Turing was captivated by the potential of the computer he had conceived. Although his 1936 work had shown the absolute limitations of the computable, he had become fascinated by what Turing machines could do, rather than by what they could not. He had long abandoned his youthful expectations of finding free will or free spirits through quantum mechanics. His later thought was strongly determinist and atheistic in character. And by the end of the Second World War he had turned against the tentative idea that there were steps of 'intuition' in human thought corresponding to uncomputable operations. Instead, he held that the computer would offer unlimited scope for practical progress towards embodying intelligence in an artificial form.
