Turing wasn't committed to representationalism
Turing leaves open the question of whether the representational account of intelligence is valid. In fact, in some passages—where he discusses learning machines—he seems to reject the representational view in favour of connectionism.
Moreover, Turing woud have denied that an "autonomous" account of intelligence could be abstracted from the underlying mechanisms of intelligence, for:
"he was a hopeful mechanist through and through".
