We hear that argument a lot, and though some people’s charity may be motivated purely by egoism I don’t think it applies to the majority at all. The argument assumes that if doing something makes you feel good, then that feeling must be the sole motivation for that action, which is dubious. And if we follow this logic to its natural conclusion, every action that does not make you feel bad is egoistic, and the concept becomes completely meaningless. Saving a child from falling down a cliff? Egoistic! Intervening when someone is treated unfairly? Egoistic! Giving up your chair for an elderly person on a crowded bus? Egoistic!
Let’s take this last (admittedly small, everyday, non-dramatic) example. Sure, you could give up your seat purely because you want to look like a good person to others (although it’s doubtful anyone would even notice). It’s also possible to experience this feeling called empathy, to see an elderly person struggling to keep their balance while standing up and to want to alleviate that particular suffering. Everyone else is sitting down looking at their phones, so there’s no community pressure to speak of. No one would call you out if you just pretended not to notice. And the discomfort from standing up on a really crowded bus on a bumpy road could easily outweigh that little buzz you get from doing good.
I’ll go even further; it’s even possible, in a scenario like this, to not even think about how it’s going to make you feel or your self-image or whatever. You just want to help someone else because it’s in your power to do so. If this isn’t an example of not being egoistic, what would be? What would be the opposite of egoism? To act completely dispassionately?
And what about someone sacrificing their own life to save another? Striving to do good in the world does feel better, yes, but empathy is also a burden. Still, there are genuinely good people out there, that do good deeds and do not take any credit for it, even do it anonymously. And I can tell you from experience, not all of them walk around on clouds feeling like saints. Some of them even experience crippling guilt because they feel they do not do enough. How is that egoism?
