Interesting—I had forgotten about that. If one actually assigned a non-trivial probability to the hypothesis that the soul enters the body at conception, one could do the stats to see if chimeras are more likely to exhibit multiple personality disorder!
Or genetic chimeras, who are fused fraternal twin embryos—have they got two souls?

Maybe one of them is dead? The one that didn’t form the brain, I guess.
Although, if you can have a soul at conception, the brain must be unnecessary … hmm, transplant patients …
