Phenomenology is not specially concerned with phenomena in the sense of sense-data. Nor is it, unless per accidens any sort of Phenomenalism.

The title (which is a misleading one) derives from the following historical source. Brentano, following Herbart, repudiated the psychologies which treated mental faculties as the ultimate terms of psychological analysis, and insisted instead that the ultimate data of psychology are the particular manifestations of consciousness. These he called ‘psychic phenomena’, not as being appearances as opposed to noumena or things in themselves, but as being directly discernible manifestations of mental functioning as opposed to being inferred or constructed mental ‘powers’. So ‘Phenomenology’ only means, as it stands, the science of the manifestations of consciousness and might have been used-though it is not-as another name for psychology.
