Lucy Allais’s Manifest Reality presents a systematic discussion of the role that Kant assigns to concepts in making knowledge of objects possible. In this paper, I ascribe to Allais a version of non-conceptualism, according to which knowledge is a ‘hybrid’ or loose unity of concept and intuition; concept relates to intuition as form relates to matter in an artefact. I will show how this view has trouble accommodating the distinction between knowledge and accidentally true belief, and how it leads to objectionable forms of idealism.
