An interesting snippet from Wiggs recent link:
J. B. S. Haldane, who appeals to a similar line of reasoning in his 1927 book, Possible Worlds: "If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to suppose that my beliefs are true ... and hence I have no reason for supposing my brain to be composed of atoms."
This argument seems to lead to ultra-skepticism, not only about humans but also animals. For example, if you take an animal such as the leech, it relies on sensitive sensory equipment to indicate possible food sources (blood), possible dangers, places of safety, potential mates, and so on.
But these sensory organs and the nervous system which coordinates the information, are made up of atoms, I assume.
So how can they be reliable?
The argument seems to amalgamate the fallacy of composition, and arguments from ignorance and incredulity. On top of that, it is quote-mined. Bingo!
