 The notion of nonconceptual content is fundamentally contrastive. In elucidating it we need to start with the notion of conceptual content. The paradigm case of a state with conceptual content is a propositional attitude such as a belief or desire. Having a propositional attitude involves standing in a certain relation to a content (a thought or a proposition). The content is what it is that is believed, desired, hoped for etc. Although propositional attitudes are ultimately directed at certain objects, properties and/or relations (which yield their truth-condition, and in terms of which their truth-value is to be determined), it is clear that only certain ways of characterizing those objects/properties/relations can serve to specify the content of the relevant propositional attitude. It would be incorrect, for example, to characterize the content of my current belief that my car is parked in the driveway by using the concepts of particle physics to describe the state of affairs that would make it true. This would be incorrect because it completely fails to capture how I think about the state of affairs of my car being in the driveway. The obvious question to ask, once this preliminary point is in play, is ‘What constraints are imposed upon specifications of the content of propositional attitudes by the requirement to respect the way the subject thinks about the truth-condition of the relevant attitude?’
