- My guess is that there are far more assumptions in this than you
- are letting on, many hidden.
-
- However, getting back on track it is silly to say that a theory that in
- some sense avoids internal inconsistency has passed some sort of
- valid scientific 'test'. It's like patting oneself on the back
- for not having assumed ii equals 3 and ii equals 5 at the same
- time.
