And it's funny because the "realism" has been proven wrong over and over and over again for millennia. People do all sorts of selfless and generous things all the time! The entire premise is trivially disprovable by just going and asking a neighbor for some help with something.

That's not to say we should be naive about greed or malice existing or being powerful motivators (especially the former), but it is obviously not true that they're the only forces at play and therefore you are "just doing the logical thing" by succumbing to them. It's just the more destructive version of the same naiveté.

Seems you and I have together struck a nerve. Maybe our sentiments would have been better received in an alternate subthread, but it’s all I could think about while reading the parent / cousin comments.

I haven’t read the full Magnifica Humanitas yet, but I would be pleasantly surprised if he touched on not just dehumanization of the other, but dehumanization of the self. Expanding on your thought, succumbing to those forces under the guise of just doing the logical thing is in a way self-dehumanization - to believe you are only capable of the “logical” thing instead of the moral thing.
