Professor Kozlowski over-analyzes the frankly silly Don Juan of Moliere.  He discusses the Don Juan tradition up to this point, as well as dissecting many of the scenes throughout the play.  Along the way he highlights Moliere's criticism of philosophy, religion, medicine, science, love, honor, responsibility, and basic human decency.  It's nihilism before its time, folks, and it will rarely ever be this much fun.
