Galileo: Bridging Religion and Natural Philosophy

1967 Words4 Pages

Throughout his various works and discoveries, Galileo makes a distinction between religion and natural philosophy that holds up beyond his personal feelings, proven through his various works and discoveries. The Aristotelian view of the universe was based upon a common sense argument that gave credit to many discoveries throughout antiquity. Those discoveries were based upon a mix of science and scripture that was regarded as fact. Galileo brings something different to the table, the notion of observation. In appealing to observation, Galileo is able to make a clear distinction between religion and natural philosophy that is credible beyond his personal beliefs.

In order to distinguish between religion and natural philosophy, Galileo appealed to the centuries old sentiment of observation. If people were able to reproduce or procure their own instrument such as the telescope, they could simply observe the craters and shadows of the moon themselves. People would be able to observe the change in the appearance of the lunar surface in connection to how it was struck by the suns rays (Biagoli 2006, 106). In a broad sense, Galileo was able to build what we would call the basic elements of science today, validity and replicability, which allowed him to divide religion and …show more content…

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
