Stephen Jay Gould said this quote

There are no shortcuts to moral insight. Nature is not intrinsically anything that can offer comfort or solace in human terms -- if only because our species is such an insignificant latecomer in a world not constructed for us. So much the better. The answers to moral dilemmas are not lying out there, waiting to be discovered. They reside, like the kingdom of God, within us -- the most difficult and inaccessible spot for any discovery or consensus.
