I think as time goes on, I am learning that humans are dissatisfied because they no longer know how to live the life of a human, where (wild) pigs are fully capable of living the life of a pig. The big eye-opener for me was "The Story of B", by Daniel Quinn. Say what you want about the completeness or quality of its anthropology, it has touched on an ineffable fact that we are constantly trying to use more of what is bad for us to try to make it good.
