The book is by William MacAskill, founder of 80000 Hours and Giving What We Can. Excerpt:
Effective altruism takes up the spirit of Singer’s argument but shields us from the full blast of its conclusion; moral indictment is transformed into an empowering investment opportunity...
Either effective altruism, like utilitarianism, demands that we do the most good possible, or it asks merely that we try to make things better. The first thought is genuinely radical, requiring us to overhaul our daily lives in ways unimaginable to most...The second thought – that we try to make things better – is shared by every plausible moral system and every decent person. If effective altruism is simply in the business of getting us to be more effective when we try to help others, then it’s hard to object to it. But in that case it’s also hard to see what it’s offering in the way of fresh moral insight, still less how it could be the last social movement we’ll ever need.
I don't think that's the case. Karma based moral systems work quite well without it.
There a scene in "The way of the Peaceful Warrior" where the main person asks the wise man why the wise man doesn't do something substantial with his life but works in filling station. He replies that he's "at service" in the filling station. The act of being "of service" is more important than the value created with it. It's especially better than "trying" to do something from that perspective.
Agreed. Is there a particular reason this is a reply to my comment and not at the top level? Is it intended to support my point via another line of argument?
