T. Ryan GregoryLike many of the early works that have had a lasting impact on biological thought, Paley’s Natural Theology remains worthy of reading by the current generation of biologists, educators, and students. It presents the argument from design in a clear fashion, unencumbered by the mathematical and biochemical accoutrements with which it recently has been festooned. That arguments very similar to Paley’s are now being used in an attempt to undermine the teaching and acceptance of evolutionary science gives Natural Theology continued relevance. From a much more positive point of view, his wonder at the complexity of the natural world, expressed with sincerity and style, is something to which all evolutionary biologists can relate. It is to be hoped that, in time, it will be for this reason alone that Paley’s classic treatise retains its significance.
