Ruse's Darwin and Design: Does It Go Far Enough?

Abstract

Michael Ruse's forthcoming book gives an enjoyable history of teleology in biology, philosophy, and theology. It argues that concepts of cause, final cause, purpose, teleology, function, design, adaptation, contrivance, progress, ends, and value have all been telescoped by most writers in those three disciplines but that these concepts (and especially the concept of design) are nonetheless valid, provided only that we recognize their metaphorical nature. I agree with this basic argument, and Ruse's critiques and historical summaries of these concepts are both useful and delightful. However, I also explore one major and three minor reservations. The minor reservations are that Ruse overdoes the allegation of telescoping, does not adequately explore ways to express teleology more accurately, and erroneously denies the existence of biology–based theologians who make the same point he is making. The major reservation is that, despite all the groundwork he lays, Ruse comes to a conclusion other than the one clearly suggested by his first fourteen chapters. If he followed the evolutionary story just a bit further, to include the evolution of the human brain, he would be in a position to articulate a theologically sophisticated understanding of teleology and avoid an ending that is uncharacteristically tame.
