I'm not an expert, but I found Roger Penrose's book _Ther_Emperor's_New_Mind_ a
compelling treatise on this very subject.

Based on the proofs provided in the book, I would say that Turing machines
decide nothing.  That's not to say that programs cannot provide approximate
solutions for games like chess, but to me, a solution is not a decision, any
more than IF-THEN-ELSE is a decision rather.

From a different angle, I guess it's also like the Calvinist debate.  If you are
"free" to make the decision, then it is.  If you are compelled to make the
decision, then it's not a decision.  Programs really have no choice.

Regards,
Matt
