If teleological descriptions and explanations are to have a legitimate place in contemporary empirical science, especially as regards biological units in general and even nonbiological ones, then their content must avoid appeal to intentional constituents. Efforts aimed atreducing teleological accounts to nonteleological ones (Braithwaite, Nagel, etc.) have proved unsuccessful (Scheffler). Recently, Larry Wright, building on the work of Charles Taylor, has put together a nonreductive analysis which is free from many of the objections often associated with such a program. I (...) maintain that while Wright and Taylor are on the right track, serious problems still remain for their theories. An analysis is suggested which avoids these difficulties. (shrink)
