Cultures are not the source of all morals, only a limited set of morals. Cultures can be graded and judged morally according to their contribution to the evolution of life.
Robert M. PirsigThe TV scientist who mutters sadly, "The experiment is a failure; we have failed to achieve what we had hoped for," is suffering mainly from a bad script writer. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don't prove anything one way or another.
