most moral codes claim to lead to well being, but in reality many of them do not actually go there.Good points. It's a tough subject and, well, it's open to interpretation. That's the problem.
As a counter-example, I'd offer up Mother Theresa, who suffered a lot and had severe doubts both about her faith and her work, yet most outside observers believed she was a moral person. I would also offer up early Christians, which surprised the Romans at being more than willing to tend to people stricken by the plague. To them it was the moral thing to do.
Moving to the stoics, it's a common belief among them that you train yourself to enjoy life more by purposely taking away things from yourself: sleep on the floor, or try skipping a couple of meals.
The point is that there is no point. You can look at this short-term, medium-term, long-term, from the point of view of the individual, community, country, or species. Or you can imagine some ethereal world in which important things don't align with any physicality. Good arguments can be made for each of these viewpoints.
Hell, it may be that the reason things are generally more or less moral than others is that they promote advancement of the species as a whole, in which case to truly understand morality you would have to be able to understand the social, political, and technological dynamics of 4+ billion people interacting with one another. It could simply be incalculable.
Beats me. I just wanted to provide a counter-example. Your point is as good as any.
BTW, I've also observed this you notice as well, and it's very sad. Perhaps a noble goal of science would be to help folks identify these cognitive dissonances, both in themselves and in their work. I have a feeling it's much more prevalent than we imagine. Always easy to find the fault with the other guy -- much tougher to find it in ourselves.
