Okay, now erm, today as you realize with feelings of immense relief is the last lecture of the term, so, so what I'm gonna do, is to start talking about the er, so called black books of Freud, the set texts in this, in this course and I'm gonna start talking today about the first, and in some ways, one of the most important of these, Totem and Taboo, and since it's the last lecture of term, and you probably all forget what I said over the Christmas holiday, and won't be able to recall it afterwards, through the alcoholic haze, er what I thought I'd do today, was talk about Totem and Taboo in the way in which it looked backwards rather than forwards.
