Mechanisms and Reduction in Organic Chemistry

Conference paper
Part of the European Studies in Philosophy of Science book series (ESPS, volume 5)

Abstract

Organic chemistry has a century-long tradition of thinking about mechanisms, yet chemistry is a striking omission from recent philosophical literature. In this paper I argue that current philosophical accounts of mechanism are too abstract, missing what’s important about mechanisms in chemistry. Given that they have been informed by studies of the biological and cognitive sciences, they also have a tendency to make general claims about mechanisms that fail for a physical science such as chemistry. I then critically examine arguments that successful mechanistic explanations effect reductions of special-science relationships. I argue that they need not. Mechanistic explanations illuminate by identifying lower-level realisers for higher-level entities or properties and (sometimes) applying the general laws that govern them to yield new information about those mechanisms. None of this assumes that the lower-level realisers causally exclude the things they realise, which is what the argument for reduction requires. Exclusion may be a widely shared assumption in metaphysics and the philosophy of mind, but it finds no support in the mechanistic explanations provided by organic chemistry. I argue that it has no place in naturalistic discussion of mechanism in the philosophy of science.
