  • Galileo remained a devout Catholic-throughout his life.
  • “Afficliation-Catholic; It is known to everyone that Galileo was denounced to the Inquisition in 1615 and that he was tried and condemned by the Inquisition in 1633, living the rest of his life under house arrest.  All of this was for Copernicanism, not for any heretical  theological views.”
  • Today the Catholic Church does not consider heliocentricity or any of Galileo’s writings to be heretical.
  • Galileo is often remembered for his conflict with the Roman Catholic Church.  His controversial work on the solar system was published in 1633.  It had no proofs of a sun-centered system.
  • After the “trial “ and being forbidden to teach the sun-centered system, Galileo did his most useful theoretical work, which was on dynamics.
  • Galileo expressly said that the Bible cannot err, he saw his system as concerning the issue of how the Bible should be interpreted.
  • The invention of the telescope and the series of discoveries that resulted from it made Galileo famous. However, by supporting the theory of Copernicus he aroused opposition in important (Catholic) Church circles, and in 1616 he was ordered to refrain from teaching the Copernican hypothesis.  Galileo chafed under this restriction for  several years.
  • Galileo spent the next six years composing his most famous work, the Dialogue Concerning the Two Chief World Systems. This book was a masterly exposition of the evidence in favor of the Copernican theory, and the book was published in 1632 with the imprimatur of the Church censors.
  • Nevertheless, Church authorities responded in anger when the book appeared, and Galileo was soon brought to trial before the Inquisition of Rome on charges of having violated the 1616 prohibition.
  • it seems clear that many churchmen were unhappy with the decision to prosecute the eminent scientist. Even under the Church law of the time, the case against Galileo was questionable, and he was given a comparatively light sentence.
  • He was not, in fact, confined to jail at all, but merely to house arrest in his own comfortable villa in .  Theoretically, he was to have o visitors, but that provision of the sentence was not enforced.
  • His only other punishment was the requirement that he publicly recant he view that the earth moved around the sun.
  • Galileo is probably more responsible than any other man for the empirical attitude of scientific research.
  • He rejected the notion that scientific questions could be decided by reliance upon authority, whether it be the pronouncements of the Church of the assertions of Aristotle.
  • He also rejected reliance on complex deductive schemes that were not based on a firm foundation of experiment.
  • His scientific outlook was distinctly non-mystical; in this respect, he was even more modern than some of his successors, such as Newton.
  • Galileo, it might be noted, was a deeply religious man. Despite his trial and conviction, he did not reject either religion or the church, but only the attempt of Church authorities to stifle investigation of scientific matters.
  • Later generations have quite rightly admired Galileo as a symbol of revolt against dogmatism, and against authoritarian attempts to stifle freedom of thought. Of greater importance, however, is the role he played founding modern scientific method.
