# Re: free will and mathematics

```I'll try to explain why choosing an arbitrary element should be interpreted
as *a free will choice in mathematics*.
The difficulty of understanding  depends, IMHO, on the fact that in English
different roots of the words are employed in "arbitrary" and    "free
will". In Russian thre roots are the same, but my explanation will not base
on this fact.
According to phisics, free will choice (if it does exist) is a choice which
1) is not random,
2) is not determined by some law.
Now , consider a *Theorem: *statement A is valid for all x belonging to X.
*Proof. *Let x be an arbitrary element of X. We demonstrate that A(x) is
valid.
Since x was chosen arbitrarily, A is valid for all x.
*Comment.* As I have pointed out earlier , if x was chosen randomly, the
theorem is not proved.
Analogously, if x was chosen according to some rule, the theorem is not
proved.
Therefore, since we are sure that we have proved the theorem by using the
arbitrarily chosen element, we* must inevitably agree* that
the element was chosen by using free will choice.```
