The point is that the Empiricist must account for the repertoire of representation types that figure in the processing and for the machinery that does the processing.  The ultimate outcome of this debate will depend in part on how distinctive and complex the computational machinery turns out to be.  If the engine for theory of mind dynamics only needs to do tree search or production rule application (for example), then the case for Empiricism is strengthened, because these are very general computational capacities. Only the content of the specific rules or the content at the nodes will be domain-specific.  But the more idiosyncratic the computational machinery in a specific subsystem—for example, a simulator that anticipated motions and locations in a dynamic physical scene—the greater the challenge for the Empiricist to explain how such an internal computational device is acquired from experience alone.
