Yes, AB seems to think that by repeating the word 'physical' as often as possible, he can avoid the logic of cause and effect. And then he says, 'you do not know what the human soul is capable of or how it works'. Well, OK, please enlighten us about this.
It reminds me that Freud is often quoted as saying that mental events have mental causes, although I can't find the quote. But it sounds in tune with his thinking, after he had given up neurology. But he still argues that mental events do have causes, not that they are random.
I suppose AB is comparing the soul with God, that it can initiate things completely out of nothing. But this makes even less sense.
