On this episode of ID the Future historian Michael Flannery continues discussion of his new bookNature’s Prophet: Alfred Russel Wallace and His Evolution from Natural Selection to Natural Theology. Flannery tells how Wallace became convinced of some “overruling intelligence” in nature — not because of “gaps” in what he knew, but because so many human attributes demand a better explanation than Darwin’s own “utility principle.” They called for a cause adequate to the effects.
