Back to required reading

One strain of the recent work on ethics and evolution stems from E.O. Wilson and Sociobiology. His views were briefly described in his two books and then there was a series of papers of his, Michael Ruse, and the two of them working together arguing that there is a connection between the two. Only one such paper is listed here followed by a response to the literature by Philip Kitcher.

The Ruse piece that we read is part of Contemporary Debates in Philosophy of Biology. Ruse's companion piece is by Francisco Ayala.

A clear paper which argues for ethical skepticism on an evolutionary basis is by Richard Joyce. He has two books on the subject: The Myth of Morality and The Evolution of Morality. Actually, he argues for error theory -we think that there are moral predicates and we talk as though moral claims are true or false (not emotivist or subjectivist) but that in fact, there are no moral predicates.
