Abstract
Ever since what may be called Descartes’ ‘epistemological turn’ in the treatment of philosophic questions, philosophers who have concerned themselves with the problem of truth have had, as well, the added concern of avoiding the tendency whereby epistemology is reduced to ‘mere psychology’, or else they have themselves fallen prey to that tendency. Brentano thought he had avoided this danger in his major work, Psychologie vom empirischen Standpunkt. The title itself suggests that he may not have been altogether successful in skirting some psycho-logistic entanglement.
