The purpose of this paper is to theorize the author's teaching in a course for experienced university teachers, in a context of increased attention to such courses. The focus in the course is transforming and enhancing ways of being university teachers, through integrating knowing, acting and being. In other words, epistemology is not seen as an end in itself, but rather it is in the service of ontology. In the paper, the author explores and illustrates how this focus on ontology is enacted in the course.
