'I’ve been asked to talk on my thesis, ‘The Broken Years’, which I wrote at the ANU in 1967–70, and particularly to mention aspects which might help you. You know the basic rules, so I’ll talk about what to say. Every topic and set of sources has its own challenges and opportunities, but I urge you from the beginning to think constantly about what you want to say, and to ensure that what you say rises from and above your sources to comment on the human condition. Your thesis only begins as a sequence of well researched and arranged sources. No less than literature, art and music, it should end by having significance arching above your topic.' (Introduction)
