ABSTRACT
The representations that were considered in the last chapter constitute objects not only for humans but for animals, and they come solely under the faculties of sensibility and understanding.1 The representations to be considered now, by contrast, are proper to humans, and come under the faculty of reason; in other words, reason is the faculty of representations of representations, the faculty of concepts. It is important not to confuse concepts with the categories, the operations of the understanding, whose task it is to unite space and time and render them apprehensible. It is particularly important not to confuse them, though this is often done, with the category of unity which unites the manifold of sensuous intuitions.
