​It is insufficient to explain what a computation is, what is needed is an
explanation of how to perform a calculation. In textbooks on arithmetic it
will say something like "take this number and place it in that set"  but
how do I "take" a number and how do I "place" it in a set without matter
that obeys the laws of physics? In fact who is that textbook talking to if
it's not a collection of atoms that obeys the laws of physics. And I still
don't see how you can be blithely talking about the set that contains all
true mathematical statements and no false ones when you must know there is
no way to construct such a set even in theory.      ​

​Oh dear, we're back to that again. Now where did I put my rubber stamp, I

 Wow, calling a guy known for disliking religion religious, never heard
that one before, at least I never heard it before I was 12.
