These (also called investigations in descriptive psychology or psychognosy) were developed in lecture notes and other manuscripts which have only been partially published. There were in fact four psychology courses in which he attempted to initiate his students in phenomenological investigations. 3 The manuscripts that Brentano used for these courses are for the 1 For analyses of the relation between Brentano and Husserl, see Rollinger 1999 and Rollinger 2004.
