As humans we will always be challenged in our daily lives. When we have a view on something we may have to fight to prove its validity. Some of us may be able to do it on our own but many of us will need a helping hand. Nicolaus Copernicus was this type of man. He developed a theory of a sun centered or heliocentric solar system that went against the current popular belief of an earth centered or geocentric solar system. It took many centuries for the world to accept his theory. Kepler, Galileo and Newton were strong proponents to the Copernican model and continued to advance his research where they later proved that a heliocentric solar system was a correct model. Although Copernicus’ views suffered great backlash, he became the prime mover in the scientific revolution and the paradigm shift from the model of a geocentric universe to a heliocentric universe.
The work of Aristotle and of Ptolemy set the standard for the model of the geocentric solar system around 150 A.D. Ptolemy’s work was known as the Almagest, which is an Arabic word for great synthesis. His work was given this title because “it is a synthesis of all astronomical and cosmological knowledge (the structure of the universe) accumulated since Aristotle. Ptolemy's work is therefore based on the Aristotelian representation of the universe.” [2]. He developed a geocentric model consisting of concentric spheres with the Earth at the center and each planet, the sun and fixed stars existing on the edge of their own sphere. Everything existing within the outermost sphere was considered to be the domain of the Prime Mover. The Ptolemaic Universe was considered to be the proper model and was used as the prime reference for many centuries of teachings and beliefs.

During the Scientific Revolution, the struggle between faith and reason was exhibited through Galileo and his discoveries. The Catholic Church during the time period of the Scientific Revolution did not approve of any outside scientists who came up with new theories and observations. The Church believed that all information about how the world worked was in the bible and that was the only right source. In an excerpt from “What is Scientific Authority?” written by Galileo in 1615, it states, “Showing a greater fondness for their [Catholic Church’s] own opinions than for truth, they sought to deny & disprove the new things which, if they had cared to look for themselves, their own senses would have demonstrated to them…” Galileo Galilei himself knew that the Church was not willing to approve of new ideas from other scientists, but only from the teachings in the Bible. Later on in the excerpt, Galileo writes, “They [Catholic Church] hurled various charges &…made the grave mistake of sprinkling these with passages taken from places in the Bible which they had failed to understand properl...
In papal Rome in the early 16th century the “Good Book” was the reference book for all scientists. If a theory was supported in its holy pages, or at the very least not contradicted, then the idea had a chance of find acceptance outside the laboratory. Likewise, no theory no matter how well documented could be viewed with anything but disdain if it contradicted with the written word of, or the Church’s official interpretation of scripture. For these reasons the Church suppressed helio-centric thinking to the point of making it a hiss and a byword. However, this did not keep brave men from exploring scientific reason outside the canonical doctrine of the papal throne, sometimes at the risk of losing their own lives. While the Vatican was able to control the universities and even most of the professors, it could not control the mind of one man known to the modern world as Galileo Galilei. Despite a wide array of enemies, Galileo embarked on a quest, it seems almost from the beginning of his academic career, to defend the Copernican idea of a helio-centric universe by challenging the authority of the church in matters of science. Galileo‘s willingness to stand up for what he held to be right in the face of opposition from Bible-driven science advocates set him apart as one of the key players in the movement to separate Church authority from scientific discovery, and consequently paved the way for future scientific achievement.
In his Letter to The Grand Duchess Christina, Galileo challenged the widely accepted religious beliefs of the time, claiming that the conflict lies in their interpretation, not the context. In Galileo’s eyes science was an extremely useful tool that could and should have been used in interpreting the Scriptures. He argued that “the intention of the Holy Ghost is to teach us how one goes to heaven not how heaven goes” (Grand Duchess). The purpose of science was not to counter what the bible teaches; rather its purpose was to help explain the teachings of the scriptures. Furthermore, it was “prudent to affirm that the holy Bible can never speak untruth-whenever its true meaning is understood” (Grand Duchess). However, because of the terminology in which the bible was presented the perception of what the Scripture defined as truth was skewed. The Bible was written so that the common man could understand it and follow its commandments. The people also showed a greater inte...
