I understand your point about randomness but not the idea of a input which
is lacking: surely it then has no influence on the behaviour?

Unless there is choice: if it is the case that choice is not an illusion
e.g. a random, post-rationalised phenomenon, then any FSA won't cut the

Right: we don't know enough about ourselves. However, we do know that
FSAs are either deterministic or have a random component and so definitely
do not choose.
