 A third response to self-stultification begins with the observation that terms for sensory qualities (words for colors, flavors, pitches and timbres, etc.) must be learned. Very plausibly, this learning depends (a) on correlations between properties of present objects and production of words for those properties by surrounding adult speakers; and, consequently, (b) on correlations between brain event types that are caused by the properties of those objects, and brain event types that are caused by the hearing of adults’ words. It also plausibly depends (c) on the brain’s sensitivity to the correlation of brain events in (b). It is part of epiphenomenalist theory that the first brain events mentioned in (b) include causes of sensations of characteristic kinds, and that, after learning, those same brain events causally determine the production of predicates in sensation reports. The combination of these relations ensures that, so long as conditions in the brain are normal, a report of a sensation is guaranteed to correctly identify the kind of sensation that is normally caused in the speaker by objects that are standardly described by the predicate in the report. This guarantee underwrites a claim to knowledge of what kinds of sensation we are having.