...cided to condemn Galileo’s work. While it does not discredit God’s power or the Bible, the overall tone of the scientist’s letter is quite sarcastic towards the clergy. While defending his first argument, Galileo appears to undermine the intellectual capabilities of his opponents. He implies that those who interpret the Holy Writ word for word belong to the “common people” whom he describes as “rude and unlearned”, and that other “wise expositors” should be the ones who search for the true meaning of the Bible. Galileo makes a similar implication while presenting his second argument, when he writes that the purpose of the Holy Scriptures is “infinitely beyond the comprehension of the common people”. The Catholic Church likely viewed these claims as an attempt to weaken its authority, which would explain why Galileo’s discoveries were condemned for nearly 300 years.
One excerpt is from the previously mentioned Dialogue of the Two Chief World Systems (1632) in which Galileo debates the arguments of Aristotle and Potelmy against those of Copernicus through three characters, Salviati, Sagredo and Simplicio. On day three of the arguments, Salviati, Sagredo and Simplicio debate heliocentrism. Simplicio applies to Ptolemy’s zodiacal philosophy in claiming that the earth is the center of the universe: “…if the terrestrial globe should move in the course of a year along the circumference of a circle, namely, along the zodiac, it would be impossible for it to be simultaneously at the center of the zodiac” (Finnochiaro 2008, 234). In retaliation, Salviati appeals to observation. He says that all the planets are sometimes different distances from the earth. Salviati states that Aristotle was wrong in his thinking that all the planets are an equal distance from earth (Finnochiaro 2008, 236). To explain his point in more detail, Salviati has Simplicio draw a diagram according to the observation of the heavenly bodies. “… the heavenly bodies have been arranged just as in the Copernican system, and you have done this yourself” (Finnochiaro 2008, 240). In the Dialogue, Galileo has Salviati use observation to explain to Simplicio that recent discoveries are more in line with the Copernican view and that in turn, heliocentrism should be seen as more credible and valid in the scientific
Nicholas Copernicus was the first to question the universal truths and teachings of the church. He devised a theory that the earth along with the other planets revolved around the sun. This theory disagreed with Aristotle and the old teachings that the universe revolved around the earth, and that man was the center of the universe.
A key parallel between the scientific revolution and the enlightenment was the decreasing belief in authority. The scientific revolution lead to great advances in astronomy, mathematics, geography, botany and medicine (7). A key discovery was that of Copernicus’ heliocentric theory (2). The heliocentric theory proposed that the sun was at the centre of the universe as opposed to the earth which was the common belief held strongly at the time. Copernicus discovered that the sun was at the centre of the universe, and that the moon orbited the earth while the earth orbited the sun. This theory raised profound qu...
Galileo was born in 1564 in a time where society was very conforming to the teachings of the church. Despite his discoveries, Galileo was very religious though he tied religion and science into his life. Galileo’s great contribution to science was the telescope, however his greater contribution was the gift of awareness and knowledge. Before Galileo, it was generally accepted that the earth was the center of the universe. This was not based upon data or facts, but merely because the church said so. Prior to the seventeenth century, Europe was stuck in the med-evil era of church teachings. With Galileo’s telescope, however, he was able to show that the sun rather than the earth was the center of the universe. Although this new discovery had a large scientific value, it had a larger impact to society on a religious level.
To the modern reader, Aristotle's views on astronomy, as presented in Metaphysics, Physics, De Caelo (On the Heavens) and Simplicius' Commentary, will most likely seem very bizarre, as they are based more on a priori philosophical speculation than empirical observation. Although Aristotle acknowledged the importance of "scientific" astronomy - the study of the positions, distances and motions of the stars - he nevertheless treated astronomy in the abstract, linking it to his overall philosophical world picture. As a result, the modern distinction between physics and metaphysics is not present in Aristotle, and in order to fully appreciate him we must try to abandon this pre-conception. Aristotle argued that the universe is spherical and finite. Spherical, because that is the most perfect shape; finite, because it has a center, viz. the center of the earth, and a body with a center cannot be infinite. He believed that the earth, too, is a sphere. It is relatively small compared to the stars, and in contrast to the celestial bodies, always at rest. For one of his proofs of this latter point, he referred to an empirically testable fact: if the earth were in motion, an observer on it would see the fixed stars as moving, just as he now observes the planets as moving, that is from a stationary earth. However, since this is not the case, the earth must be at rest. To prove that the earth is a sphere, he produced the argument that all earthly substances move towards the center, and thus would eventually have to form a sphere.
