I see in the "Recent on Rationality Blogs" panel an article entitled "Why EA is new and obvious". I'll take that as a prompt to list my three philosophical complaints abouts EA:

• I believe in causality as a basic moral concept. My ethical system absolutely requires me to avoid hurting people, but is much less adamant about helping people. While some people claim to be indifferent to this distinction, in practice people's revealed moral preferences suggest that they agree with me (certainly the legal system agrees with me).
• I also believe in locality as an ontologically primitive moral issue. I am more morally obligated to my mother than to a random stranger in Africa. Finer gradations are harder to tease out, but I still feel more obligation to a fellow American than to a citizen of another country, ceteris paribus.
• I do not believe a good ethical system should rely on moral exhortation, at least not to the extent that EA does. Such systems will never succeed in solving the free-rider problem. The best strategy to produce ethical behavior is simply to appeal to self-interest, by offering people membership in a community that confers certain benefits, if the person is willing to follow certain rules.
