God Is Not Great

to the Galapagos Islands, lived in the arduous conditions of the tiny island of Daphne Major, and actually watched and measured the way that finches evolved and adapted as their surroundings changed. They have shown conclusively that the size and shape of the finches’ beaks would adjust themselves to drought and scarcity, by adaption to the size and character of different seeds and beetles. Not only could the three-million-year-old original flock change in one way, but if the beetle and seed situation changed back, their beaks could follow suit. The Grants took care, and they saw it happening, and could publish their findings and proofs for all to see. We are in their debt. Their lives were harsh, but who could wish that they had mortified themselves in a holy cave or on top of a sacred pillar instead?

In 2005, a team of researchers at the University of Chicago conducted serious work on two genes, known as microcephalin and ASPM, that when disabled are the cause of microcephaly. Babies born with this condition have a shrunken cerebral cortex, quite probably an occasional reminder of the period when the human brain was very much smaller than it is now. The evolution of humans has been generally thought to have completed itself about fifty to sixty thousand years ago (an instant in evolutionary time), yet those two genes have apparently been evolving faster in the past thirty-seven thousand years, raising the possibility that the human brain is a work in progress. In March 2006, further work at the same university revealed that there are some seven hundred regions of the human genome where genes have been reshaped by natural selection within the past five thousand to fifteen thousand years. These genes include some of those responsible for our “senses of taste and smell, digestion, bone structure, skin color and brain function.” (One of the great emancipating results of genomics is to show that all “racial” and color differences are recent, superficial, and misleading.) It is a moral certainty that between the time I finish writing this book and the time that it is published, several more fascinating and enlightening discoveries will be made in this burgeoning field. It may be too soon to say that all the progress is positive or “upward,” but human development is still under way. It shows in the manner in which we acquire immunities, and also in the way in which we do not. Genome studies have identified early groups of northern Europeans who learned to domesticate cattle and acquired a distinct gene for “lactose tolerance,” while some people of more recent African descent (we all originate from Africa) are prone to a form of sickle-cell anemia which, while upsetting in and of itself, results from an earlier mutation that gave protection against malaria. And all this will be further clarified if we are modest and patient enough to understand the building blocks of nature and the lowly stamp of our origins. No divine plan, let alone angelic intervention, is required. Everything works without that assumption.

Thus, though I dislike to differ with such a great man, Voltaire was simply ludicrous when he said that if god did not exist it would be necessary to invent him. The human invention of god is the problem to begin with. Our evolution has been examined “backward,” with life temporarily outpacing extinction, and knowledge now at last capable of reviewing and explaining ignorance. Religion, it is true, still possesses the huge if cumbersome and unwieldy advantage of having come “first.” But as Sam Harris states rather pointedly in The End of Faith, if we lost all our hard-won knowledge and all our archives, and all our ethics and morals, in some Marquez-like fit of collective amnesia, and had to reconstruct everything essential from scratch, it is difficult to imagine at what point we would need to remind or reassure ourselves that Jesus was born of a virgin.

Thoughtful believers can take some consolation, too. Skepticism and discovery have freed them from the burden of having to defend their god as a footling, clumsy, straws-in-the-hair mad scientist, and also from having to answer distressing questions about who inflicted the syphilis bacillus or mandated the leper or the idiot child, or devised the torments of Job. The faithful stand acquitted on that charge: we no longer have any need of a god to explain what is no longer mysterious. What believers will do, now that their faith is optional and private and irrelevant, is a matter for them. We should not care, as long as they make no further attempt to inculcate religion by any form of coercion.

CHAPTER SEVEN Revelation: The Nightmare of the “Old” Testament

Another way in which religion betrays itself, and attempts to escape mere reliance on faith and instead offer “evidence” in the sense normally understood, is by the argument from revelation. On certain very special occasions, it is asserted, the divine will was made known by direct contact with randomly selected human beings, who were supposedly vouchsafed unalterable laws that could then be passed on to those less favored.

