Cope laughed. “I wouldn’t worry yourself, my friend. Eobasileus has been extinct for thirty-seven million years.”At this, the preacher could no longer contain himself. “Nonsense! Utter nonsense!”“Nonsense?” asked Cope.“The archbishop James Ussher, using the Holy Bible itself, worked back generation by generation, mathematically, and calculated that the Earth was created on Sunday, October 23, 4004 BC at precisely eight a.m.”“Did he, now? Eight a.m., precisely?”“Precisely,” the preacher insisted.Copy and Sternberg exchanged amused looks.“Well,” Cope replied, “since the rotation of the Earth assures us that it’s always eight a.m. somewhere in the world, I suppose I should applaud him for guessing the correct time, at least.” The cowboy couldn’t help but interject.“Pardon me, Preacher, but if I recall correctly, didn’t the Bible say something about the Lord resting on the seventh day?”The preacher looked confused. “What?”“I’m certain of it.” The cowboy quickly snatched the Bible from the preacher’s hands and opened it to the first page of Genesis. “Sure. Here it is. He got started on a Monday, making light and darkness. By the time he got around to creating the Earth it was well into the third day. I make that to be Wednesday, not Sunday.”Nonplussed and blushing, the preacher snatched his Bible back. The cowboy shrugged. “Looks to me like your archbishop pulled a fast one, Preacher. Or maybe he just wasn’t all that good at calculating.
Tell me something. Do you believe in God?'Snow darted an apprehensive glance in my direction. 'What? Who still believes nowadays?''It isn't that simple. I don't mean the traditional God of Earth religion. I'm no expert in the history of religions, and perhaps this is nothing new--do you happen to know if there was ever a belief in an...imperfect God?''What do you mean by imperfect?' Snow frowned. 'In a way all the gods of the old religions were imperfect, considered that their attributes were amplified human ones. The God of the Old Testament, for instance, required humble submission and sacrifices, and and was jealous of other gods. The Greek gods had fits of sulks and family quarrels, and they were just as imperfect as mortals...''No,' I interrupted. 'I'm not thinking of a god whose imperfection arises out of the candor of his human creators, but one whose imperfection represents his essential characteristic: a god limited in his omniscience and power, fallible, incapable of foreseeing the consequences of his acts, and creating things that lead to horror. He is a...sick god, whose ambitions exceed his powers and who does not realize it at first. A god who has created clocks, but not the time they measure. He has created systems or mechanisms that serves specific ends but have now overstepped and betrayed them. And he has created eternity, which was to have measured his power, and which measures his unending defeat.'Snow hesitated, but his attitude no longer showed any of the wary reserve of recent weeks:'There was Manicheanism...''Nothing at all to do with the principles of Good and Evil,' I broke in immediately. 'This god has no existence outside of matter. He would like to free himself from matter, but he cannot...'Snow pondered for a while:'I don't know of any religion that answers your description. That kind of religion has never been...necessary. If i understand you, and I'm afraid I do, what you have in mind is an evolving god, who develops in the course of time, grows, and keeps increasing in power while remaining aware of his powerlessness. For your god, the divine condition is a situation without a goal. And understanding that, he despairs. But isn't this despairing god of yours mankind, Kelvin? Is it man you are talking about, and that is a fallacy, not just philosophically but also mystically speaking.'I kept on:'No, it's nothing to do with man. man may correspond to my provisional definition from some point of view, but that is because the definition has a lot of gaps. Man does not create gods, in spite of appearances. The times, the age, impose them on him. Man can serve is age or rebel against it, but the target of his cooperation or rebellion comes to him from outside. If there was only a since human being in existence, he would apparently be able to attempt the experiment of creating his own goals in complete freedom--apparently, because a man not brought up among other human beings cannot become a man. And the being--the being I have in mind--cannot exist in the plural, you see? ...Perhaps he has already been born somewhere, in some corner of the galaxy, and soon he will have some childish enthusiasm that will set him putting out one star and lighting another. We will notice him after a while...''We already have,' Snow said sarcastically. 'Novas and supernovas. According to you they are candles on his altar.''If you're going to take what I say literally...'...Snow asked abruptly:'What gave you this idea of an imperfect god?''I don't know. It seems quite feasible to me. That is the only god I could imagine believing in, a god whose passion is not a redemption, who saves nothing, fulfills no purpose--a god who simply is.
Darwin singled out the eye as posing a particularly challenging problem: 'To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree.' Creationists gleefully quote this sentence again and again. Needless to say, they never quote what follows. Darwin's fulsomely free confession turned out to be a rhetorical device. He was drawing his opponents towards him so that his punch, when it came, struck the harder. The punch, of course, was Darwin's effortless explanation of exactly how the eye evolved by gradual degrees. Darwin may not have used the phrase 'irreducible complexity', or 'the smooth gradient up Mount Improbable', but he clearly understood the principle of both. 'What is the use of half an eye?' and 'What is the use of half a wing?' are both instances of the argument from 'irreducible complexity'. A functioning unit is said to be irreducibly complex if the removal of one of its parts causes the whole to cease functioning. This has been assumed to be self-evident for both eyes and wings. But as soon as we give these assumptions a moment's thought, we immediately see the fallacy. A cataract patient with the lens of her eye surgically removed can't see clear images without glasses, but can see enough not to bump into a tree or fall over a cliff. Half a wing is indeed not as good as a whole wing, but it is certainly better than no wing at all. Half a wing could save your life by easing your fall from a tree of a certain height. And 51 per cent of a wing could save you if you fall from a slightly taller tree. Whatever fraction of a wing you have, there is a fall from which it will save your life where a slightly smaller winglet would not. The thought experiment of trees of different height, from which one might fall, is just one way to see, in theory, that there must be a smooth gradient of advantage all the way from 1 per cent of a wing to 100 per cent. The forests are replete with gliding or parachuting animals illustrating, in practice, every step of the way up that particular slope of Mount Improbable. By analogy with the trees of different height, it is easy to imagine situations in which half an eye would save the life of an animal where 49 per cent of an eye would not. Smooth gradients are provided by variations in lighting conditions, variations in the distance at which you catch sight of your prey—or your predators. And, as with wings and flight surfaces, plausible intermediates are not only easy to imagine: they are abundant all around the animal kingdom. A flatworm has an eye that, by any sensible measure, is less than half a human eye. Nautilus (and perhaps its extinct ammonite cousins who dominated Paleozoic and Mesozoic seas) has an eye that is intermediate in quality between flatworm and human. Unlike the flatworm eye, which can detect light and shade but see no image, the Nautilus 'pinhole camera' eye makes a real image; but it is a blurred and dim image compared to ours. It would be spurious precision to put numbers on the improvement, but nobody could sanely deny that these invertebrate eyes, and many others, are all better than no eye at all, and all lie on a continuous and shallow slope up Mount Improbable, with our eyes near a peak—not the highest peak but a high one.
