Ideas of David M. Rosenthal, by Text

[American, fl. 1994, Professor at the Graduate Center, City University, New York.]

1998 Instrospection
p. Introspection is not perception, because there are no extra qualities apart from the mental events themselves
     Full Idea: Introspection cannot be a form of perceiving, since that invariably involves sensory qualities, and no qualities occur in introspection other than those of the sensations and perceptions we introspect; there are no additional qualities.
     From: David M. Rosenthal (Instrospection [1998])
     A reaction: This sounds pretty conclusive. Presumably introspection is best described as meta-thought rather than perception, which means that it involves beliefs and judgements, rather than new perceptual qualities. It has to be conceptual, and probably linguistic.
