Indeed, we can see here his own initial wonderment and the very simple excitement that he felt upon making a series of discoveries that, aside from being exciting, were clearly of exceptional and lasting scientific significance and would certainly earn Galileo a reputation as one of the most important astronomical observers of his time if not in all of history. However, we can also see how this initial awe quickly turned into logical questioning after Galileo underwent the observation of a great deal of further data culminating in the observed retrograde motion of the moons, which lead him to a state of extreme and earnest puzzlement about the state of the solar system.
Indeed, this state of puzzlement was understandably not long-lived, however, and Galileo again quite understandably brought to bear the not inconsiderable powers of his mind to the task of parsing the confusing string of data that his astronomical observations had yielded with regard to the retrograde motion of these new "planets" that his telescope had enabled him to discover. After a series of intriguing thoughts, reflections, and considerations, Galileo eventually came to the conclusion that the provenance of this strange retrograde motion was attributable not to some strange "occult" device but to the simple fact that these "planets" were like the moon orbiting earth except for the fact that they were instead orbiting Jupiter. Indeed, this conclusion excited him to no end:
therefore concluded, and decided unhesitatingly, that there are three stars in the heavens moving about Jupiter, as Venus and Mercury around the Sun; which was at length established as clear as daylight by numerous other subsequent observations. These observations also established that there are not only three, but four, erratic sidereal bodies performing their revolutions around Jupiter.
Galileo, as quoted in Baalke)
Indeed, it is important to consider briefly here the strength of Galileo's language, in which he above states that the conclusion he has reached that the satellites that he has observed are not heavenly bodies orbiting the earth at all, but rather four distinct bodies all of which were instead orbiting the much larger Jupiter, was one the Galileo reached, according to this own words, "unhesitatingly." Indeed, not only was this a conclusion, but something that, again according to his own words was "decided" for him. He had crossed from territory of working hypothesis to the realm of theory and then even further into the strata of fervent belief that these new objects were moons of Jupiter. Once Galileo had crossed the boundary, he had violated the current presiding principle about the shape and construction of the universe, which held that the earth was the center of the universe about which all other things orbited, because he had proven that other bodies orbited points other than the earth. Once this central principle was thrown out the window, there was no need to hold to the standard view whatsoever, and, thusly, Galileo began to embrace the Copernican view, which held that the planets orbited the sun -- which was a view that Galileo felt that the preponderance of the current evidence supported in a full and rationally considered, as well as scientific and methodologically sound, fashion. After this course of thinking, he understandably sided himself with the Copernicans, but, he also knew that, given the fact that the Copernican view was not only openly dismissed by the Church and the other powers that be of his day, but also that Copernican views were actively punished by threat of excommunication and death, Galileo attempted to tread lightly on the subject in his monograph in a fashion that might enable him to avoid coming under the suspicious investigation of Church powers. Nonetheless, as we all well know, he was, in fact, completely unable to do so, and, since the church felt him to be in violation of one of its ordained heresies, being, in this case, the heresy of holding the Copernican view, it brought him to trial for these crimes, and, in order to save his own life and spare himself so that he might do further research in astronomy and observe new and ever more important phenomenon, Galileo recanted, although he did so after a fashion that was uniquely his own.
Indeed, that the Church found Copernican views of the cosmos heretical and sought to prosecute and discourage them at every given turn in history is greatly evidenced by the very trial that they conducted of Galileo in which the...
