The Mechanist and the Snail

Abstract

[Introduction] One of the most influential theories of scientific explanation to have emerged in the past two decades is Salmon's causal/mechanical theory (Salmon 1984). According to this account, scientific explanations describe a network of causal processes and interactions. In this paper, I will use an example from evolutionary biology to argue that the causal nexus, as characterized by Salmon, is not rich enough to account for many causal explanations in the sciences.
