Parfit's Ethics (manuscript)

Over the last few months, I've been working on a short book manuscript on Parfit's Ethics, for Cambridge University Press' Elements in Ethics series.  I've finally completed a (rough) first draft, which interested readers can view or download here.  (Comments welcome!)

The chapters cover:

1. Rationality and Objectivity
2. Distributive Justice
3. Character and Consequence
4. The Triple Theory
5. Personal Identity
6. Population Ethics

I've always thought that Parfit's Reasons and Persons contained the highest ratio of important insights per page of any philosophical work.  It stands to reason that a summary of this work, if done well, might be able to surpass that record.  So that's my (overly ambitious) hope for this little book.  On the other hand, Parfit's work notoriously defies easy summary.  So... see what you think.
