According to Robert A. Larmer, theistic evolutionists locate appeals to divine design outside scientific practice. By contrast, those in the intelligent design movement attempt to integrate the concept of design into scientific practice. This article suggests that there are reasons for thinking that theistic evolutionism represents an untenable halfway house between a philosophically robust theism and a thoroughgoing naturalism; in addition, although it is a work in progress that faces a number of challenges, the intelligent design movement provides a promising model for the integration of scientific and theological belief. Mr. Larmer is Professor of Philosophy at the University of New Brunswick and past President of the Canadian Society of Christian Philosophers.
