I studied philosophy at the Universities of Sydney (B.A. 1962, M.A. 1965) and Oxford (B.Phil. 1967).
I taught at the Australian National University (1967-1997).
From 1998 to 2007 I was Dean of Arts, first at ANU then at Southern Cross University.
Since 2007 I have been an adjunct professor in the SCHOOL OF PHILOSOPHICAL AND HISTORICAL INQUIRY at the University of Sydney.
From 2013 to 2015 I was a chercheur en rattachment principal at the LABORATOIRE SPHERE, University of Paris - Diderot.
My research is in two main fields:
