On Antinatalism So you think that it is so obvious that procreation is ethical that any argument that leads to the contrary conclusion must have a false premise?
Okay, but what if the best explanation of why most people get the rational impression that procreation is ethical has nothing whatsoever to do with its actual ethics? I mean, there's a pretty obvious explanation of why virtually all humans get the impression procreation is ethically fine - only those whose ancestors got that intuition would breed.
That's similar to the intuition, again widely felt, that there is something immoral about homosexual relations. Why do many people - often people with homosexual dispositions - get that impression? Well, because it would be adaptive. If you have a homosexual disposition but also think it would be wrong to act on it, and bad to have it, then you'll try hard not o act on it and to focus and cultivate your heterosexual dispositions (and acquire all the standard heterosexual attributes, such as a partner of the opposite sex and lots of offspring). Hence why the intuition that homosexual sex is immoral gets selected for, and why we find it associated with possession of homosexual dispositions.
Now, does that show that the intuition should be taken seriously? Does it show that homosexual sexual relations are, in fact, immoral?
No, the opposite - it discredits such intuitions. It does not vindicate them, it debunks them. Likewise with the intuition - widely felt - that procreation is morally fine. It's pretty obvious why most people get it: anyone whose ancestors did not get it would not have procreated.
