At this point those who would resist our argument might turn away from attacks that spring from physics, and claim instead that we are attacking a ``straw man:" They might say: ``Look, there are plenty of AI and Cog Sci researchers who don't affirm anything like Propositions 1 and 1'. In fact, one can be a darn good AI researcher and not take a stand on the relation between computation and cognition."
This objection is of course easily cast
aside -- because it fails to take account of the target we have set for ourselves.
We are not targeting a brand of AI concerned (say) exclusively with
engineering a computational
correlate to the olfactory component of rat brains.
We are
concerned with what, following tradition, we've called ``Strong" AI and
Cog Sci: a discipline which aims at replicating human cognition in part by
identifying, scientifically, cognition with computation.
Propositions 1 and 1' simply reflect our focus on this brand of AI/Cog Sci.
