@fresco,
Demise? Have you not seen the National Academies of Sciences or Sugeon General's reports on behavior analysis? Are you that unaware of the rise in certified and licensed practioners?
And Chomsky...as a quick note, that was 1959 that his review of Skinner's book was published. The more important point is that Chomsky, himself, dropped his theory on generative grammar. Linguists moved onto other theories, but Skinner's carried on and to this day has informed peer-reviewed research that has helped thousands of people with speech and language challenges.
Regarding philosophy and science, I much prefer looking to science for explanations of natural phenomena and translational work for usable practices.
