"My gavagai example has figured too centrally in discussions of the indeterminacy of translation. Readers see the example as the ground of the doctrine, and hope by solving the example to cast doubt on the doctrine, The real ground of the doctrine is different, broader and deeper.

" the same old empirical slack, the old indeterminacy between physical theories, recurs in second intension. Insofar as the truth of a physical theory is underdeterminated by observables, the translation of the foreigner's physical theory is underdeterminated by translation of his observation sentences. "
