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. (shrink)

This paper seeks to define the main trends, arguments and problems regarding the question of method formulated by Twardowski and his students. In this regard, the aim of the paper is twofold. First, I situate Brentano’s project of descriptive psychology within the context of disputes in the school of Twardowski concerning the method of both psychology and phenomenology, arguing that descriptive-psychological analysis was dominant in this respect. Second, the study explores the notion of eidetic phenomenology, as founded on a methodological (...) procedure, which supposed to guarantee infallibility of its descriptions. To show this, I first reconstruct Brentano’s concept of descriptive psychology, its object, its method and aims. Second, I track the changes and reinterpretations provided by Twardowski in his view of descriptive-psychological analysis. Third, I explore Witwicki’s and Bandrowski’s—both early students of Twardowski—discussions of the descriptive approach. I try to show that the former accepted psychologism, while the latter overcame it by means of logical analysis. Fourth, I suggest that the only student of Twardowski who renounced the Brentanian method was Ingarden, who developed eidetic phenomenology. Finally, I present Blaustein’s—one of the last students of Twardowski—reappraisal of descriptive psychology and his critique of Ingarden’s method. This controversy over the method of descriptive psychology reveals how one can situate Twardowski’s legacy within early phenomenology in Poland. (shrink)
