Homework 4, Due Nov 30, 2012

Welcome back from Thanksgiving break! Only a few weeks left in the semester, so be sure to keep up with your assignments! We'll be studying some very interesting history over the next few weeks, and I know you'll be interested in some of the individuals we discuss. One such individual is a true "Renaissance Man" - Galileo.

As most of you already know, Galileo was, among other things, a scientist who was tried for an unusual crime (by today's standards) - teaching "non-biblical" beliefs, namely that the earth orbited the sun! Although he was convicted and forced to publicly declare that he had been wrong, he was never tortured or imprisoned (his principle punishment was the requirement that he do penance, which his daughter did for him). Since no equipment had been invented that allowed anyone to see the orbits, both sides based their arguments on other things, such as math (both sides were wrong) and the interpretation of scriptures. So how did this get started?

As we learned previously, the discovery of ancient Greek and Roman history by the Crusaders absolutely revolutionized Europe. In a few short centuries Europe would go from being woefully primitive in comparison to the Arabs, Chinese and Indians (people from India), to being the dominant military, commercial, and educational force in the world. However, it's important to point out the the ancient Greeks and Romans weren't exactly foolproof - their own information was sometimes nothing more than an educated guess. The biggest perpetrator was Aristotle himself. The great man is responsible for so much wisdom and creativity, but his greatest contributions to history are probably the things he got wrong! For example, he believed that the heart circulated air through the body, not blood. For centuries, despite the increasing evidence to the contrary, many people refused to accept the fact that Aristotle was wrong. And he had another guess that was wrong also - the order of the universe.

Aristotle was at least inciteful enough to realize that many of the ancient myths about the night sky were wrong, but he was responsible for convincing many people that the earth stood still and the sun, moon and stars orbited around it. The Egyptian astronomer Ptolemy claimed to have proof that Aristotle was right (therefore the earth-centered theory was called the Ptolemaic Model). When this theory was brought back from the Crusades in the 1300s, many Europeans automatically accepted that it was true, and even found scripture that, the believed, backed up his assertions. For example, Psalm 93:1: “Thou hast fixed the earth immovable and firm ...” and Psalm 96:10: “He has fixed the earth firm, immovable ...”.

Although the 16th century astronomer Copernicus described a "heliocentric", or sun-centered, universe as being the only model that explained the movement of the stars, by the time people were exposed to this view the Ptolemaic Model was considered sacred. When Galileo Galilei came along, he wrote a book called "Dialogues Concerning Two New Sciences" in which he had two smart characters (one believed the Copernican Model, the other was smart enough to listen to him) and one character that was obviously supposed to be simple (named Simplicio), and he argued for the geocentric model with ridiculous and shallow arguments. It was open opposition to what the Catholic Church held to be true, and the dumb character seemed to resemble the Pope (Galileo's longtime, and soon to be ex-, friend).

Galileo's trial in the 1630s was complex because a great deal of politics was involved and ended in the manner I mentioned earlier. Within fifty years of his death the Catholic Church reversed its decision and embraced the Copernican Model (of course, we know now that neither the sun nor the earth is fixed, nor is our solar system the center of the universe). Why it concerns us today is that we still face questions about the compatability of scripture and science. While many people today embrace faulty science in order to argue that the Bible isn't true, we Christians have seen over and over that science proves the Bible's teaching.

Your assignment this week is to consider the story of Galileo and answer the following questions: How should Christians have acted toward the Copernical Model in the 1600s, and why? If the scriptures in Psalms do not imply that the earth literally stands still, what do they mean? (you'll need to read the verses around them for context). And, finally, what can Christians do today to ensure that mistakes like these don't occur again?

I look forward to reading your answers. The requirements for this assignment are exactly as those that have preceded it. Thanks and have a good week!
