Brentano's Classification of Mental Phenomena

In Chapter 3 of Book I of Psychology from an Empirical Standpoint, Brentano articulates what he takes to be the four most basic and central tasks of psychology. One of them is to discover the ‘fundamental classification’ of mental phenomena. Brentano attends to this task in Chapters 5-9 of Book II of the Psychology, reprinted (with appendices) in 1911 as a standalone book (Brentano 1911a). The classification is further developed in an essay entitled “A Survey of So-Called Sensory and Noetic Objects of Inner Perception,” published posthumously in Brentano 1928/1981b, as well as a 1907 dictation entitled “Loving and Hating,” reprinted in Brentano 1969.
