Arguing Darwin

An exacting essay by Michael Ruse on the general ignorance of science among anti-Darwinists:

But rather than work over the details, I want to draw attention to the way this crop of critics ignores evolutionary biology—aside from the kind of cherry-picking in which Fodor engages. Nagel may sneer about the failure to find “accessible literature” that answers his worries. In what part of the library was he doing his literature search? Where, for example, is any discussion of the Grants’ work on the Galápagos finches? What about a detailed look at the new scholarship that is challenging earlier thinking about the evolution of bipedalism? What about the discoveries of molecular biology and of the similarities (homologies) between humans and fruit flies? And why no mention of Marc Hauser and his work uncovering the secrets of moral thinking? There is a deafening silence on those and other issues. Fodor, Nagel, and Plantinga don’t need to turn themselves into biochemists, but some awareness of the issues and advances would not be entirely misplaced.

This total lack of interest in the science is surely suggestive. The critics are being driven by other, for them deeper, concerns. And as an evolutionist, I turn to the past for clues. What fueled the initial opposition to Darwin was a concern with our species, with Homo sapiens. For 150 years, since the Origin, critics have feared that we humans might become part of the evolutionary picture—not just our bodies, but our minds, our very souls. What makes us distinctively and uniquely human? This worry is still alive and well in today’s philosophical community. Plantinga is open in his fear that Darwinism makes impossible the guaranteed existence of our species. More, for years he has argued that Darwinism is bound up with the metaphysical belief that everything is natural (as opposed to supernatural), and that this leads to a collapse of rational belief and knowledge. The chance elements in Darwinism are simply not compatible with Plantinga’s Christian faith.

If you are going to be a philosopher or ethicist commenting on scientific issues you must be reading the literature of science. One can’t critique Darwin if one doesn’t understand how the eye evolved. Philosophy needs to get over its fear of empirical data.
