Disjunctivism is a position in the philosophy of perception that rejects the existence of sense data in certain cases.
"[2] Veridical perceptions and hallucinations are not members of a common class of mental states or events.
[3] Disjunctivism was first introduced to the contemporary literature by Michael Hinton, and has been most prominently associated with John McDowell.
[1] Other prominent disjunctivists include Bill Brewer,[6] Mike Martin, John Campbell[7] and Naomi Eilan.
[9] Disjunctivists often hold that an important virtue of their view is that it captures the common sense idea that perception involves a relation to objects in the world.
