The father of modern philosophy.
Really, the opposition to natural selection by so many orthodox linguists is a scandal. The latest example is in Biolinguistics (here) in which the authors seek to refute Derick Bickerton's paper (PDF here), which I discussed in Biology Without Darwin? Bickerton's point was that even if a process is self-organizing rather than genetic, it becomes fixed in the species only through selection.
I have often thought that if I could just get a grip on the reason Chomskyans have such a distaste for natural selection, I would have a much clearer grasp of what at lies at the root of our disagreement. Chomsky is making an assumption; I hold a counter-assumption. They are so basic that I can stare them in the face and not see their radicalism. So I was relieved to find a paper by Francesco Ferretti and Ines Adornetti titled "Against Linguistic Cartesianism" (abstract here) that at last made the obvious pop out at me.
