I'd have thought being moral is about oneself not others?
Oh no...of course not. This is the moral solipsist fallacy.
Why would we even bother with the category "moral" if you were the only person on earth? If there were no God, no other people, and not even any other animals that one regarded as relevant to a moral decision, then one would simply have no use for moral language at all. One could not even talk sensibly about "morality" to oneself, then...for how could one "owe oneself" any explanation for a choice made or action taken? And to whom would the moral appeal be made?
The truth is that morality only comes into play when there are at least two persons or morally-relevant entities in view.
a moral obligation upon oneself
To whom does one owe this obligation? If one prefers to be a self-abuser, or if one simply chooses to be lazy rather than take any action at all, of whose rights has such a one run afoul? To whom will one explain, or justify his actions? Again, this is the solipsist fallacy.
My take is that Atheism supports any moral system one cares to choose.
If so, explain what you mean by "supports." Do you mean merely "allows for," or "actively endorses"? If you mean the latter, you're wrong. As CL notes, slender atheism does not endorse any choice at all.
I think a meritocracy just obviously the most rational approach if one wants to find the best to do the best job and all doing the best they can at what they can.
I think by "rational" you must mean "the one I prefer." Unless, that is, you can provide a syllogism to support meritocracy, and so show that it is uniquely "rational," (i.e. the one that reason itself requires.)
I'd have thought a true liberal democracy would be one where equality of opportunity allows the meritorious to achieve their aims?
No, not at all. You are, perhaps, describing libertarianism, but not democratic liberalism. Democratic liberalism struggles between equality-of-opportunity and equality-of-outcomes, which are often in conflict, and general seems to favour some version of "equality-of-outcomes" -- i.e. that the weak or disadvangaged should be given additional advantages to compensate them until they attain equality with the strong and advantaged. So democratic liberalism would accept things like taxation and social programs, whereas meritocracy would argue for free competition, with winners being granted as many privileges as they can merit.
What are the 'weak' in this case? Whatever their are why would their be any resentment towards them?
The "weak" in this case includes anyone who through any factor is at a disadvantage relative to the meritorious person. So it includes people disadvantaged by physical strength, disability, lack of intelligence, lack of opportunity, lack of money, lack of health, lack of knowledge...and so on. In short, anyone guaranteed to be at a disadvantage if we have a meritocracy.
No one would need to "resent" them; they'd fall behind naturally, and be harmed thereby automatically, since they would -- as you can see above, perhaps even for reasons they could not control -- never be able to rise to the level of the advantaged through mere merit.
the individual-of-merit(although I'm puzzled why all aren't such things in some case?) still needs a thriving of the society they swim in to survive.
No again. Depending on what "thrive" is taken to mean, a society could do very nicely with a whole lot of people on the low end of things. Southern American plantations did very well with slavery, in many cases. As Hitler showed, a fascist society could expedite the construction of public projects and achieve equally a high degree of efficiency in building cars or killing people.
So there's no reason to think that meritocracy needs a society "thriving" only on terms we find moral or congenial. If it "thrives," it's good enough to work, even if "thriving" is on evil terms.
I thought the OP was about how society would be worse-off without theism not with atheism?
It started that way: but do you really suppose it would be rational to embrace the alternative without weighing it rationally first? That's all we're doing; we're comparing the claim that atheism's a "better" alternative, in some sense.
In particular, we're looking for evidence that CL's slender version of atheism has something to offer by way of an advantage over "religion," even delusory "religions." But so far, we're realizing that slender atheism offers no particular advantage at all. It's only supposed advantage is that it negates "religion," which would be no advantage at all if, as the thread suggested at first, "religion" (again, even delusory "religions') brings social benefits.
Slender atheism has none at all, it seems. As CL says, it advocates nothing particular positively, only a negation of "religions." Why, you yourself even admit this...see....
You're right, and thats because it's a disbelief in what the theist claims, not a belief in anything.
As such the warrant for a meritocracy rests in the reasoning of its citizens. I guess that's partly why it'd be a good thing for region to vanish as no more props or excuses for why things are as they are because they are as they are because we don't think it's a choice.
Now you're onto something. Slender atheism offers nothing, so it has to be fortified by the bringing in of some ideology to provide the positive information it lacks. So it needs something like Libertarianism, Naturalism, Scientism, Humanism, or some other secular ideology or pseudoreligion to do the work it could not do itself. Atheism clears the ground for these, but does not determine which we must take...it only says that whichever it is, it cannot be one that depends on the premise that God exists.
But atheism provides equally clear groundwork for Dialectical Materialism (Marxism), Libertarianism (or meritocracy, if you prefer) or for Fascism, or for whatever ideology one wishes to plug in. The combo of slender atheism plus secular ideology I would term "thick" or "expansive atheism," and contrast it to CL's version of atheism because it is no longer mere atheism but something else as well.
I don't, I think it a necessary corollary of being able to choose and prefer the choice to be a rational or reasonable one based upon what kind of society one would prefer to live in.
So if I found it reasonable and rational for my meritocratic interests to live in a slave society, or perhaps in one that liquidated its gypsies and handicapped, would that all be fine?
