Query: On Empirical Equivalence and Duality   I argue that, on a judicious reading of two existing criteria--one syntactic
and the other semantic--dual theories can be taken to be empirically
equivalent. The judicious reading is straightforward, but leads to the
surprising conclusion that very different-looking theories can have equivalent
empirical content. And thus it shows how a widespread scientific practice, of
interpreting duals as empirically equivalent, can be understood by a thus-far
unnoticed feature of existing accounts of empirical equivalence.
