Heterophenomenology is not an intuition pump, but another example of staging that is well worth putting in place before we tackle some difficult questions. Heterophenomenology is the study of first-person phenomena from the third-person point of view of objective science. The core of heterophenomenology: it exploits our capacity to perform and interpret speech acts, yielding a catalogue of what the subject believes to be true about his or her conscious experience. This catalogue of beliefs fleshes out the subject’s heterophenomenological world, the world according to S, the subjective world of one subject. The total set of details of heterophenomenology, plus all the data we can gather about concurrent events in the brains of subjects and in the surrounding environment, comprise the total data set a theory of human consciousness must explain. It leaves out no objective phenomena and no subjective phenomena of consciousness.
