The faculty psychology of Thomas Reid

Contradictory versions of Reid's faculty psychology have been presented. A reexamination of Reid's writings suggests that the term, faculty, was used not as a classificatory device but rather to refer to innate, universal, and active mental powers. Being active, the faculties are one of the basic causes of observable psychological phenomena. The relation of the faculties to other mental powers is considered. A new listing and classification of such powers is compared with that presented in 1936 by H. D. Spoerl which has been used as the basis for much of the subsequent analysis of Reid's faculty psychology.
