    Challenges→Reid's direct theory of perception delivers knowledge of the external world.

    Direct realism entails that perception gives us unmediated access to objects, but perceptual illusions and hallucinations demonstrate that experience can systematically misrepresent the world.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Illusions and hallucinations involve the same neural processes as veridical perception, suggesting they're failures of the same direct access system.
      ?

      Think about whether this reason is strong or weak

    • 2.We must distinguish between perception itself (direct access) and the interpretation/judgment that may follow it (which can misrepresent).
      ?

      Think about whether this reason is strong or weak

    • 3.The fact that we *detect* misrepresentation presupposes some direct contact with reality against which to measure the error.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.If perception gives unmediated access, there should be no systematic gap between how things appear and how they are—yet illusions are universal.
      ?

      Think about whether this reason is strong or weak

    • 2.The same proximal stimulus can produce opposite perceptual experiences, showing access is mediated by interpretation, not direct.
      ?

      Think about whether this reason is strong or weak

    • 3.Direct realism cannot explain why hallucinations feel indistinguishable from perception without positing an intervening representational medium.

    Key Terms

    Direct Realism
    The view that we can directly perceive ordinary objects
    Hallucinations(the comparison case being analyzed)
    Experiences where you seem to see, hear, or feel something that isn't actually there—your mind creates the experience without real sensory input.
    Misrepresent(as used to describe how anthropocentric thinking gets nature wrong)
    To describe or portray something in a way that is inaccurate or gives a false impression of what it actually is.
    Perceptual illusions(as used in epistemology (the study of how we know things))
    Tricks your senses play on you where your eyes or ears report something that isn't actually true, even when you check the facts.
    Unmediated access(what direct realism claims perception provides)
    Getting direct contact with something without anything getting in the way or filtering what you experience; like touching something directly rather than through a thick glove.
    perception(Hume's theory of ideas)
    Any mental activity that brings something before the mind; the basic unit of mental life in Hume's theory of ideas.
