bq. Introspection admits of several varieties, depending on which types of mental events are introspected. I distinguish three kinds of introspection (primary, secondary, and tertiary) and three explanations of the general capacity: the inside access view, the outside access view, and the hybrid view. Drawing on recent evidence from clinical and developmental psychology, I argue that the inside view offers the most promising account of primary and secondary introspection.
