I noticed you failed to mention utilitarianism, which asserts that there is no better guiding principle for ethical choices than the greatest potential well being (or happiness) of all affected sentient individuals. [This is the one Sam Harris gets accused of 'ripping off' without mentioning it by philosophy types who dislike him.] I've heard and read a whole lotta bluster from people who have nitpicky issues with it, but I find it pretty satisfying.
