Perhaps I misunderstand. Not sure what you're saying, but ponder
this: If theory is assumed correct, but there is no empirical
evidence to back it up, I agree that the theory was not directly
helpful. (Indirectly the theory can still be useful. It isn't
possible to prove every theory correct [theorem?]). Conversely,
however, if practice and use reveals that something works, why
does it matter what the theory says? That part does not make
sense to me. If it works, it works!
