Brentano’s Psychology And Logic And The Basis Of Twardowski’s Theory Of Presentations

Abstract

It is widely known that Kasimir Twardowski was a student of Franz Brentano. In view of the fact that Brentano generally had great impact through his lectures, especially during his Vienna period (1874-1895),and consequently became one of the towering figures of Austrian philosophy, it is a matter of no small interest to determine how he influenced Twardowski.  I’ll first consider presentations as they are described in Brentano’s psychology and then proceed to discuss Brentano’s account of the latter in his logic.
