“If mindless atoms control my [x], then I have no reason to trust them.”
[x] was originally ‘thoughts’, but could equally well be ‘parachute’, ‘self-driving car’, ‘ladder’, ‘central heating’, ‘watch’, ‘rain gauge’, and myriad other items for which no-one would hesitate to reject that claim. If it’s accepted for ‘thoughts’ it can only be because that claim was invented solely for convenience, and its validity is irrelevant.
