Slave codes and obligation papers

I can't tell how many papers this will be, but five topics are attracting five clusters of argument in my notes and my thinking:

1. Ex persona domini obligations. [Holmes]
2. Uncertainty in rules of obligation. [Hart]
3. Stasis in rules of obligation. [Hart]
4. Inefficacy/inefficiency in rules of obligation. [Hart]
5. Thrasymachus-style power arguments and the slave codes. [Plato]

I'll see if I can get 5000 words in good enough shape to show around by the weekend.
