Just thinking about AB's approach here of demanding that people at least consider the possibility of his conjecture about "soul".
It give him two problems I think:
First, by positing a conjecture that's inherently contradictory (not determinative, not random but, um, well, you know, kind of...it's a mystery innit, oh is that time already? etc) he's asking us to entertain the possibility of the equivalent of a four-sided triangle. That is, no-one can consider the possibility of a claim that's inherently incoherent - it's just white noise, so there's nothing to consider.
Second, if ever he could manage to make the claim "soul" coherent though then in principle at least he'd be pushing at an open door in any case. "Soul", unicorns, leprechauns, whatever are all possibilities. His mountain to climb though would be to to find a way to elevate one of these from possible to probable.
