 The core TT assumption that FP is a kind of theory leaves open whether our everyday ToM is a set of conceptually articulated, propositional representations that detail the core FP laws or whether it takes the form of a more flexible dynamic modeling of worldly structures. Several TTists, inspired by Giere (1988), maintain that our FP abilities are best explained by the tacit or unconscious processes of building and utilizing models at the subpersonal level rather than by appeal to the use of an inherited and fixed set of FP laws (Maibom 2003, 2007, 2009; Godfrey-Smith 2005).