There are some very obvious objections to be made to this. In the first place, several such disclosures have been claimed to occur, at different times and places, to hugely discrepant prophets or mediums. In some cases— most notably the Christian—one revelation is apparently not sufficient, and needs to be reinforced by successive apparitions, with the promise of a further but ultimate one to come. In other cases, the opposite difficulty occurs and the divine instruction is delivered, only once, and for the final time, to an obscure personage whose lightest word then becomes law. Since all of these revelations, many of them hopelessly inconsistent, cannot by definition be simultaneously true, it must follow that some of them are false and illusory. It could also follow that only one of them is authentic, but in the first place this seems dubious and in the second place it appears to necessitate religious war in order to decide whose revelation is the true one. A further difficulty is the apparent tendency of the Almighty to reveal himself only to unlettered and quasi-historical individuals, in regions of Middle Eastern wasteland that were long the home of idol worship and superstition, and in many instances already littered with existing prophecies.

The syncretic tendencies of monotheism, and the common ancestry of the tales, mean in effect that a rebuttal to one is a rebuttal to all. Horribly and hatefully though they may have fought with one another, the three monotheisms claim to share a descent at least from the Pentateuch of Moses, and the Koran certifies Jews as “people of the book,” Jesus as a prophet, and a virgin as his mother. (Interestingly, the Koran does not blame the Jews for the murder of Jesus, as one book of the Christian New Testament does, but this is only because it makes the bizarre claim that someone else was crucified by the Jews in his place.)

The foundation story of all three faiths concerns the purported meeting between Moses and god, at the summit of Mount Sinai. This in turn led to the handing down of the Decalogue, or Ten Commandments. The tale is told in the second book of Moses, known as the book of Exodus, in chapters 20–40. Most attention has been concentrated on chapter 20 itself, where the actual commandments are given. It should not perhaps be necessary to summarize and expose these, but the effort is actually worthwhile.

In the first place (I am using the King James or “Authorized” Version: one among many rival texts laboriously translated by mortals either from Hebrew or Greek or Latin), the so-called commandments do not appear as a neat list of ten orders and prohibitions. The first three are all variations of the same one, in which god insists on his own primacy and exclusivity, forbids the making of graven images, and prohibits the taking of his own name in vain. This prolonged throat-clearing is accompanied by some very serious admonitions, including a dire warning that the sins of the fathers will be visited on their children “even unto the third and fourth generation.” This negates the moral and reasonable idea that children are innocent of their parents’ offenses. The fourth commandment insists on the observance of a holy Sabbath day, and forbids all believers—and their slaves and domestic servants—to perform any work in the course of it. It is added that, as was said in the book of Genesis, god made all the world in six days and rested on the seventh (leaving room for speculation as to what he did on the eighth day). The dictation then becomes more terse. “Honor thy father and thy mother” (this not for its own sake but in order “that thy days may be long upon the land which the Lord thy God giveth thee”). Only then come the four famous “shalt nots,” which flatly prohibit killing, adultery, theft, and false witness. Finally, there is a ban on covetousness, forbidding the desire for “thy neighbor’s” house, manservant, maidservant, ox, ass, wife, and other chattel.

It would be harder to find an easier proof that religion is man-made. There is, first, the monarchical growling about respect and fear, accompanied by a stern reminder of omnipotence and limitless revenge, of the sort with which a Babylonian or Assyrian emperor might have ordered the scribes to begin a proclamation. There is then a sharp reminder to keep working and only to relax when the absolutist says so. A few crisp legalistic reminders follow, one of which is commonly misrendered because the original Hebrew actually says “thou shalt do no murder.” But however little one thinks of the Jewish tradition, it is surely insulting to the people of Moses to imagine that they had come this far under the impression that murder, adultery, theft, and perjury were permissible. (The same unanswerable point can be made in a different way about the alleged later preachings of Jesus: when he tells the
