A nice quote from Engels in Mr Tao Xiping's talk on the Strategic Value of ESD and its Future Development:
"We are punished for every victory over nature."
It would be nice to think so, as would be the notion of a reward for every act of empathy. The latter is more likely at the personal level than the former, hence the nature of the problem of the human – nature problem: private benefit and public cost.
As I don't really know my Marx from my Engels, and I cannot find this quote, I cannot swear to its authenticity or context.
