Where we may differ, mg, is that I tend not to think in terms of "good" behavior vs "bad" behavior. I tend to think in terms of functional and dysfunctional behavior, and to be forever mindful that what is functional in the context of one person's life and resources may well be dysfunctional in the terms of another person's life and resources. I am sometimes paralyzed by the ambiguity that context provides.

I think the world needs people who think like you and people who think like me. I do not think the world needs needs people who think only of themselves, but I also think that people of means who think only of themselves historically have an uncalled for advantage over those people without means who think only of themselves. I am ever preoccupied with the dynamic balance crucial for survival of our species between the individual and the social.

Not sure where Darwin would land on that particular continuum.
