¹ These clipped and flippant summary dismissals will pass only in a review. An adequate treatment of the faults of the Turing argument would involve some tough and sustained analysis, extended trips into Kripke land, for example; something for which most AI workers have neither the time, inclination nor perhaps the philosophic stamina.

² No doubt there will be some who think that I have here laid myself open to a tu quoque retort. However I think that a careful and dispassionate reader of ‘How to Tell Your Friends from Machines’ (Mind, 1972)Google Scholar will see that apart from a somewhat mischievous epigraph from Hobbes the notion of madness enters into the argument in a different way and is not laid as a charge against anyone either named or unnamed.
