Heads up for an interesting taxonomic approach to the antinatalism question. Sister Y has classified the major positions thusly-
1: Pronatalism. "All reproduction is morally innocent (or morally required)."
2: Situational context-dependent antinatalism. "Everybody should have babies except starving people in the third world, drug addicts, and AIDS patients."
3: Universal context-dependent antinatalism. "Our world is so bad that no one living in it should reproduce; but if things got much better, it might be okay."
4: Pure antinatalism. "No beings should ever be brought into existence if they will suffer at all - which they will."
Obviously, 1 and 2 are off the table as far as I'm concerned. 3 is no more tempting for a couple of reasons, the most obvious being that life exists in a constant state of existential flux. Having achieved utopia, what possible guarantees of everlasting prolongation can be secured? Shit happens. Beyond the question of endurance, there's the matter of those lives brought into being between then and now- how can the coercion and sacrifices ever be justified within a normative moral framework? There's also the problem of varying subjective standards to deal with. How can we know that our little utopia will measure up to somebody else's future measuring stick, unless everybody is exactly the same? It's been tried before.
Now onto number 4, and a question that's never really occurred to me before. What IF, in a far distant future, some paradise is manufactured which is somehow guaranteed to be both sufficient for all and sustainable throughout eternity. Imagine a day when suffering of any sort is abolished once and forever, swept out of the universe like a herd of unwelcome dust bunnies. Under these conditions, would procreation automatically become a moral act? Why? Perhaps it could be said to be not an immoral act, but I'm not so sure this is the same thing. Is a harmless act automatically a moral one? Or does a moral act entail some substance or form of moral necessity, no matter how oblique? I may be splitting hairs here, but equating non-immorality with morality is leaving me just a little bit queasy...perhaps for no good reason, I'll confess. It's an open question, and I invite debate.
UPDATE: The reason I bring this up is because it occurs to me that all purposeful action requires, or is impelled by, SOME sort of necessity. In a theistic context, the question has always been IF God is entirely sufficient unto Himself, what could possibly provoke Him to an act of creation? The pat answer has always been that He does such for His own pleasure; but of course, wasn't He always perfectly 'pleased' to begin with?
Pursuing this line of inquiry to its outer limits, I am logically persuaded to conclude that absolute perfection- or purity, if you will- when defined under the aegis of unalloyed non-necessity, doesn't look a whole lot different from non-existence to me. If, indeed, there's any difference at all. It seems to me that a positive moral action is always conceived to fill a gap, the kind of gap which just doesn't exist in a fundamentally ideal state (or non-state, in the case of non-existence). Which brings us full circle to the concept of Negative Bliss. The place where we started. The place we're all headed back to, eventually. In this light, existence seems to be nothing more than sediment temporally shaken up from the bottom of a crystal clear lake otherwise untroubled by any eddies, or winds of chance. Why muddy the waters?
