The S&M paper.
Seriously. My paper topic for the criminal law theory class is sex, violence, and consent. Should the State prohibit consensual sexual violence (my answer: yes) and if so why (my tenative answer: because procreation is the one purpose which legitimates any sexual behavior). This involves several interesting lines of inquiry, all very much on a political theory/ethical level. I expect to interact with feminist legal theorists at some length (who actually serve as a useful "stick" on this issue) and well as to try to pull some sort of natural law argument out of my old friends Vitoria and Aquinas. :) And I'll probably invite Kant, Locke, and Hobbes to the feast. Should be very interesting.
