Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? In this chapter we apply this argument to beliefs in three different domains: morality, religion, and science. We identify replies to evolutionary scepticism that work in some domains but not in others. The simplest reply to evolutionary scepticism is that the truth of beliefs (...) in a certain domain is, in fact, connected to evolutionary success, so that evolution can be expected to design systems that produce true beliefs in that domain. We call a connection between truth and evolutionary success a ‘Milvian bridge’, after the tradition which ascribes the triumph of Christianity at the battle of the Milvian bridge to the truth of Christianity. We argue that a Milvian bridge can be constructed for commonsense beliefs, and extended to scientific beliefs, but not to moral and religious beliefs. An alternative reply to evolutionary scepticism, which has been used defend moral beliefs, is to argue that their truth does not depend on their tracking some external state of affairs. We ask if this reply could be used to defend religious beliefs. (shrink)

Evolutionary psychologists, among others, have used a method called “reverse engineering” to uncover ( a ) whether a trait was selected for, and ( b ) if so, why that trait was selected for. In this paper I argue that reverse engineering cannot deliver on either ( a ) or ( b ), and tends to pervert, rather than enhance, our knowledge of natural history. In particular, I expose as false a fundamental assumption of reverse engineering—namely, that all traits selected (...) for a particular function will share some nontrivial properties. *Received March 2006; revised June 2008. †To contact the author, please write to: Department of Philosophy, 229 Major Williams Hall (0126), Virginia Tech, Blacksburg, VA 24061; e‐mail: haufe@vt.edu.
