 The phrase “The Turing Test” is also sometimes used to refer to certain kinds of purely behavioural allegedly logically sufficient conditions for the presence of mind, or thought, or intelligence, in putatively minded entities. So, for example, Ned Block’s “Blockhead” thought experiment is often said to be a (putative) knockdown objection to The Turing Test. (Block (1981) contains a direct discussion of The Turing Test in this context.) Here, what a proponent of this view has in mind is the idea that it is logically possible for an entity to pass the kinds of tests that Descartes and (at least allegedly) Turing have in mind—to use words (and, perhaps, to act) in just the kind of way that human beings do—and yet to be entirely lacking in intelligence, not possessed of a mind, etc.
