Introduction to Ancient Greek History (CLCV 205)Uploaded 20-11-08In this lecture, Professor Kagan describes the aftermath of the Thirty Years Peace. He argues that the Peace had the potential to keep peace between Athens and Sparta due to the arbitration clause. In addition, he argues that during this time, Athens sends various diplomatic messages to the wider Greek world stating their intentions for peace, such as the Panhellenic venture to establish Thurii. However, this peace is seriously challenged when Corinth and Corcyra come into conflict over Epidamnus. At this point, Athens could make an alliance with Corcyra and run the risk of angering Sparta or allow Corinth to potentially take over Corcyra's navy and change the naval balance of power. Athens decides on a defensive alliance.00:00 - Chapter 1. Preserving the Thirty Years Peace10:12 - Chapter 2. The Pan-hellenic Colony of Thurii22:05 - Chapter 3. Testing the Peace38:30 - Chapter 4.

The American Novel Since 1945 (ENGL 291)Uploaded 21-11-08In this final lecture on The Human Stain, Professor Hungerford argues that desire is the engine of narrative, for Roth, both at the structural level and in the very grammar of his sentences. Sex and writing are alike in their attempt to cross the boundaries between persons. Passing does not only occur racially, but is also likened to the process whereby a writer, like Roth or his proxy Nathan Zuckerman, comes to inhabit the subjectivities of other characters. One effect of these conflations--for example, Nathan standing for Faunia as he dances with Coleman--is to raise the threat of homoeroticism, which for Roth collapses difference with same-sex desire. Such stereotypes are a controversial characteristic of Roth's fiction, which nevertheless continues to draw great admiration.00:00 - Chapter 1.
