Since disjunctivists when talking about perception deny that hallucinations and veridical perceptions have a common fundamental nature, they need some other way to account for the fact that these kinds of experiences can ‘seem the same’ from the inside. A natural response is to give a purely epistemic account of hallucination, according to which there is nothing more to hallucinations than their indiscriminability from veridical perceptions. This chapter argues that the epistemic conception of hallucination falters in its treatment of cognitively unsophisticated creatures, and that it cannot respect all the facts about what we can know on the basis of introspection.
