Galileo reborn 伽利略的复生

In his own lifetime Galileo was the centre of violent controversy; but the scientific dust has long since settled, and today we can see even his famous clash with the Inquisition in something like its proper perspective. But, in contrast, it is only in modern times that Galileo has become a problem child for historians of science.
The old view of Galileo was delightfully uncomplicated. He was, above all, a man who experimented: who despised the prejudices and book learning of the Aristotelians, who put his questions to nature instead of to the ancients, and who drew his conclusions fearlessly. He had been the first to turn a telescope to the sky, and he had seen there evidence enough to overthrow Aristotle and Ptolemy together. He was the man who climbed the Leaning Tower of Pisa and dropped various weights from the top, who rolled balls down inclined planes, and then generalized the results of his many experiments into the famous law of free fall.
But a closer study of the evidence, supported by a deeper sense of the period, and particularly by a new consciousness of the philosophical undercurrents in the scientific revolution, has profoundly modified this view of Galileo. Today, although the old Galileo lives on in many popular writings, among historians of science a new and more sophisticated picture has emerged. At the same time our sympathy fro Galileo's opponents has grown somewhat. His telescopic observations are justly immortal; they aroused great interest at the time, they had important theoretical consequences, and they provided a striking demonstration of the potentialities hidden in instruments and apparatus. But can we blame those who looked and failed to see what Galileo saw, if we remember that to use a telescope at the limit of its powers calls for long experience and intimate familiarity with one's instrument? Was the philosopher who refused to look through Galileo's telescope more culpable than those who alleged that the spiral nebulae observed with Lord Rosse's great telescope in the eighteen-forties were scratches left by the grinder? We can perhaps forgive those who said the moons of Jupiter were produced by Galileo's spyglass if we recall that in his day, as for centuries before, curved glass was the popular contrivance for producing not truth but illusion, untruth; and if a single curved glass would distort nature, how much more would a pair of them?

伽利略在世时是激烈论战的中心。但是，自他逝世以来，那场科学上的纷争早已平息了下来，甚至他和宗教法庭的著名冲突，我们今天也能正确如实地看待。但是相比之下，对于科学史家来说，伽利略只是在现代才变成了一个新的难题。
令人高兴的是，过去对伽利略的看法并不复杂。他首先是个实验工作者，他蔑视亚里士多德学派的偏见和空洞的书本知识。他向自然界而不是向古人提出问题，并大胆地得出结论。他是第一个把望远镜对准天空的人，观察到的论据足以把亚里士多德和托勒密一起推翻。他就是那个曾经爬上比萨斜塔，从塔顶向下抛掷积各种重物的人；他是那个使地球体沿斜面向下滚动，然后将多次实验结果概括成著名的自由落体定律的人。
但是，对那个时代的深化了解，尤其是以科学家革命中哲学潜流的新意识为依据，进一步仔细研究，就会极大地改变对伽利略的看法。今天，虽然已故的伽利略继续活在许多通俗读物中，但在科学史家中间，一个新的更加复杂的伽利略形象出现了。与此同时，我们对伽利略的反对派的同情也有所增加。伽利略用望远镜所作的观察确实是不朽的，这些观察当时引起人们极大的兴趣，具有重要的理论意义，并充分显示出了仪表和仪器的潜在力量。
