I was recently introduced to utilitarianism, more precisely, Mill's Utilitarianism, because I was assigned to do a speech on it for a class. I found the work fascinating and frustrating, and I immediately sought my professor and the library for help in better understanding Mill's views. I found the book by Lyons and I've been engrossed by it. The different critical essays on different parts of utilitarianism have made it so much more clear to me. I like how there are essays with different takes on utilitarianism, some that argue for/against rule-utilitarianism, or for/against act-utilitarianism, and some that just explain it in more depth without choosing a side. This book and Mill's own Utilitarianism are the only books I've read so far, but both are excellent.

Can someone recommend good books on Bentham's Utilitarianism?
