    Cases of illusion and cases of delusion/hallucination are of the same basic type and warrant the same type of explanation

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.In the illusion case, the erroneous perceptual judgment is explained by appeal to sense-data rather than a directly experienced environmental feature
      ?

      Think about whether this reason is strong or weak

    • 2.Once illusion is explained via sense-data, the illusion case cannot be distinguished from the delusion case by appealing to the presence of an environmental feature in the former and its absence in the latter
      ?

      Think about whether this reason is strong or weak

    • 3.When two cases cannot be distinguished by the most salient candidate distinguishing feature, it is natural to treat them as the same basic type
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Illusions require the presence of a real object causally responsible for the experience, while hallucinations involve no such external causal anchor.
      ?

      Think about whether this reason is strong or weak

    • 2.This causal-object distinction grounds fundamentally different etiological explanations: one involves misrepresentation of something present, the other involves representation of something absent.
      ?

      Think about whether this reason is strong or weak

    • 3.Cases with structurally different causal histories belong to different explanatory types, regardless of phenomenological similarity at the level of sense-data.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Grice's causal theory and disjunctivist accounts (McDowell, Hinton) jointly show that the move from phenomenal indistinguishability to same-type explanation is a non-sequitur.
      ?

      Think about whether this reason is strong or weak

    • 2.Two events can be phenomenally identical yet differ in their constitutive conditions, as the veridical and hallucinatory cases differ in what metaphysically constitutes them.
      ?

      Think about whether this reason is strong or weak

    • 3.Ayer and Ayer-style sense-datum theorists beg the question by presupposing that shared phenomenology entails shared ontological and explanatory category.

    The distinction between sensory perception and judgmental acumen enables Austin to distinguish between central cases of illusion and central cases of delusion, and also to sketch explanations of what is going on in those cases that do not make appeal to sense-data. Austin takes the defender of (i) and (ii) to argue as follows. First, consider an illusion, for example a stick that looks bent but really isn’t. Such an illusion has two key features. First, it clearly involves a distinctive sensory
