 If the generality constraint is taken to be an essential characteristic of conceptual thought (as it is by Evans 1982, Peacocke 1992, and Heck 2007, for example) then it seems to follow that many (if not all) non-linguistic creatures are not capable of engaging in conceptual thought. For illustration we can look again at infants’ object perception. Though the infant is capable of representing its environment in a particular way that explains its expectations regarding object motion and object persistence, the fact that such representations are domain-specific suggests that this characteristic of conceptual thought is violated. In particular, the domain-specificity of this type of cognition makes it the case that capacities operative in constructing object representations are not ones that can be engaged generally in contexts falling beyond the domain of operation of the module. Thus, we have a violation of the generality constraint with respect to these representations. This suggests that the kinds of capacities that are involved in the infant’s representation of the environment are not conceptual. So, if they are correctly described as representing the world at all, their representations must be nonconceptual. See also the discussion of analog magnitude representations in Beck (2012).
