Eternal Truth by Convention

Within the epistemology of the sciences, conventionalism
has been the subject of regular criticism for over six
decades. Critics such as W. V. Quine and Morton White,
and more recently Nathan Salmon (1992), and Paul
Boghossian (1996), have attacked even the most basic
tenet of conventionalism, namely its claim that the truth of
certain statements is fixed not by stipulation-independent
facts, but by the conventions governing the meaning of
those statements and their constituents.
