Franz Brentano (1838-1917) is a key figure in the development of Twentieth Century thought. It was his work that set Husserl on to the road of phenomenology and intentionality that inspired Meinong's theory of the object which influenced Bertrand Russell and the entire Polish school of philosophy. ^Descriptive Psychology presents a series of lectures given by Brentano in 1887; they were the culmination of his work and the clearest statement of his mature thought. It was this later period which proved to be so important in the work of his student Husserl. This is the first English translation of his work. Benito Muller has added a concise introduction which places Brentano within the history of philosophy and psychology and locates his influence in contemporary thought. Language: English
