This is a story about Galileo Galilei. It's not the story about an enlightened scientist being persecuted by a narrow-minded Catholic Church because that story is (mostly) a myth. It's not a story about a great scientific genius either, though he was that (mainly). It's also not a story about someone being reincarnated with the soul of the old astronomer like the song by the Indigo Girls that, for a few weeks in '92, I thought was (almost) profound. (And I should point out that it not an original story but one that cribbed together from other sources.)
But like all good stories this one provides a (mostly) valuable lesson.
In Galileo's day, the predominant view in astronomy was a model first espoused by Aristotle and developed by Claudius Ptolemy in which the sun and planets revolved around the earth. The Ptolemic system had been the reigning paradigm for over 1400 years when a Polish Canon named Nicholas Copernicus published his seminal work, On the Revolution of the Celestial Orbs.
Now Copernicus' heliocentric theory wasn't exactly new nor was it based on purely empirical observation. While it had a huge impact on the history of science, his theory was more of a revival of Pythagorean mysticism than of a new paradigm. Like many great discoveries, he merely took an old idea and gave it a new spin.
Although Copernicus' fellow churchmen encouraged him to publish his work, he delayed the publication of On the Revolution for several years for fear of being mocked by the scientific community. At the time, the academy belonged to Aristotelians who weren't about to let such nonsense slip through the "peer review" process.
Then came Galileo, the prototypical Renaissance man, a brilliant scientist, mathematician, and musician. But while he was intelligent, charming, and witty, the Italian was also argumentative, mocking, and vain. He was, as we would say, complex. When his fellow astronomer Johann Kepler wrote to tell him that he had converted to Copernicus' theory, Galileo shot back that he had too--and had been so for years (though all evidence shows that it wasn't true). His ego wouldn't allow him to be upstaged by men who weren't as smart as he was. And for Galileo, that included just about everybody.
