WebAlthough the CTT is regarded as a true thesis by the scientific community—see, e.g., [15,16,17], Bowie claimed it was possible to exhibit a function which was not intuitively computable, yet recursive. For preserving the CTT, Ross then argued that computability should be regarded as a non-epistemic concept. WebJan 8, 1997 · The Church-Turing thesis does not entail that the brain (or the mind, or consciousness) can be modelled by a Turing machine program, not even in conjunction with the belief that the brain (or mind, etc.) is scientifically explicable, or exhibits a systematic pattern of responses to the environment, or is ‘rule-governed’ (etc.). WebThe Church-Turing thesis makes a bold claim about the theoretical limits to computation. It is based upon independent analyses of the general notion of an effective procedure proposed by Alan Turing and Alonzo Church in the 1930's.
