A funny thing about Turing's *Computing Machinery and Intelligence* is the discussion of ESP.
ESP seems like a pseudo-science now, but thinking machines were unthinkable in 1950. And the nice thing about this comparison is that they resemble Nicholas of Cusa's distinction of "ratio" and "intellectus."
"Ratio" is discursive comparison, judgment, choice, etc. The kind of thing that no one would argue computers are incapable of doing. "Intellectus" is direct apprehension, like the angels.

I'm suggesting that "ESP" corresponds with the Cusan vision of "intellectus," or direct access from the immediate source of experience. "Ratio," which can be duplicated in machines, involves the discursive operation of the objects within mental experience.
