Full Idea
In his earlier work, Quine defended the view that no belief (including logic) is in principle unrevisable, but in his later work (1970) he took the conservative view that we would always impute mistranslation rather than deviancy.
Gist of Idea
Early Quine says all beliefs could be otherwise, but later he said we would assume mistranslation

A Reaction
I take it he was influenced by Davidson's 'principle of charity'. He says that if someone asserts 'p and not-p', we would assume a misunderstanding of 'and' or 'not'.
