 Finally, it should be reiterated that the notion of nonconceptual content is essentially contrastive—and the significance of the notion depends upon the particular way of understanding concepts with which it is contrasted. Some psychological states that would count as nonconceptual for a theorist with a rich and demanding notion of what it is to possess a concept would be conceptual for a theorist with a more relaxed view of concepts. Before we can plausibly claim to have a full understanding of the possibilities of the notion of nonconceptual content, we need to have a much clearer view than we currently have of what it is to possess a concept. As we saw earlier, on the most minimal view of concepts, a thinker can be credited with a concept of Fs provided that he can discriminate things that are F from things that are not F. A richer view of concepts might demand that the thinker have a full appreciation of the grounds on which one might judge something to be an F. The most demanding view of concepts might require the thinker to be able to justify and defend the judgment that something is an F. Clearly, different locations on this broad spectrum will generate different ways of thinking about what is to count as nonconceptual content—as well as different assessments of the overall significance of the notion.
