An analysis of conceptual ambiguities in the debate on the format of concepts

Abstract There is a debate in philosophy and cognitive science over whether concepts – the building blocks of thought—are couched in a perceptual modality or are amodally represented. The empirical evidence so far collected seems not to have adjudicated this question yet, as reinterpretation of the same set of evidence by both supporters of modalism and amodalism have been provided. I offer a critique of such reinterpretations, arguing that they ultimately derive from theoretical problems in the definition of a modal representation. In particular, I will review three criteria which have been offered to distinguish amodal concepts from modal ones: the isomorphism criterion, the neural location criterion, and the input specificity criterion. I will explain how these criteria often lack theoretical clarity, making it possible in most cases to propose a parsimonious explanation of the same set of data from both an amodalist and a modalist perspective. As a result, it becomes impossible to empirically discriminate between the two interpretations. My conclusion is that the main problem with the discussed criteria is that they frame the question on the format of concept as an either/or debate, by overlooking more interesting empirical questions.
