Philosophy of Biology Fall 2011, Tues., Thurs., 12:30-1:50 pm

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.
