Talk Title:  “Where Do You Get Your Protein? (Or: Biochemical Realization)”

Talk Abstract:  Biochemical kinds such as proteins pose interesting problems for philosophers of science. They can be studied both from the point of view of biology and chemistry, but these different perspectives may result in different classificatory practices. I will examine the tension that such classificatory differences produce. We will see that the reducibility of the biological functions of biochemical kinds to the chemical structures that realize these functions is a key question here. This leads us to a more general discussion of multiple realizability and realization at the biology-chemistry interface. The conclusion is that genuine multiple realizability may be rare at this interface.
