In his attempt to account for knowledge, Kant argues that there are two 'strains' of knowledge, intuition and thought. While the former will permit of a priori knowledge in geometry and, possibly, mathematics, an interplay of intuition and concept will provide the a priori framework for experience. This interplay is twofold: since intuition is tied to receptivity, thought has access to intuited objects; the empirical non-emptiness of the a priori framework is guaranteed through sensibility. Intuition also offers a pure ordering of loci, and thus allows for an interplay of pure intuition and concept such that certain a priori constructs, categorized intuitables, can be claimed.
