Four Ways from Universal to Particular: How Chomsky's Language-Acquisition Faculty Is Not Selectionist

Abstract

Following the development of the theory of the immune system, there was an attempt to characterize many biological mechanisms as being selectionist as juxtaposed to instructionist. But this broad definition would group Darwinian evolution, the immune system, embryonic development, and Chomsky's language-acquisition mechanism as all being selectionist. Yet Chomsky's mechanism (and embryonic development) are significantly different from the mechanisms of biological evolution or the immune system. Surprisingly, there is a very abstract way using two dual mathematical logics to make the distinction between genuinely mechanisms and what are better called generative mechanisms. This note outlines that distinction.
