[quoting Tripp, 22 Oct 96.c] The answer is that the knowledge is hard-wired into your brain. It could not possibly be constructed (by a five-year old child?) and besides; why would all of us construct the same idea? The rules of Universal Grammar apply to all languages so they could not possibly be a cultural construction. Pinker argues by extension that the basic "rules" of all kinds of human activity are hardwired. So much for constructivism.
Does that mean our ID programs should really be focusing on brain surgery and electronic circuit repair and design? I can see it now, "Preparation of Inexpensive Materials" is replaced by wire cutting and soldering.
