After his Habilitation, Brentano had started to work on a large scale work on the foundations of psychology, which he entitled Psychology from an Empirical Standpoint. The first volume was published in 1874, a second volume (The Classification of Mental Phenomena) followed in 1911, and fragments of the third volume (Sensory and Noetic Consciousness) were published posthumously by Oskar Kraus in 1928.
Shortly after the publication of the first volume, Brentano took a job as a full professor at the University of Vienna, where he continued a successful teaching career. During his tenure in Vienna, Brentano, who was very critical towards his own writing, no longer wrote books but turned instead to publishing various lectures. The topics range from aesthetics (Das Genie [The Genius], Das Schlechte als Gegenstand dichterischer Darstellung [Evil as Object of Poetic Representation]) and issues in historiography to The Origin of the Knowledge of Right and Wrong, in which Brentano laid out his views on ethics. The latter was Brentano’s first book to be translated into English in 1902.
In 1880, Brentano and Ida von Lieben decided to wed. They had to confront the fact that the laws of the Austro-Hungarian Empire at the time did not allow someone who had been ordained a priest to marry. Brentano, thus, gave up his Austrian citizenship, which meant that he also had to give up his position at the University of Vienna. He moved temporarily to Saxony, where he finally married. When he came back to Vienna a few months later, the Austrian authorities did not reassign him his position. Brentano became Privatdozent, a status that allowed him to go on teaching—but did not entitle him to receive a salary or to supervise theses. For several years he tried in vain to get his position back. In 1895, after the death of his wife, he left Austria disappointed; at this occasion, he published a series of three articles in the Viennese newspaper Die neue freie Presse entitled Meine letzen Wünsche für Österreich [My Last Wishes for Austria] (which soon afterwards appeared as a self-standing book), in which he outlines his philosophical position as well as his approach to psychology, but also harshly criticized the legal situation of former priests in Austria. In 1896 he settled down in Florence where he got married to Emilie Ruprecht in 1897.
Brentano has often been described as an extraordinarily charismatic teacher. Throughout his life he influenced a great number of students, many of who became important philosophers and psychologists in their own rights, such as Edmund Husserl, Alexius Meinong, Christian von Ehrenfels, Anton Marty, Carl Stumpf, Kasimir Twardowski, as well as Sigmund Freud. Many of his students became professors all over the Austro-Hungarian Empire, Marty and Ehrenfels in Prague, Meinong in Graz, and Twardowski in Lvov, and so spread Brentanianism over the whole Austro-Hungarian Empire. Another of Brentano’s students, Tomas Masaryk, was to become founder and first President (from 1918 to 1935) of the Republic of Czechoslovakia, where he created ideal conditions for the study of Brentano’s philosophy. These factors explain the central role of Brentano in the philosophical development in central Europe, especially in what was later called the Austrian Tradition in philosophy.
