Evolutionary Logic

Article by William Dembski:

Since the neo-Darwinian synthesis of the 1930s, evolutionary biology has become a growth industry. This growth has resulted in the demand for more flexible methods of establishing evolutionary biology's grandiose claims than the laborious, difficult, pedantic, and "rigorous" methods favored throughout the rest of the sciences. This demand has been met by what is now a well-developed branch of evolutionary biology known as evolutionary logic.

I can't here develop the theory of evolutionary logic in detail, but I will introduce some necessary terminology. In ordinary logic, which is used throughout the rest of the sciences, one is justified asserting that a claim is true provided one can formulate a coherent and rigorous argument that supports it. In evolutionary logic we relax both these restrictions: an evolutionary claim is true provided there is an evolutionary argument that supports it. This definition is sufficiently clear as not to require elaboration. Further, we stipulate that any circularity in this definition is virtuous rather than vicious.

The benefits and practical applications of evolutionary logic will be obvious. Professional authors of evolutionary tracts depend on it for their livelihood. Instructors in evolutionary biology find that evolutionary logic enables them to make complex ideas readily accessible to students regardless of their preparation or background (indeed, proficiency in evolutionary logic has been shown to be positively correlated with high self-esteem). Research workers in a hurry to claim priority for a new result or who lack the time and inclination to be pedantic find evolutionary logic useful for expeditiously writing up their results. In this respect evolutionary logic has a further advantage, namely, the results are not required to be true, thus eliminating a tiresome (and now superfluous) restriction on the growth of evolutionary knowledge...Continue Reading
