 Results Continuity requires that the substantive claims of philosophical theories be supported or justified by the results of the sciences. For example, epistemologists like Goldman look to the results of psychology and cognitive science to find out how the human cognitive apparatus really works; only with that information in hand can the epistemologist construct norms for how humans ought to form beliefs (Goldman 1978, 1986). Similarly, moral philosophers like Allan Gibbard and Peter Railton, despite profound substantive disagreements, both think that a satisfactory account of morality’s nature and function must be supported by the results of evolutionary biology, our best going theory for how we got to be the way we are (Gibbard 1990; Railton 1986). A philosophical account of morality that explains its nature and function in ways that would be impossible according to evolutionary theory would not, by naturalistic scruples, be an acceptable philosophical theory.
