 One of the more intriguing features of late medieval epistemology in general, and of Ockham’s view in particular, is the development of a theory known as “intuitive and abstractive cognition.” The theory is found in authors as diverse as Duns Scotus, Peter Auriol, Walter Chatton, and Ockham. But their theories of intuitive and abstractive cognition are so different that it is hard to see any one thing they are all supposed to be theories of. Nevertheless, to a first approximation, intuitive cognition can be thought of as perception, whereas abstractive cognition is closer to imagination or remembering. The fit is not exact, however, since authors who had a theory of intuitive and abstractive cognition usually also allowed the distinction at the intellectual level as well.
