McDowell recently renounced the assumption that the content of any knowledgeable, perceptual judgement must be included in the content of the knowledge grounding experience. We argue that McDowell’s introduction of a new category of non-inferential, perceptual knowledge is incompatible with the main line of argument in favour of conceptualism as presented in Mind and World [McDowell, John. 1996. Mind and World. 2nd ed. Cambridge, MA: Harvard University Press]. We reconstruct the original line of argument and show that it rests on (...) the assumption that a specific model of justification, the Comparison Model, must apply to all cases of non-inferential, perceptual knowledge. We then show that the Comparison Model cannot be applied to McDowell’s new category of non-inferential, perceptual knowledge. As a consequence, McDowell is in need of an alternative model of justification and an alternative argument for conceptualism. We propose such an alternative model of justification based on McDowell’s reading of Sellars, but argue that the model only serves to make the need for an alternative motivation for conceptualism more urgent.

John McDowell articulated a radical criticism of normative inferentialism against Robert Brandom’s expressivist account of conceptual contents. One of his main concerns consists in vindicating a notion of intentionality that could not be reduced to the deontic relations that are established by discursive practitioners. Noticeably, large part of this discussion is focused on empirical knowledge and observational judgments. McDowell argues that there is no role for inference in the application of observational concepts, except the paradoxical one of justifying the content (...) of an observational judgment in terms of itself. This paper examines the semantical consequences of the analysis of the content of empirical judgments in terms of their inferential role. These, it is suggested, are distinct from the epistemological paradoxes that McDowell charges the inferentialist approach with. (shrink)
