 For some, the most important feature of modules, which separates them from other humdrum psychological mechanisms, is that they are assumed to be cognitive through and through. Fodor (1983), for example, maintains that the knowledge base of ToM modules is conceptually based and has the structure and content of a set of semantically connected propositionally articulated principles. In line with this view, Fodor (1994, 1998) proposes that the core mentalistic concepts get their meaning denotationally by means of special mechanisms that “lock on” to the relevant extensions. These concepts each play distinctive roles in constituting the principles that make up the network of laws comprising our folk theory of mind.
