I can buy corollary discharge signals and central pattern generators as explanations for behavior in lower animals like pleurobranchia, but I still cannot help but find it overly simplistic for humans and for higher animals. I am anxious to begin discussing the I-function in terms of neural construction and functioning, because so far it is a very nebulous concept that definitely needs better definition. And I still haven't dropped the idea of consciousness, mostly because it is such a salient aspect of experience (not that introspection is a great way of substantiating theories), but also because it does have incredible adaptive/evolutionary possibilities in terms of expanding behavioral possibilties beyond those which are afforded by innate neural connections.

Don't too quickly equate what we've been talking about with "innate" neural connections. Remember CPG's can be acquired from experience (and presumably CD's as well). Furthermore, there's a lot "innate" about the "I-function", and "consciousness" (which no, you shouldn't give up). And don't presume we haven't yet been exploring things relevant to understanding the latter two concepts. Its important to know what can be done without an "I-function", both because it helps to define what might be special about it and, it will turn out, because you can't have an "I-function" without the things we've been (and will be for a while) talking about.
