“Letters on the Solar Spots” was made public in 1613. Copernicus’s theory was openly discussed in this letter (Galilei and Drake, 145). Copernicus proposed than an axis-revolving Earth circumnavigated around the heart of the universe, the Sun (Andrade, 120). Father Lorini, a Dominican friar and professor of ecclesiastical history in Florence, was among the first to criticize Galileo for his Copernican views (Linder). The Copernican theory contravened the belief of the Holy Scripture that the Earth was in the middle of the universe (Andrade, 125). Lorini used Joshua 10:13 and Isaiah 40:22 as support. Joshua 10:13 states that “So the sun stood still in the midst of heaven”. Isaiah 40:22 talks about “the heavens stretched out as a curtain” above “the circle of the earth” (Linder). Galileo’s “Letter to Castelli” in December of 1613 was a reply to the condemnation he received due to his beliefs about the Copernicus theory. Galileo proposed in the letter that certain things in the Scripture were not to be taken literally. This letter only increased the amount of criticism towards Galileo (Andrade, 125). Father Lorini then took the drastic step of getting the Catholic Church involved. Lorini sent an altered copy of “Letter to Castelli” to the Roman Inquisition. Lorini altered the text of the letter to make it appear that Galileo directly pronounced the Scriptures as false. Lorini was not the only enemy of Galileo however. Father Tommasco Caccini was also a staunch opponent of
Explain Galileo’s attempt to make science and religion compatible, with particular reference to methods of justification. How successful is he? Use Kuhn’s notion of incommensurability to investigate Galileo’s attempt to reconcile the propositions of science and religion.
In concordance with Christian doctrines, this system implies that heaven and the throne of God lie beyond the tenth sphere. On the other hand, during the first half of the 16th century, Polish cleric Copernicus developed an astronomical model which positions the motionless Sun at the center of the universe, with the Earth, the moon, and six other planets revolving at a constant speed around it. He argues that all stars were at rest and that their nightly movements are simply indications of the earth’s rotation. However, members of the Church, especially Protestants, who interpreted the Bible literally, refused to grant Copernicus credit for his theory. Nevertheless, once released among the population, the Copernican theory raised support from various scholars, a few of whom, such as Brahe, Kepler, and Galileo, went on to dedicate their career to solidify its legitimacy. With their use of mathematical reasoning, instead of antic philosophy, the Copernican theory finally became justified among the population. Pertaining to its influence among laypeople, the Copernican theory raised various questions against the
Galileo Galilei was a very influential and controversial astronomer, scientist, mathematician, teacher, and physicist. His life began in the sixteenth century and ended in the seventeenth, in which he penned several books that supported the Copernican theory of a heliocentric solar system. In the words of Drake S. (1957) “... the works of Galileo are well written, and throw light upon the origins of modern science…”(Pg. 2) Although Galileo was soon deemed a heretic by the Roman Catholic church, he continued diligently challenging Aristotelian thought and doctrine and expressing his support of the Copernican theory. As he continued to make discoveries that supported this theory, the church continued to label him as a heretic, and eventually
His more relaxed viewpoint on the interpretations of the Bible and scripture allowed him to accept the Copernican theory. He even justified his stance through principals. The first principle was called biblical limitation. “I should judge that the authority of the Bible was designed to persuade men of these articles and propositions which, by science, or by any other means than through the very mouth of the Holy Spirit.” This principle overall explained that the bible could only be understood and interpreted correctly by the Holy Mother Mary. This gave a justification against claims from previous scholars such as St. Aquinas and St. Augustine. These two scholars took ideas for the overall argument from interpretations of the Bible made from either themselves or those before them. Therefore, Galileo believed that the interpretations were false. This allowed for science to not come in conflict with Catholicism as no one truly understood it. Another principle was the priority of physical demonstration. This principle stressed more on the empirical evidence before scriptural evidence. For this principle, Galileo focused primarily on nature and this allowed him to protect the concept of the Copernican theory from the bible. Since he used empirical evidence on nature, it allowed him to determine that the sun was at the center of the universe. Thus, observation, a major part of scientific
In the midst of this, Cardinal Bellarmine wrote him a letter explaining why his ideas were not going to be accepted. He said: “But to want to affirm that the sun really is fixed in the center of the heavens and only revolves around itself (i.e., turns upon its axis) without traveling from east to west, and that the earth is situated in the third sphere and revolves with great speed around the sun, is a very dangerous thing, not only by irritating all the philosophers and scholastic theologians, but also by injuring our holy faith and rendering the Holy Scriptures false” (Document B). The Cardinal explains how Galileo is contradicting the teachings of the theologists, philosophers, and the Bible. Also, he is doing a dangerous deed because the Church was afraid of these contradicting ideas because they could have destroyed the perspective on the Church and caused a major decrease in power. Galileo contradicting the Church impacted the future by causing more people to begin and question the ways of life, leading to new
There were many who cited portions of scripture such as Joshua 10:13, which states “So the Sun stood still in the midst of heaven” (Joshua 10:13), and Isaiah 40:22, which states “he that stretcheth out the heavens as nothing, and spreadeth them out as a tent to dwell in.” (Isaiah 40:22), as pieces of holy evidence to refute and definitely disprove the heliocentric theory as truth. However, Galileo could not easily be written off as a rambling, heretical madman either, seeing as his theories were first proposed by Nicolaus Copernicus, who was “not only a Catholic, but a priest and a canon.” (Galileo, Letter to Christina, 2) Even if Galileo was not a respected member of the Church, Copernicus was, and if his theories had originally been proposed by a Catholic canon, then it was harder to dismiss his ideas as heretical. Additionally, Galileo himself frequently offered to present others with evidence of the truth of his theories, stating “to the leading philosophers of the faculty here…I have offered a thousand times of my own accord to show my studies…” (Galileo, Letter to Kepler).
