Since there was a thread on Turing:arXiv:1201.4504v1 [math.LO] Here is the abstract: We discuss historical attempts to formulate a physical hypothesis from which Turing’s thesis may be derived, and also discuss some related at- tempts to establish the computability of mathematical models in physics. We show that these attempts are all related to a single, unified hypothesis. comments?

`The author asks if Turing’s Thesis is the Consequence of a More`

`General Physical Principle.`

`So he is unaware of the (comp) mind body problem. It is still a`

`defense of the digital physics thesis, which is non sensical as it`

`should be quasi-obvious for anyone understanding the first person`

`indeterminacy and its main invariance properties. You might ask`

`question if this is not yet clear for you.`

`The opposite thesis is more plausible: the physical principles are a`

`consequence of the Turing thesis. And that is good because the Turing`

`thesis (Church thesis) is more solid on both empiric and conceptual`

`grounds than any primary-physical thesis, which ask for fuzzy strong`

`ontological commitment. Also, the opposite thesis provides perhaps the`

`first rational explanation where the beliefs in the physical laws and`

`the apparent material worlds come from, without assuming a physical`

`reality, nor ad hoc implicit identity theses.`

`So it looks like one more failed attempt to save Aristotle theology,`

`physicalism and naturalism.`

`Note that I am open that Turing thesis is a consequence of a deeper`

`thesis, notably of the thesis of the existence and uniqueness of the`

`standard model of Peano Arithmetic, but that intuition is hard to make`

`precise, and might be using comp at some level (which would make the`

`argument circular).`
