 Before moving to other arguments that have been advanced on behalf of nonconceptualism it is worth remarking that the conceptualist appeal to demonstrative concepts in response to the fineness of grain argument is a response to a challenge to their position, rather than an argument for conceptualism. The point of the fineness of grain argument is to put pressure on the possibility of a subject possessing all the concepts required for a correct specification of the contents of perception. If the subject cannot have these concepts and yet is capable of undergoing the perception, then it follows that the content of perception is nonconceptual. However, showing that the subject does have these concepts is not yet an argument for the conceptualist position. For the conceptualist claim to follow, they must show not that the content of perception is in fact conceptualizable by the subject undergoing the experience in all of its fine grain, as the availability of demonstrative concepts suggests, but rather that the subject cannot undergo the experience without possessing these concepts. Thus even if the conceptualists manage to show that subjects do possess all the concepts involved in the correct specification of the content of perception, it still does not show that the content of perception is conceptual, it only undercuts the motivation the nonconceptualist can obtain from the fineness of grain argument (Coliva 2003, Bermúdez 2007).
