"Let me also suggest that if "older morality withers" in the light of a mechanistic universe, that there is no morality that can take its place, since there will be no basis for any morality beyond what individuals or localities happen to choose to enforce for whatever peculiar reasons that drive them at that place and time."
It's very sad that so many people can think of no rational, objective standard to live there lives.
Merry Christmas!
Precisely the point.
Each person will think of his own "rational, objective standard."
Or as the bible says, "Each did what was right in his own eyes."