Galileo Galilei was an Italian philosopher born in 1564. As an adult, he didn’t believe the universal geocentric theory of the planets and heavens which was established by the
When Galileo’s astronomical claims became public, it was a large blow to The Church. The Church claimed that he was undermining the power of Scripture. If it had publically accepted Galileo’s claims, the Church’s authority would be further questioned. By suggesting that the earth revolved around the Sun, Galileo was questioning centuries of what people regarded to be the “truth,” and this did not sit well with the Church leaders. However, he did explain that he was not questioning the Bible itself, but questioning the interpretation of the Bible by those in positions of spiritual authority.
Galileo Galilei was also a supporter of the Copernican Theory. Galileo believed the earth, and other planets, rotated on its axis around the unmoving sun. He used his new invention of the telescope to prove Copernicus’ theory. With the telescope, Galileo found sunspots on the earth’s moon, which gave proof to him that the heavens were not perfect and changeless but were more like the changeable earth. iv He also discovered Jupiter and the four moons that revolved around it. He only discovered one moon revolving around the earth. Galileo therefore stated if Jupiter were to revolve around the earth, then the earth would have to have at least four moons, and it doesn’t. v The Church objected Galileo’s theory because the Bible said the sun moved through the sky. Being totally rejected by the church, Galileo was forced to take back what he had written and was also prevented from any further teachings of his theory. Galileo was condemned by the Catholic Church for his ideas. The Church succeeded in silencing Galileo but couldn’t stop the advancements in science.
Still, his real roadblock began with the Catholic Church. In trying to comply with the increasing knowledge of the scientific world, the Church was compliant with people practicing science, and even disagreeing with the Bible, as long as they did not vocalize these beliefs. Pretending that the Earth orbited the Sun was in line, but saying that it was true was unethical. In 1613, Galileo published Letters on Sunspots, which explained the dark spots on the Sun’s surface and the orbiting of the Earth around the
The Letter to the Grand Duchess Christina, penned by the famous astronomer and theoretical thinker, Galileo Galilei, is considered to be the most significant insult of the ideology of the Catholic church during the Renaissance Period. The letter, which would eventually be published all over Italy, was a shot at the Grand Duchess for her criticism of Galileo’s heliocentric theory as a result to its contradiction of the hypotheticals found in the Holy Bible. Galileo simultaneously challenged the previous theories of influential astronomer Ptolemy as well as the Catholic church. The letter and Galileo’s role in the scientific revolution of this time period advanced the western intellectual tradition by influencing the general population to not only question the theories and ideology lectured by the Catholic Church but also their fidelity to the church altogether. Before Galileo could begin developing theories of his own, he first had to study the theories and ideology of his greatest role models, Ptolemy, Aristotle, and Copernicus.
In this article, Galileo Galilei explains how his thoughts and beliefs brought a group of professors, who strongly believe in the Bible, against him. They were in contradiction with Galileo’s support of the Copernican system that proves how the planets revolve around the sun and not around the earth, which isn’t written in the Bible. Although Galileo wasn’t
In the history of the Catholic Church, no episode is so contested by so many viewpoints as the condemnation of Galileo. The Galileo case, for many, proves the Church abhors science, refuses to abandon outdated teachings, and is clearly not infallible. For staunch Catholics the episode is often a source of embarrassment and frustration. Either way it is undeniable that Galileo’s life sparked a definite change in scientific thought all across Europe and symbolised the struggle between science and the Catholic Church.
Even though Galileos beliefs were held in practicing Catholicsim, his writings were showing evidence for “Copernican heliocentrism.” The Catholic Church, however, disapproved of heliocentricity, feeling that it was contrary to the statements in the Bible: if God created human beings as His supreme creation, He would place man at the center of His cosmos. (At that time the more literal Biblical interpretation was prevalent with the church fathers, especially among the Dominican Order, facilitators of the Inquisition)2 However, real power layed with the Church, and Galileo's arguments were most fiercely fought on the religious level. Cardinal Robert Bellarmine insisted that Galileo furnish more adequate proof of his new theories before he would be allowed to teach them as true or even as probably true.
There are at least three separate justification-type questions surrounding the condemnation of Galileo. First, was the Roman Catholic Church justified in accepting Ptolemy over Copernicus? Second, was it justified in issuing the injunction against Galileo in 1616? And third, based on the injunction, was it justified in condemning him in 1633? There may be further ethical and methodological questions surrounding the Church’s actions in Galileo affair, but these will be extrinsic, 21st century questions that a good Roman Catholic of the time would have considered settled. It is these three that will help us understand things from a 17th century Catholic perspective. I will defend the position that while the evidence for Copernicanism was not
