 Now it might be argued that the Common Kind Claim applied to veridical perceptions and hallucinations is not as plausible as it is when applied to veridical perceptions and illusions. For veridical and illusory experiences are more naturally grouped together anyway, unlike veridical perceptions and hallucinations. For, at least before we encounter the argument from illusion, veridical perceptions and illusions are both naturally thought of as direct presentations of ordinary objects (it’s just that in illusory cases the presented objects appear other than they are). However, as noted above, from a phenomenological point of view, hallucinations too seem as though they are direct presentations of ordinary objects: from the subject’s perspective a hallucination as of an F cannot be distinguished from a veridical experience of an F. This is why it seems so plausible to think of them as fundamentally the same.
