1. Course Description
The various sciences each have a subject matter—biology, in particular, studies the processes involved in living organisms. Philosophy of biology likewise has a subject matter—biology itself. As a part of philosophy of science, a major part of the goal in philosophy of biology is to understand the ways in which biologists produce knowledge. This inquiry addresses such questions as: What kinds of explanations do biologists provide? How do the explanations of biology relate to those of physics and chemistry? A distinctive feature of biology is that the phenomena it studies have evolved. How can we know about the history of living systems and the processes that shape evolution? Our investigation of biology will look both at its history and its contemporary practice. The reason for turning to its history is that many of the fundamental ideas that guide contemporary biology were developed over the last 200 years and can be identified more crisply during the historical development of modern biology. Thus, we will consider the development of cell theory, physiological chemistry, evolution, and genetics in the 19th century. Many of the same theoretical and conceptual issues that biologists confronted in the 20th century continue to be the focus in contemporary biology, especially those concerned with the mechanisms responsible for biological phenomena and their evolution. To ground our discussion of the contemporary period we will focus on research on one biological phenomenon--circadian rhythms. Students are invited and encouraged to draw upon their own knowledge of biology and its history in class discussions.
Given the nature of the class, substantial material will be presented in lectures that goes beyond what is included in the readings. Also, philosophy is an activity, and learning activities requires active engagement. Accordingly, class attendance and discussion is critical. Although we will have discussions on other occasions as well, several classes are designated as discussion classes and the topics for discussion in these classes will be determined by students.
2. Course Requirements
Class attendance is mandatory. Missing classes more than very occasionally will result in a reduction in your grade. To get the most out of the class, it is absolutely essential that you come to class having read the assigned material and prepared to discuss it. Questions will be posed in each class to be answered using Clickers. Some clicker questions will test basic ideas from the assigned reading. On these questions, one point will be awarded for ansering the question and a second point for answering correctly. Other questions will not have a specific answer designated and will serve to foster discussion. Two points will be awarded for answering each such question. A commulative score based on clicker responses will count for 10% of your final grade.
To promote engagement with the reading and to foster subsequent discussions in class, you will be required to email comments or questions on the reading assigned for those classes marked with an asterisk on the Schedule of Class Meetings and Readings below. These emails should be one paragraph in length. You can write about anything you found interesting, puzzling, strange, clearly wrong, provocative, etc. These will be graded as acceptable or unacceptable. To ensure that your submission is acceptable, your comment or question must demonstrate that you have read and thought about the assigned material. (Your paragraph may focus on one specific part of the reading--do not try to discuss everything.) These must be submitted as email (as plain text, not as attachments) to email@example.com by 7AM on days marked with an asterisk in the schedule of classes below. 10% of your final grade will be based on these email comments.
There will be two exams, a mid-term and a final. The mid-term will count for 25% of your final grade; the final will count for 30%. Exams will include both short answer and essay questions and the set of questions will be distributed approximately one week before the exams. You will also need to write one 3-5 page paper that will count for 25% of your grade. The paper, due by NOON on Friday, November 22, must be on one of the topics that will be assigned in class. If possible, the paper should be submitted in Word by email attachment (please be sure to check for viruses before submitting your file!) to firstname.lastname@example.org.
Above average or below average participation in class discussions can result in a raising or lowering of your final grade from what is determined by the above percentages on these other assignments.
All of the reading assignments can be found by following links on the web site. See the schedule of classes and readings below. Those items that are on license to UCSD may only be available if you are on campus or set up a virtual private network (directions on doing so are avaiable through Academic Computing Services).
If you do not already own one, you will also need to purchase an i>clicker student response transmiter. These transmitters, informally called “clickers,” are available at the UCSD bookstore. Make sure to get an i>clicker and not a different system (e.g., H-ITT or PRS). For more information, visit http://acms.ucsd.edu/services/classroom-support/clickers.html.
4. Academic honesty
Integrity of scholarship is essential for an academic community. The University expects that both faculty and students will honor this principle and in so doing protect the validity of University intellectual work. For students, this means that all academic work must be done by the individual who submits, without unauthorized aid of any kind. This means that on exams you will not use any external resources, including crib sheets, cell phones, etc. All papers, emails, etc., that you submit must be written by you in your own words. If you need to quote someone, be sure to use quotation marks and identify the source. In preparing for exams, papers, etc., you are encouraged to work with your peers. But the actual writing must be yours. You may ask others to read and provide feedback on your writing, but they should not re-write the text for you. Rather, they can provide comments and you undertake the rewriting.
5. Email List
There is an email distribution lists for this course. It is required that you subscribe to this list. Do it IMMEDIATELY. You can always unsubscribe later if you drop the course. The purpose of the list is to allow me to distribute information regarding due dates for assignments, changes of schedule, etc. Some of this information is crucial, and some of it may be distributed early on. To subscribe, you simply need to send an email message with Subscribe in the header to the following address: email@example.com. After you send the subscribe request, you will receive a reply from firstname.lastname@example.org that will ask you to confirm your request. Follow the directions in this message to confirm you subscription. If you later want to remove yourself from this list, send email with the header Unsubscribe to email@example.com. At the end of the course I will unsubscribe everyone on the list so you do not have to do this. Once subscribed, you need to check your email regulary--once I have distributed information my email, it is your obligation to read the email.
Only I have authorization to send mail to this list. There should be no spam. If you receive mail from this list that is not from me, be assured that I will as well and will take measures to block further abuse. (The welcome message you receive suggests that you can send email to the list. Sorry, but you cannot. If there is interest in setting up a voluntary discussion list for the class to which anyone can submit, I am happy to do so, but participation will not make it required.)
6. Schedule of Classes and Readings
Note: This schedule of reading assignments is tentative and subject to revision. When powerpoints from lectures are available, there will be a link from the lecture title to the pdf file. Dates with asterisks are dates on which comments/question paragraphs on the reading are due. These comments/questions must be sent to firstname.lastname@example.org by 7 AM on the dates indicated.