In 1513, Nicholas Copernicus, composed a brief theory that stated that the sun is at rest and the earth is in rotation around the sun. In 1543, just days before his death, Copernicus published this theory in On the Revolutions of the Heavenly Spheres. This theory was meant to dissolve the long lived belief in Ptolemyís theory which stated, "The earth was at the center because it was the heaviest of objects(Kagan331)." This was a common belief at that time, which supported the religious beliefs that the earth was the center of the universe and God in the heavens were surrounding the earth. Copernicusís theory was shocking, but he published such a controversial theory without sufficient evidence, it had to be considered invalid.
Much to the dismay of the Church, two astronomers Galileo and Kepler had the audacity to challenge the authorities by suggesting that the sun-not the earth-was at the center of the universe. The church had a stronghold on the way the spiritual and physical world worked, so these discoveries only added to the Church’s resistance to their aims. Their discoveries came only after Kepler and Galileo began to question ancient theories about how the world functioned. These ancient truths were widely held but were inconsistent with the new observations that they had made. Kepler had discovered the laws of planetary motion which suggested that the planet would move in elliptical orbits, while Galileo followed with his discovery of the principle of inertia. Galileo concluded his finding b...
Democritus was the leader of a group called Atomists. Although they were unable to prove that matter was made up of small particles, they were the first to come up with the idea. Democritus believed that atoms differed in size, shape, and movement but were all made of the same substances. Aristotle was the most important scientific philosopher in Greece. He believed that all matter on earth consisted of four pure substances or elements, which were earth, air, fire, and water. He also believed that the earth was the centre of the universe, and that anything beyond the earth consisted of a fifth pure substance called quintessence. Archimedes was an inventor and mathematician, who discovered several basic scientific principles and developed a number of measuring techniques. Ptolemy was an Egyptian astronomer. He developed a model for predicting the positions of the sun, moon, stars, and planets. Like Aristotle, he believed that the earth was the center of the universe. Between 400 AD. and 1000 AD.
The expansion and endorsement of intellectualism by the many important forward thinking scientists created a desire for social revolution, which, in turn, created an atmosphere conducive to further intellectual study. The Scientific Revolution was, in essence, both a social and intellectual revolution. During the Scientific Revolution, scientists such as Nicolaus Copernicus, Galileo Galilei, Francis Bacon, Rene Descartes, and Christiaan Huygens wrestled with questions concerning God, human intellectualism, and their scientific views of the universe, its purpose, and how it functions. Ultimately, the implications of these new scientific discoveries began to change the way people thought and behaved. People began to question the widely accepted and Roman Catholic Church endorsed Aristotelian views of the universe. This led to the questioning of the traditional views of the state and societal structure. The geocentric Ptolemaic model was no longer blindly accepted. The earth was now no longer easily explainable or thought to be the center of the universe. Beliefs that were hundreds of years old were now proven to be false.
The cosmological views of the Late Middle Ages revolved around the Aristotelian-Ptolemaic theory. This theory was adapted by the Church to explain the universe, as a result, many people believed the Aristotelian-Ptolemaic theory was perfect because the pope believed it, and he was infallible. The Church took many ideas from the Bible. One example would be that they believed that the universe was six thousand years old. Another major idea was that the universe was made up of a series of concentric spheres with a motionless earth at the center. Planets, commonly referred to as “heavenly bodies”, were made up of crystalline substance and moved in circular orbits. Stars are attached to these planets and are “pushed by angels”.
Nicholaus Copernicus is one of the most well known astronomers of all time. He is even labeled as the founder of modern astronomy for the proposition of his heliocentric theory (“Nicolaus Copernicus”, Scientists: Their Lives and Works). The heliocentric theory was revolutionary for Copernicus’ time. Copernicus lived during the Renaissance. “The era of the Renaissance (roughly 1400-1600) is usually known for the “rebirth” of an appreciation of ancient Greek and Roman art forms, along with other aspects of classical teachings that tended to diminish the virtually exclusive concentration on religious teachings during the preceding centuries of the “Dark Ages.” New thinking in science was also evident in this time…” This time period became known as the scientific revolution (“Copernicus: On The Revolutions Of Heavenly Bodies). In other words, old ideas were revived in the arts and other means and less emphasis was placed o...
