I studied philosophy at the universities of Salzburg, Munich and Tsukuba (Japan) and earned my PhD at Salzburg university in 1981 with a thesis about The transcendental theory of subject and cognition in twentieth century philosophy. After that I entered a professional career as a librarian in Linz. Now, since several years, returning to my roots, i'm pursuing intensively my interests in the fields of the theories of conciousness, cognition, and science, and in ontology.
