.And so the image of the mad scientist haunts our world - down to the white-coated loonies of Saturday morning children’s TV and the plethora of Faustian bargains in popular culture, from the eponymous Dr Faustus himself to Dr Frankenstein, Dr Strangelove, and Jurassic Park.But we can’t simply conclude that science puts too much power into the hands of morally feeble technologists or corrupt, power-crazed politicians and so decide to get rid of it.Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.* Advances in transportation, communication and entertainment have transformed and unified the world.In opinion poll after opinion poll science is rated among the most admired and trusted occupations, despite the misgivings.The sword of science is double-edged.Its awesome power forces on all of us, including politicians, a new responsibility - more attention to the long-term consequences of technology, a global and transgenerational perspective, an incentive to avoid easy appeals to nationalism and chauvinism.Mistakes are becoming too expensive.[* At a large dinner party recently, I asked the assembled guests - ranging in age, I guess, from thirties to sixties - how many of them would be alive today if not for antibiotics, cardiac pacemakers, and the rest of the panoply of modern medicine.Only one hand went up.It was not mine.]Do we care what’s true? Does it matter?…where ignorance is bliss,Tis folly to be wisewrote the poet Thomas Gray.But is it? Edmund Way Teale in his 1950 book Circle of the Seasons understood the dilemma better:It is morally as bad not to care whether a thing is true or not, so long as it makes you feel good, as it is not to care how you got your money as long as you have got it.It’s disheartening to discover government corruption and incompetence, for example; but it is better not to know about it? Whose interest does ignorance serve? If we humans bear, say, hereditary propensities toward the hatred of strangers, isn’t self-knowledge the only antidote? If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?In The Genealogy of Morals, Friedrich Nietzsche, as so many before and after, decries the ‘unbroken progress in the self-belittling of man’ brought about by the scientific revolution.Nietzsche mourns the loss of ‘man’s belief in his dignity, his uniqueness, his irreplaceability in the scheme of existence’.For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.Which attitude is better geared for our long-term survival? Which gives us more leverage on our future? And if our naive self-confidence is a little undermined in the process, is that altogether such a loss? Is there not cause to welcome it as a maturing and character-building experience?To discover that the Universe is some 8 to 15 billion and not 6 to 12 thousand years old* improves our appreciation of its sweep and grandeur; to entertain the notion that we are a particularly complex arrangement of atoms, and not some breath of divinity, at the very least enhances our respect for atoms; to discover, as now seems probable, that our planet is one of billions of other worlds in the Milky Way galaxy and that our galaxy is one of billions more, majestically expands the arena of what is possible; to find that our ancestors were also the ancestors of apes ties us to the rest of life and makes possible important - if occasionally rueful - reflections on human nature.[* ‘No thinking religious person believes this.Old hat,’ writes one of the referees of this book.But many ‘scientific creationists’ not only believe it, but are making increasingly aggressive and successful efforts to have it taught in the schools, museums, zoos, and textbooks.Why? Because adding up the ‘begats’, the ages of patriarchs and others in the Bible gives such a figure, and the Bible is ‘inerrant’.]Plainly there is no way back.Like it or not, we are stuck with science.We had better make the best of it.When we finally come to terms with it and fully recognize its beauty and its power, we will find, in spiritual as well as in practical matters, that we have made a bargain strongly in our favour.But superstition and pseudoscience keep getting in the way, distracting all the ‘Buckleys’ among us, providing easy answers, dodging sceptical scrutiny, casually pressing our awe buttons and cheapening the experience, making us routine and comfortable practitioners as well as victims of credulity.Yes, the world would be a more interesting place if there were UFOs lurking in the deep waters off Bermuda and eating ships and planes, or if dead people could take control of our hands and write us messages.It would be fascinating if adolescents were able to make telephone handsets rocket off their cradles just by thinking at them, or if our dreams could, more often than can be explained by chance and our knowledge of the world, accurately foretell the future.These are all instances of pseudoscience.They purport to use the methods and findings of science, while in fact they are faithless to its nature – often because they are based on insufficient evidence or because they ignore clues that point the other way.They ripple with gullibility.With the uninformed cooperation (and often the cynical connivance) of newspapers, magazines, book publishers, radio, television, movie producers and the like, such ideas are easily and widely available.Far more difficult to come upon, as I was reminded by my encounter with Mr ‘Buckley’, are the alternative, more challenging and even more dazzling findings of science.Pseudoscience is easier to contrive than science, because distracting confrontations with reality – where we cannot control the outcome of the comparison – are more readily avoided.The standards of argument, what passes for evidence, are much more relaxed.In part for these same reasons, it is much easier to present pseudoscience to the general public than science.But this isn’t enough to explain its popularity.Naturally people try various belief systems on for size, to see if they help.And if we’re desperate enough, we become all too willing to abandon what may be perceived as the heavy burden of scepticism.Pseudoscience speaks to powerful emotional needs that science often leaves unfulfilled.It caters to fantasies about personal powers we lack and long for (like those attributed to comic book superheroes today, and earlier, to the gods).In some of its manifestations, it offers satisfaction of spiritual hungers, cures for disease, promises that death is not the end.It reassures us of our cosmic centrality and importance.It vouchsafes that we are hooked up with, tied to, the Universe.* Sometimes it’s a kind of halfway house between old religion and new science, mistrusted by both.[* Although it’s hard for me to see a more profound cosmic connection than the astonishing findings of modern nuclear astrophysics: except for hydrogen, all the atoms that make each of us up – the iron in our blood, the calcium in our bones, the carbon in our brains – were manufactured in red giant stars thousands of light years away in space and billions of years ago in time.We are, as I like to say, starstuff [ Pobierz całość w formacie PDF ]
