On the centerpiece page, when you read my claim that morality is the pursuit of Fuiki, did you object that if you're only doing it to feel good about yourself then it's just selfish and not really a good act? Let me refute this objection.
Fuiki is defined as the feeling you get when you do the right thing. But if it's only a good act if you're not doing it for the Fuiki, then not every good act gives you Fuiki - a contradiction. This leaves us with one of two options: either I'm right that it still counts as virtuous if you're only doing it for Fuiki, or it's not possible to do a good act purely for Fuiki. I don't think anyone would argue for that.
This is why I don't like to use "selfish" in philosophy. It's a misleading term.
