    HistoryEditSee Inverse

    In cases of illusion, there must be something experienced that has the features the perceiver takes themselves to be experiencing, and these experiential objects are called sense-data.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.There are cases of illusion in which a perceiver has a sensory experience as of seeing something with specific features, but nothing in the environment has those specific features.
      ?

      Think about whether this reason is strong or weak

    • 2.In those cases of illusion, something must be experienced that accounts for the apparent features.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.In illusion cases, the perceiver misrepresents an actual physical object—the stick in water is still experienced, just distorted.
      ?

      Think about whether this reason is strong or weak

    • 2.A misrepresentation of a real object requires no intermediary sense-datum; the intentional content of the experience can simply be false.
      ?

      Think about whether this reason is strong or weak

    • 3.Positing sense-data to explain misrepresentation generates a regress: we would need further intermediaries to explain how sense-data themselves are perceived.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.The inference from 'x appears F' to 'there is an object that is F' commits the sense-datum fallacy identified by Chisholm and later Austin himself.
      ?

      Think about whether this reason is strong or weak

    • 2.Adverbial theorists like Roderick Chisholm and George Pitcher show 'experiencing redly' describes a mode of perceiving, not a red object experienced.
      ?

      Think about whether this reason is strong or weak

    A person or being that experiences something through their senses, like hearing a sound or seeing a color.
    illusion(Austin's taxonomy of perceptual error)

    Central to those considerations are those organized by versions of what is known as the argument from illusion ((6) above).[21] The version of the argument that Austin criticizes can be reconstructed as follows. (i) There are cases of illusion in which we have a sensory experience as of seeing something of some sort with specific features but in which nothing has those specific features. This might be because, although we experience something of the sort in question, the thing we experience la
