declare his own morality contrary to what the divine may decree simply because he believes there is no divine decree. He may follow his every whim and passion, declaring it to be good when it may be very evil, for he like all men is imperfect, so how can he tell what is verily good? The atheist is in danger of mistaking vice for good and consequently follow another slave master and tyrant, his own physical and mental weakness. Evil would be wittingly or unwittingly perpetrated, therefore, to recognise the existence of a perfect divine being that gives perfect Universal Laws is much better than not to believe in a god, for if there is a perfect god, they will not allow their laws to be broken with impunity as in the case with many corrupt judges on earth, but will punish accordingly in due time. Therefore, to be pious and reverent is the surest path to true freedom as a perfect god will give perfect laws to prevent all manner of slavery, tyranny and moral wantonness, even if we do not understand why they are good laws at times.

One of the questions asked by al-Balkhi, and often repeated to this day, is this: Why do the children of Israel continue to suffer? My grandmother Dodo thought it was because the goyim were jealous. The seder for Passover (which is a shame-faced simulacrum of a Hellenic question-and-answer session, even including the wine) tells the children that it's one of those things that happens to every Jewish generation. After the Shoah or Endlösung or Holocaust, many rabbis tried to tell the survivors that the immolation had been a punishment for 'exile,' or for insufficient attention to the Covenant. This explanation was something of a flop with those whose parents or children had been the raw material for the 'proof,' so for a time the professional interpreters of god's will went decently quiet. This interval of ambivalence lasted until the war of 1967, when it was announced that the divine purpose could be discerned after all. How wrong, how foolish, to have announced its discovery prematurely! The exile and the Shoah could now both be understood, as part of a heavenly if somewhat roundabout scheme to recover the Western Wall in Jerusalem and other pieces of biblically mandated real estate.I regard it as a matter of self-respect to spit in public on rationalizations of this kind. (They are almost as repellent, in their combination of arrogance, masochism, and affected false modesty, as Edith Stein's 'offer' of her life to expiate the regrettable unbelief in Jesus of her former fellow Jews.) The sage Jews are those who have put religion behind them and become in so many societies the leaven of the secular and the atheist.

A miracle is a violation of the laws of nature; and because firm and unalterable experience has established these laws, the case against a miracle is—just because it is a miracle—as complete as any argument from experience can possibly be imagined to be. Why is it more than merely probable that all men must die, that lead cannot when not supported remain suspended in the air, that fire consumes wood and is extinguished by water, unless it is that these events are found agreeable to the laws of nature, and for things to go differently there would have to be a violation of those laws, or in other words a miracle? Nothing is counted as amiracle if it ever happens in the common course of nature. When a man who seems to be in good health suddenly dies, this isn't a miracle; because such a kind of death, though more unusual than any other, has yet often been observedto happen. But a dead man’s coming to life would be a miracle, because that has never been observed in any age or country. So there must be a uniform experience against every miraculous event, because otherwise the event wouldn't count as a ‘miracle’. And as a uniform experience amounts to a proof, we have here a direct and full proof against the existence of any miracle, just because it’s a miracle; andsuch a proof can’t be destroyed or the miracle made credible except by an opposite proof that is even stronger.This clearly leads us to a general maxim that deserves ofour attention:No testimony is sufficient to establish a miracle unless it is of such a kind that its falsehood would be more miraculous than the fact that it tries to establish. And even in that case there is a mutual destruction ofarguments, and the stronger one only gives us an assurance suitable to the force that remains to it after the force needed to cancel the other has beensubtracted.

About once or twice every month I engage in public debates with those whose pressing need it is to woo and to win the approval of supernatural beings. Very often, when I give my view that there is no supernatural dimension, and certainly not one that is only or especially available to the faithful, and that the natural world is wonderful enough—and even miraculous enough if you insist—I attract pitying looks and anxious questions. How, in that case, I am asked, do I find meaning and purpose in life? How does a mere and gross materialist, with no expectation of a life to come, decide what, if anything, is worth caring about?Depending on my mood, I sometimes but not always refrain from pointing out what a breathtakingly insulting and patronizing question this is. (It is on a par with the equally subtle inquiry: Since you don't believe in our god, what stops you from stealing and lying and raping and killing to your heart's content?) Just as the answer to the latter question is: self-respect and the desire for the respect of others—while in the meantime it is precisely those who think they have divine permission who are truly capable of any atrocity—so the answer to the first question falls into two parts. A life that partakes even a little of friendship, love, irony, humor, parenthood, literature, and music, and the chance to take part in battles for the liberation of others cannot be called 'meaningless' except if the person living it is also an existentialist and elects to call it so. It could be that all existence is a pointless joke, but it is not in fact possible to live one's everyday life as if this were so. Whereas if one sought to define meaninglessness and futility, the idea that a human life should be expended in the guilty, fearful, self-obsessed propitiation of supernatural nonentities… but there, there. Enough.

You frequently state, and in your letter you imply, that I have developed a completely one-sided outlook and look at everything in terms of science. Obviously my method of thought and reasoning is influenced by a scientific training – if that were not so my scientific training will have been a waste and a failure. But you look at science (or at least talk of it) as some sort of demoralizing invention of man, something apart from real life, and which must be cautiously guarded and kept separate from everyday existence. But science and everyday life cannot and should not be separated. Science, for me, gives a partial explanation of life. In so far as it goes, it is based on fact, experience and experiment. Your theories are those which you and many other people find easiest and pleasantest to believe, but so far as I can see, they have no foundation other than they leaf to a pleasanter view of life (and an exaggerated idea of our own importance)...I agree that faith is essential to success in life (success of any sort) but I do not accept your definition of faith, i.e. belief in life after death. In my view, all that is necessary for faith is the belief that by doing our best we shall come nearer to success and that success in our aims (the improvement of the lot of mankind, present and future) is worth attaining. Anyone able to believe in all that religion implies obviously must have such faith, but I maintain that faith in this world is perfectly possible without faith in another world…It has just occurred to me that you may raise the question of the creator. A creator of what? ... I see no reason to believe that a creator of protoplasm or primeval matter, if such there be, has any reason to be interested in our significant race in a tiny corner of the universe, and still less in us, as still more significant individuals. Again, I see no reason why the belief that we are insignificant or fortuitous should lessen our faith – as I have defined it.
