Yeah, well. Fortean Times.:rolleyes:
Bruno was an extremist hermetic*, and a heretic* by anyone’s standards, scarcely a Christian at all. He had zero understanding of astronomy, and pretty clearly only liked the Copernican theory because it was so weird and far out.
[*Note: these are different words.]
But although the churches (both Catholic and Protestant) did not like it very much, lots of intellectuals at the time were influenced by hermeticism, including Copernicus, Kepler and Newton (and many who were more interested in magical spells than anything we would call science). With a handful of exceptions, the vast majority of them were much more moderate than Bruno, and (again, including Copernicus, Kepler and Newton) did not get in any real trouble for their hermetic leanings. Some of them, like Copernicus, were well respected Church officials.
Galileo, on the other hand, was totally opposed to the hermetic outlook, and in everything but his heliocentrism always remained a theologically orthodox Catholic. That is why he never accepted Kepler’s laws of planetary motion (despite the fact that they fit the observed data way better than anything Galileo could come up with), or Kepler’s theory that the ocean tides are caused by a force emanating from the moon: it all smelled too much of mystical hermeticism to proudly rational Galileo. The Church authorities knew this. Galileo had been a prominent celebrity for decades by the time of his trial, and you can be sure the inquisition had checked him out throughly (and found him to be clean) years before. Besides, he was a personal friend of Pope Urban.No way did they think he was a hermetic, let alone one of the dangerous sort like Bruno.
Of course, confusing together the stories of Galileo, who was a great scientist and rationalist who got slapped on the wrist by the Inquisition, and Bruno, who was a fanatical, mystical loon who got burned at the stake (some 30 years earlier), has long been a staple of the myth makers. They were very different in both their personalities and their ideas. Galileo was right, but he was prepared to deny it to save his skin; Bruno martyred himself (he was given three chances to recant, and refused them all) for a mass of nonsense.
Galileo was brilliant and arrogant, but he was not particularly heroic. He was on the make, probably trying to advance in his career from the post of personal philosopher to the Grand Duke of Florence to that of personal philosopher to the Pope himself. And the Church was not deeply opposed to heliocentrism. It just happened to be politically expedient for Pope Urban and some of his close associates to appear to be opposed to heliocentrism (indeed, to anything that might have looked radical and untraditional) at just the moment when Galileo was trying to advance his reputation by publishing a brilliant defense of this radical and controversial theory, trying to impress he man whom he believed (rightly, really) to be a radical, modernizing Pope.
