Some things I've written -- I'll add more periodically.

Here's my 2005 essay "Superhero Revisionism in Watchmen and The Dark Knight Returns," from Superheroes and Philosophy, edited by Tom Morris and Matt Morris (Chicago: Open Court, 2005).
What did I think of the film version?  Liked it a lot.

Here's my essay on disaster relief, from Liberty and Hard Cases, T. R. Machan (ed.), Hoover Institute Press, 2002.
