The bijection material [physical] computation ↔ arithmetical computation is like (New Testament) Paul's thesis: There's earthly bodies and spiritual bodies. "Not all flesh is the same: People have one kind of flesh, animals have another, birds another and fish another. There are also heavenly bodies and there are earthly bodies; but the splendor of the heavenly bodies is one kind, and the splendor of the earthly bodies is another. ... If there is a natural body, there is also a spiritual body." Spiritual or heavenly fictionalism is like arithmetical fictionalism: spirits (like numbers) do not exist. - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
