PHIL 3710: Honors History and Philosophy of Science, Part 1: from Aristotle to Galileo

Dr. Timothy McGrew, Fall 2012

 

Required and Supplementary Texts: The following texts are required:

 

McGrew, Alspector-Kelly, and Allhoff, eds., The Philosophy of Science: An Historical Anthology, hereafter abbreviated as PS

 

Galileo Galilei, Dialogue Concerning the Two Chief World Systems, hereafter abbreviated as Dialogue

 

Additional reading may be handed out in class or made available online at the course webpage:

 

http://homepages.wmich.edu/~mcgrew/honhps1 2012.htm

 

In addition, material will be presented in class lectures that is unavailable in any other form. All of this additional material is fair game for tests and quizzes.

 

The readings for each week sometimes contain supplementary reading that may be useful but is not required. The principal sources for this reading are:

 

Carl Boyer, The History of the Calculus and its Conceptual Development (1959)

 

I. Bernard Cohen, The Birth of a New Physics, 2nd ed. (1985)

 

Michael Crowe, Theories of the World from Antiquity to the Copernican Revolution, 2nd ed. (2001)

 

Samuel Sambursky, The Physical World of the Greeks (NY: Collier, 1956)

 

Stephen Toulmin and June Goodfield, The Fabric of the Heavens (1999)

 

All of these books are available in the Waldo Library.

 

Course Description: This course is an exploration of themes in the history and philosophy of science, with special attention to the life and work of Aristotle, Ptolemy, Copernicus, Tycho, Kepler and Galileo. Beginning with the necessary background in the physics and astronomy of Aristotle, we will study the development of the modern view with an eye to the conceptual and epistemological problems encountered in the transition to the new physics and astronomy, culminating with a close reading of most of Galileo’s Dialogue Concerning the Two Chief World Systems. In order to keep the course within manageable bounds, we will focus primarily on astronomy and dynamics, though there will be interesting sidelights thrown on mathematics as well as biology, chemistry and other branches of science.

 

Course Requirements: This course meets Tuesday and Thursday of each week from 2:00 p.m. to 3:15 p.m. except for the days noted on the course schedule. I expect you to arrive on time; a pattern of late arrival will be reflected in your course grade. Late assignments cannot be made up without a medical excuse except in very unusual situations. Because important material for papers and quizzes may be presented in class lecture that cannot be found elsewhere, it is imperative that you come to class and take careful notes. You are responsible to obtain notes from another student in the class if you miss a day.

 

Attendance and quality (but not necessarily quantity) of class participation are taken into account in the determination of the final grade. In particular, I reserve the right to subtract five points from the final grade for each unexcused absence beyond the third.

 

There is a fair amount of reading assigned for this course. This includes a large number of primary sources—documents that were written by philosophers and scientists to describe their speculations and experiments rather than simplifications written by journalists or popularizers. These are the documents from which the history of science is constructed. Most of them do not require specialized knowledge beyond the occasional use of a bit of geometry or high school algebra, but they do require concentration. Students are expected to come to class having already done the reading indicated on the syllabus and may be subjected to unannounced quizzes on that material.

 

General Education: This course may be used to satisfy General Education Area VII (Natural Science and Technology).

 

Electronic Devices: The use of electronic communications and media devices, including but not limited to CD players, iPods, handheld games, cell phones, and laptop computers, is forbidden during class time. Digital or tape recording devices may be used to record class lectures and discussion with the permission of the instructor. Cell phones must be turned off. If your cell phone rings during class, you will be required—without answering it—to speak for five minutes regarding the assigned reading for the day, and the quality of your presentation will be taken into account in the determination of your final grade for the course.

 

Academic Integrity: You are responsible for making yourself aware of and understanding the academic policies and procedures in the Undergraduate Catalog (http://catalog.wmich.edu) that pertain to student rights and responsibilities. These policies include cheating, fabrication, falsification and forgery, multiple submission, plagiarism, complicity, and computer misuse. If there is reason to believe you have been involved in academic dishonesty, you will be referred to the Office of Student Judicial Affairs. You will be given the opportunity to review the charge(s). If you believe you are not responsible, you will have the opportunity for a hearing. You should consult with me if you are uncertain about an issue of academic honesty prior to the submission of an assignment or test.

 

Accommodation for disabilities: Any student with a documented disability (e.g., physical, learning, psychiatric, vision, hearing, etc.) who needs to arrange reasonable accommodations must contact the disability office at 387-2116 at the beginning of the semester. I am not allowed to make any accommodations for disability until you have obtained appropriate documentation from this office.

 

Assignment Weight Breakdown: The various components of the course will count toward your final grade according to the following weights:

 

Best Essay Score:

0.25

Other Essay Scores:

0.40 (0.20 each)

Reading Questions

0.40 (0.10 each)

 

A moment’s calculation will show that these weights add up to 1.05 (105%) rather than 1.00. This provision builds in a small measure of extra credit. In addition, each student’s best exam score is given slightly more weight than the other two scores. There will be no other opportunities for extra credit.

 

Grading Scheme: All assignments will be graded on a 4 point scale—that is, from 0 to 4 inclusive. While there is great variability in the qualities that make for a particular grade on a given assignment, the following guidelines will give you some idea of how the scale works:

 

A 4 indicates a performance of exceptional quality. The student has not only demonstrated mastery of all the material necessary to complete the assignment but also presented it clearly. The writing is at a high standard.

 

A 3 typically indicates a consistently strong performance, though the work may be lacking in some details or in a particular aspect of the assignment or may suffer from occasional substandard writing.

 

A 2 typically indicates minimal satisfactory performance. The student has demonstrated some understanding of the core concepts, but there are significant errors, gaps in comprehension, or flaws in the writing.

 

A 1 typically indicates an insufficient performance. The student has demonstrated a small amount of understanding, but there are serious deficiencies in the work submitted.

 

A 0 indicates a performance that has failed to demonstrate even a rudimentary understanding of the material on which the assignment is based or has failed to exhibit even the most elementary writing skills.

 

A score of -4 indicates that the student did not complete the assignment or did not complete the assignment in a minimally reasonable manner. (Anyone who makes an honest effort to complete an assignment will find it very difficult to earn this score.)

 

Grades somewhere between two of the above marks may be given if, in my judgment, the work falls somewhere between two of the levels above.

 

The following grading scale will be used for this course:

 

≥ 3.75

A (93-100)

1.75-2.24

C (73-77.9)

3.25-3.74

BA (88-92.9)

1.25-1.74

DC (68-72.9)

2.75-3.24

B (83-87.9)

0.75-1.24

D (60-67.9)

2.25-2.74

CB (78-82.9)

< 0.75

E (< 60)

 

As noted above, I reserve the right to give a negative score (as low as -4) for assignments not submitted or submitted but done in a manner demonstrating less than reasonable effort.

Course Schedule

 

The following schedule is tentative. Because the material is difficult, some of it may take longer than the indicated time. You are expected to do the readings in accordance with the sequence of topics even if we are off schedule. Any alterations in exam dates will be announced in class ahead of time.

 

Readings must be done, and assignments must be completed, before the date indicated; that is, you should come to class having done the reading and completed the assignments for that day. Videos are optional unless otherwise stated.

 

Some of the links for handouts will not become visible until the appropriate time in the semester. You should check the web address at least weekly. If a link is not working for you and you think that it should be, you should email me immediately.
