 Brentano regards time as a continuum of which only one point, the present moment, is real. As a consequence, mental phenomena do not have temporal extension (very much like like mathematical points on a line). The question, now, is: how can mental phenomena, which do not have any temporal extension, be directed towards objects that are extended in time? Can we be directed towards the melody, or only towards a (very small) temporal part of it? Brentano solves this problem by arguing that the object of a presentation does not vanish immediately from consciousness in the moment the presentation is over, it is rather retained in consciousness for a short while. In order to explain this process, he introduces the notion of “original association” or “proteraesthesis”, which, as de Warren suggests, “occupies a notable place in the list of Brentano’s conceptual innovations; in contrast to other distinguishing concepts of descriptive psychology ... it is without precedence in the history of philosophy” (De Warren 2009, 57f).
