Bill takes Q & A's on his website so I just submitted this one:
Bill, in your debate with Sam Harris you claimed God was the grounding of objective morality. That word "God" is problematic though. Until that word is defined, or until you tell us how we know what this "God" wants us to do, or what it is, what you end up saying is that there is an objective grounding to morality, and that's it. But then Sam Harris agreed with you on that score.Think he will answer it?
What do you say to someone who claims this debate was just about semantics, that is, you both agreed there was an objective grounding to morality, but that the real debate concerned how you each defined the word "God"? Sam does not like that word, nor does he use it, and he would vehemently deny that the word applies to his grounding for morality. But what would you say to the objection that the debate was about what that word means, and you never told us anything about this "God" or how we know what "God" wants us to do, or what it is, so all you argued is that there is an objective grounding to morality, and that's it, in agreement with Harris. And since Harris attacked your notion of God repeatedly he won that debate.
