But there are some principles that are universal in a general sense. And we can look at those principles and ask each other: Why do you believe that? Now if a Christian gives an answer based on Christian theology it isn’t going to apply to an atheist or a Hindu. You aren’t going to convince a Hindu that he shouldn’t steal your car because God says so. So we need to find out common reasons why we hold to what we do and both agree that they are valid in themselves.
In other words, you want to redefine “universal common sense” as secular atheistic humanism so as to disqualify any point of view that holds to anything but atheism. Yup. Got it.
And given that you don’t want to provide anything like “common reasons” for morality except trivial
we should respect property rights because we should respect property rights, it appears that your constrictions on the discussion are designed from the start to limit discussion to what you yourself approve.
Ergo…
I don’t want one based on theistic principles. Don’t bother writing one.
Speaking of controlling the narrative by fiat.
By the way, Hindus, Muslims and Christians are all very distinct from atheism in that they are all theistic to some degree or other. So you have just written them all out of the discussion by limiting the common basis to atheistic premises.
Last point: providing a theistic ground for morality does not amount to stating “because God says so.” That would be your distortion of theistic morality, but how would you know that since you can’t tolerate any explication of theistic morality from the beginning.
So if you can’t find a reason that we can both agree to why you shouldn’t steal then pick another moral principle. Let’s agree on something.
So why don’t you provide an actual “reason” for why we shouldn’t steal that we can agree upon? It appears you cannot, other than insisting we must “respect property rights,” which merely begs the question.
Perhaps the reason no one, not even you, can provide a “common basis” for morality on atheistic grounds is that there is no such reason. Clearly you haven’t been able to come up with one.
That merely reinforces my point that atheism provides no grounds for morality at all. If it did, I am certain you could have come up with something. So far, nada.
The tragedy of common sense might be inbuilt into the tragedy of attempting to use atheism as the ground for morality when it just isn’t possible. That might also be the reason why most, if not all, successful cultures in history have been cultures based upon some transcendent purpose or other; and why 97% of human beings in history have been something other than atheist.
