Replacing One Theory by Another Under Preservation of a Given Feature
Rolf A. Eberle · Philosophy of Science · 1971
The conditions are examined under which one theory is said to be replaceable by another, while preserving those features of the original theory which made it serviceable for a given purpose. Among such replacements, special attention is given to ones which qualify as so-called reductions of a theory, and some theorems are proved concerning the notion of a reduction.
