One attempt to avoid the problem of induction involves weakening the demand that scientific knowledge be proven true, and resting content with the claim that scientific claims can be shown to be probably true in the light of the evidence. So the vast number of observations that can be invoked to support the claim that materials denser than air fall diWInwards on earth, although it does not permit us to prove the truth of the claim, does warrant the assertion that the claim is probably true.

In science's pecking order, evolutionary biology lurks somewhere near the bottom, far closer to phrenology than to physics. For evolutionary biology is a historical science, laden with history's inevitable imponderables. We evolutionary biologists cannot generate a Cretaceous Park to observe exactly what killed the dinosaurs; and, unlike "harder" scientists, we usually cannot resolve issues with a simple experiment, such as adding tube A to tube B and noting the color of the mixture.

How can we find spiritual meaning in a scientific worldview? Spirituality is a way of being in the world, a sense of one’s place in the cosmos, a relationship to that which extends beyond oneself. . . . Does scientific explanation of the world diminish its spiritual beauty? I think not. Science and spirituality are complementary, not conflicting; additive, not detractive. Anything that generates a sense of awe may be a source of spirituality. Science does this in spades. (158-159)

But when we reduce sex to a function, we also invoke the idea of dysfunction. We are no longer talking about the art of sex; rather, we are talking about the mechanics of sex. Science has replaced religion as the authority; and science is a more formidable arbiter. Medicine knows how to scare even those who scoff at religion. Compared with a diagnosis, what's a mere sin? We used to moralize; today we normalize, and performance anxiety is the secular version of our old religious guilt.

Of the many 'firsts' with which I have been involved at the Texas Heart Institute —including the first successful human heart transplant in the United States and the first total artificial heart transplant in the world—the achievement that may have the greatest impact on health care did not occur in the operating room or in the research laboratory. It happened on a piece of paper... when we created the first-ever packaged pricing plan for cardiovascular surgical procedures.

Çoğumuz sevilmeyi ummuşuzdur yalnızca giydirilip beslenmeyi değil, anlaşılmayı, dikkate alınmayı, saygı gösterilmeyi beklemişizdir. Çoğumuz inanabilmeyi ummuşuzdur. Küçükken, o insan buluşu olan yalanı henüz bilmiyorduk yalnızca sözlerle söylenen yalanı değil, sesle, mimiklerle, gözlerle, yüzsel anlatımla yalan söylemeyi de bilmiyorduk.

So my antagonist said, "Is it impossible that there are flying saucers? Can you prove that it's impossible?" "No", I said, "I can't prove it's impossible. It's just very unlikely". At that he said, "You are very unscientific. If you can't prove it impossible then how can you say that it's unlikely?" But that is the way that is scientific. It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

Is the conclusion that the universe was designed - and that the design extends deeply into life - science, philosophy, religion, or what? In a sense it hardly matters. By far the most important question is not what category we place it in, but whether a conclusion is true. A true philosophical or religious conclusion is no less true than a true scientific one. Although universities might divide their faculty and courses into academic categories, reality is not obliged to respect such boundaries.

In the deeps are the violence and terror of which psychology has warned us. But if you ride these monsters deeper down, if you drop with them farther over the world's rim, you find what our sciences cannot locate or name, the substrate, the ocean or matrix or ether which buoys the rest, which gives goodness its power for good, and evil its power for evil, the unified field: our complex and inexplicable caring for each other, and for our life together here. This is given. It is not learned.

The business of scepticism is to be dangerous. Scepticism challenges established institutions. If we teach everybody, including, say, high school students, habits of sceptical thought, they will probably not restrict their scepticism to UFOs, aspirin commercials and 35,000-year-old channellees. Maybe they’ll start asking awkward questions about economic, or social, or political, or religious institutions. Perhaps they’ll challenge the opinions of those in power. Then where would we be?

I have not yet lost a feeling of wonder, and of delight, that this delicate motion should reside in all the things around us, revealing itself only to him who looks for it. I remember, in the winter of our first experiments, just seven years ago, looking on snow with new eyes. There the snow lay around my doorstep — great heaps of protons quietly precessing in the earth's magnetic field. To see the world for a moment as something rich and strange is the private reward of many a discovery.

No one can say if you are that person who, given good paint, good brushes, and a fine canvas, can produce something better than the factory man. That is, and has always been, beyond the realm of science. You do have the attitude of the dreamer about you. For that reason, I haven't the heart to argue anymore about this - it is a hopeless talk. And for a simple factory man like me, an effort must be abandoned once its hopelessness is exposed. Only the artist perseveres in such circumstances.

In college, in the early 1950s, I began to learn a little about how science works, the secrets of its great success, how rigorous the standards of evidence must be if we are really to know something is true, how many false starts and dead ends have plagued human thinking, how our biases can colour our interpretation of evidence, and how often belief systems widely held and supported by the political, religious and academic hierarchies turn out to be not just slightly in error, but grotesquely wrong.

The definitive study of the herd instincts of astronomers has yet to be written, Fernie said, but there are times when we resemble nothing so much as a herd of antelope, heads down in tight formation, thundering with firm determination in a particular direction across the plain. At a given signal from the leader we whirl about, and, with equally firm determination, thunder off in quite a different direction, still in tight parallel formation.(quoting an observation made by astronomer J. Donal Fernie)

It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.[Recalling in 1936 the discovery of the nucleus in 1909, when some alpha particles were observed instead of travelling through a very thin gold foil were seen to rebound backward, as if striking something much more massive than the particles themselves. He won the Nobel Prize in Chemistry for this discovery.]
