No, the logical inference is that I'm arguing against free will. But, truth be told, it's as Devil's Advocate. I'm not actually sure which way I go on free will; I'm simply trying to follow the logic to see where it leads. I'd appreciate it if you wouldn't tell me what I'm doing. That is not conducive to good faith discussion. I'm afraid I don't really know what you mean by substrate. It is not a metaphor I associate with discussions of free will.
