If someone had a definitive proof that God did not exist (an argument so powerful it became universally accepted, like when Copernicus proved that the sun did not orbit the Earth), which of these scenarios would be most likely: 1) Most people would run out to have drunken orgies, and in general, live lives of utter debauchery; or,2) we'd enjoy an age of unprecedented enlightenment because mental energy would no longer be wasted on the distortion of a grand delusion; or, 3) A combiation of both A and B.
I am not a sociologist, so I'm not going to make a prediction. But perhaps you can make your own. When you care for the members of your family and your friends, when you are kind to your neighbors, and when you avoid performing random acts of cruelty toward strangers, are you acting out of fear of eternal punishment from God? Or are you doing it out of (dare I say it?) love for your fellow human beings?
