I looked it up. The physics of the machine is such that state A will
reliably transition to state B. This can either be worked out from
first principles or by experiment, and the results stored in a table.
The entire computation could be done by hand in this way by a human
operator who blindly follows the rules and has no more idea where the
rules came from (or the grander purpose behind his actions) than an
individual gear or transistor does. We need to agree that the causal
link is preserved in (a), with *no* interruption in consciousness,
before considering (b) and (c).
