I don’t want to sound like the Antichrist here, and I certainly do not contest the fact that the majority of the Church must have been well-intentioned clerics busy helping people, transcribing books, or tending their gardens (of course, there were the fanatics, the zealots, the war-crazy, the power-hungry, the Templars, Hospitallers, etc. as well…). My real problem lies with the excessive power wielded by the Church on a political level, and hence in the upper echeleons of Church organizations. Why should the Church have been allowed to go after Galileo at all? Why were so many of the top officials of the Church so rich for so long? Why the hell were the various Inquisitions ever allowed to take place? The answer seems to be “Excessive power”.
As far as I am concerned, and I agree that there are obviously many opinions on this, Galileo proved with his telescope and calculations what Copernicus proved with his remarkable intuition and intelligence.
Copernicus: his heliocentric theory accounted not only for the apparent motion of the sun, which is otherwise difficult to reconcile with what the Greeks already knew about the sphericity of the Earth and astronomy, but it also accounted for the curious “retrograde” orbits of some Planets. Without heliocentrism the planets would have been wobbling back and forth on their paths in a very curious manner.
Galileo: When he aimed his telescope at Jupiter and observed that system, with its orbiting moons, he was able to devise the workings and plausibilities of the greater system that Copernicus had envisioned. Then, again with his telescope, he discovered the phases of Venus, which could only be explained sensibly by the use of a heliocentric system. He also made several important discoveries using the pendulum method. This evidence together with the work of Copernicus and further calculations forms a pretty damn good case for heliocentrism–yet it was all rejected by the Church for as long as Galileo lived and a good while after he died.
This strikes me as a precursor to the O.J. Simpson trial: wasn’t it ridiculous how, in spite of all the evidence provided, the O.J. defense kept arguing that more evidence was needed? How much more evidence did the Church need before admitting defeat in the argument?? Wait–Doctrine might be involved here, that same beast that decided you were a witch if you floated in a pond, and innocent if you drowned?
The issue of stellar parallax is a particularly obnoxious one to raise, because stellar parallax was not observable at the time of Galileo.
Lunar parallax was observed and calculated in 190-150 BC.
Solar Parallax was not observed with any reasonable accuracy until 1672!!
Stellar Parallax was practically a lost cause until the introduction of the photographic method in 1903! Wasn’t the Church asking a bit too much of Galileo in 1633??? To observe stellar parallax two things are required: an accurate and powerful telescope, and a sufficiently wide baseline. The telescope Galileo had was not sufficiently accurate nor powerful. The Church’s requirement of stellar parallax was an O.J. Simpsonism, a term I coined 2 seconds ago and which means: “an excessive and unnecessary request for evidence that, owing to difficulty or impracticality in gathering the evidence, may affect a debate along lines planned by the party making the request”.
Galileo filled many of his books with calculations derived from a large number of thought and real experiments that prove his points. This point was contested, but eventually proved when Galileo’s notes were found. He wrote mathematical assertions in his book and avoided writing about many of the experiments themselves because in his day mathematics was already one of the most assertive scientific languages. The Church was presented with all the proof required to make at least a preliminary hypothesis, but someone in the Church organization had made a decision on Doctrine before Galileo put pen to paper. Do we need to blame the Church as a whole if the actions were those of a handful of men, as could be possible? That depends on how accountable the Church is for the actions of its more powerful members–I for one believe the Church should be accountable, especially after it failed to do anything about this travesty for several years.
Finally, very recently in this Century, the church formally admitted its error in forcing Galileo to deny the evidence of his own senses. The Church employed the wrong methods, and they acknowledged it. I’m not sure where the anti-Galileo apologies are coming from, but they do not seem to be coming directly from the Church, the body that has the most records on its activities and that has already admitted its errors. Galileo was not endowed with a perfect character but his experiments, calculations, and conclusions were certainly not incorrect or inconclusive. They were merely in need of some refinement.
After having examined a number of sources as well as many of the very illuminating posts on this thread, my conclusion remains: in the Galileo issue the church was most definitely guilty of suppressing valid science.
PS: Apologies for my blunder concerning the Mini Ice Age; it did indeed start in the 1500s or thereabouts, and not earlier.
