And secondly, how on earth are the terms selfish and selfless useless? They specifically describe personal attributes that relate to ones attitude to other people. Does one act purely for one’s own benefit or for the benefit of others. Surely, this is about as basic as you can get.
No, it is not as basic as you can get. And merely looking at the things you wrote is sufficient to see it. “Benefit” is obviously more basic than “selfish” and “selfless”.
As I see, you already chose a definition where an act is selfish or selfless if one does “act purely for one’s own benefit or for the benefit of others”, instead of the one I gave ("[a] ‘selfish’ action is one that benefits (or is seen to benefit) one who performs it in some way").
Good. That is an improvement, and some of the “work” I talked about.
And yet, it is not sufficient.
Let’s take an example. Presumably you ate today, this week, this month, this year. Was that a “selfish” action? Let’s check by the definition… It does look like you ate for your own benefit, and not for the benefit of others - or are you willing to claim otherwise?
So, did you perform a “selfish” and thus evil action by eating? Are you supposed to stop eating?
Hopefully, you will agree that no, eating is not an evil action.
But then, if it is so easy to find an action that is “selfish” and yet not evil, then you will have to modify the definition of “selfish” once more, or to decide that some “selfish” actions are not evil - and thus, category “selfish” is mostly useless, as it does not seem to have many other uses.
