 Wodeham’s decision to identify the difference between intuitive and abstractive knowledge with the presence or absence of an object, as Scotus and Ockham did, meant that he shared with these two thinkers a common opponent, namely Peter Aureoli. In response to Scotus’s definition of intuitive knowledge Aureoli identified several experiences wherein a person appears to have a sensitive intuition of a non-present object. Such experiences, according to Aureoli, were the consequence of lingering sensitive images that remain even after an object is no longer present. Such lingering images (sometimes called esse perspectivum or esse apparens) were used to explain all sorts of visual anomalies that do not correspond to reality. Such experiences were enough for Aureoli to define intuitive knowledge, not as the direct grasp of a present object, but as direct knowledge (as opposed to knowledge arrived at through a discursive reasoning process).
