To rephrase in part, if I may
1) In a universe where everything is determined, all things would, of course, be determined
2) and so all theories would be determined, and thus there could be no theories of in-determinism.
Just to be clear here "theories
of in-determinism" (in other words,
about indeterminism) does not mean such theories would not be concocted deterministically. Like all other concocted theories, such a particular theory would also have been determined. It doesn't matter what a theory is about in order to have been determined by prior cause/effect events. So, your contention that,
"Seeing as though we do have theories of in-determinism, it follows that not everything is determined"
is erroneous.
If you have any issue with either of my rephrasings, please point them out by line. Either 1) or 2) as labeled.
