I think the asymmetry is this:
Scenario A. Person exists: Presence of benefit = good, Presence of harm = bad
Scenario B. Person does not exist: Absence of harm = good. Absence of benefit = not bad
By not procreating we can prevent suffering without depriving anyone of good. So there is net benefit. — Cuthbert
I am not disputing what it is. I am arguing that it lacks justification.
"The asymmetry cannot be properly explained and it is a special case of a more general asymmetry." — Cuthbert
That's
not a quote from me!! Where did I say that? If you put quote marks around something you're saying it is a quote - but you wrote that sentence, not me!
But if he can establish that the asymmetry also exists in the special case then that is enough for the argument to work. — Cuthbert
No, he is positing his asymmetry as a 'best explanation' of our intuitions about particular cases - the happy life and miserable life cases. So, it is not in dispute that we have a positive obligation not to create the miserable life, other things being equal, and that we have no positive obligation to create the happy life, other things being equal. What he's saying is that the 'best' explanation of those intuitions is the asymmetry he appeals to.
But that asymmetry is 'not' the best explanation. Why? Because a) it isn't an explanation at all, as all he's doing is saying "let's suppose it is an instance of a more general asymmetry" - how's that an explanation of the asymmetry? It is, as I said, like me asking "how is this watch working?" and being told "well, it is just an instance of a working watch".
And b) because Benatar's asymmetry makes it central whether we pre-exist or not - yet whether procreation is moral or immoral should, intuitively, be unaffected by such matters.
And c) because we can explain the asymmetry by appeal to self-evident truths of reason about desert.. The explanation of why we have no positive obligation to create the happy life is that the happiness in question is non-deserved and thus we have no positive reason to perform an action that generates it. By contrast, we have positive obligation not to create the miserable life because the misery is undeserved and we have positive reason not to perform acts that create undeserved harm.
"We might pre-exist and suffer harm from not being brought into existence." — Cuthbert
Where did I say that? If you quote someone, you have to use their actual words (obviously!).
True, we might, but it's a big assumption and we have no way of telling whether it's true or false or how happy or unhappy pre-existent persons may be. So it should not figure in our calculus of happiness. — Cuthbert
That's the point! So, whether we pre-exist or not should have no bearing on the morality of procreation. It would if we knew what pre-existence-here life was like, but we don't. So, given we don't, it should make no difference to the morality of procreation. Benatar's asymmetry makes it matter though. Thus, Benatar's asymmetry is unreal. That's one of my arguments.
1. If Benatar's asymmetry is real, then it makes crucial difference to the morality of procreation whether we exist prior to coming into existence here or not, other things being equal
2. If other things are equal, it makes no difference to the morality of procreation whether we exist prior to coming into existence here.
3. Therefore, Benatar's asymmetry is unreal
I gave a reason why the asymmetry, despite being valid in consideration of people as consumers of pain and pleasure, fails when we add their role as producers. The pain of a childless couple can be mitigated in one way only. — Cuthbert
Irrelevant. That's not a criticism of the asymmetry.
My second argument was attacking the asymmetry indirectly. If asymmetry is sound, then nihilism follows. We already reject nihilism. So we can reject the asymmetry without even knowing in detail what might be wrong with it. — Cuthbert
First, you're misusing words. 'True' or 'real', not 'sound' (soundness is a property of arguments).
And 'nihilism' is the view that there are no norms of reason - that is, that we have no reason to do or believe anything and thus no moral reason to do or believe anything.
An antinatalist thinks we ought not to procreate. Thus an antinatalist thinks it is more important, morally speaking, not to procreate than it is to maintain the species. So all you're doing is saying that the asymmetry must be false becasue it implies the truth of antinatalism.
