Deviant causal chains and the irreducibility of teleological explanation

We typically explain human action teleologically, by citing the action's goal or purpose. However, a broad class of naturalistic projects within the philosophy of mind presuppose that teleological explanation is reducible to causal explanation. In this paper I argue that two recently suggested strategies - one suggested by Al Mele and the other proposed by John Bishop and Christopher Peacocke - fail to provide a successful causal analysis of teleological explanation. The persistent troubles encountered by the reductive project suggest that teleological explanations are irreducible and that the naturalistic accounts of mind and agency should be called into question.
