There are no "virtue, ethics, or morality" without G-d.
Then there are no virtue, ethics, or morality with God, either.
The commands and pronouncements of a god, if moral, would point to an external morality that would be accessible without the god.
OTOH, if the commands and pronouncements of a god aren't based on anything other than his own whims, then how can they be said to be moral at all?
Today's virtues are tomorrow's perversions without G-d.
And yesterday's perversions are today's virtues without G-d.
Every culture's views on morality have changed over time, regardless of whether that culture is religious or not.
Nonetheless, I was pointing out that Purpose is what has mattered for the last several thousand years.
The purpose of your belief or non belief in "how many of a given type of supernatural entity... [and] questions of virtue, ethics, or morality" is to excel in This World; this material existence.
Which is fine. You should live and be well.
Don't presume to tell me what my purpose is.
My point still remains that this fixation on This material World to the exclusion of G-d is a very recent phenomenon.
Or, to put it is modern terms - Belief in the material world of the senses to the exclusion of the non material world that cannot be proved by science, is an extremely young, and therefore untested and theoretical "scientific" belief.
You're arguing against a straw man. Nobody believes that things outside the scope of science don't exist.
The closest thing that people actually believe is the view that for a belief to be reasonable, it should have a rational justification... and what's wrong with that, exactly?
It's not that things that aren't scientific don't exist; it's that if you don't have a rational basis for your claims, you're making stuff up. Could you coincidentally stumble on the right answer without any rational basis for your position? Maybe - a stopped clock is right twice a day, after all - but I'm not putting money on it.
