Ludwig Wittgenstein taught only a couple of Australian philosophers, at Cambridge in the late 1940s, and one of them, Frank "Camo" Jackson (Chair, Philosophy, Monash University) taught the author epistemology and philosophical psychology in the 1970s. In this article, the author describes how this teaching was central to his subsequent work in academia, which itself didn't get under way until a decade of primary and secondary school teaching. That school teaching showed him how practice(s) shape identities, and how policies are shaped by practices.
