For instance, the same wind could be cold to one person and hot to another. The extent to which Protagoras’s view, or at least what comes down to us from Plato, amounts to genuine relativism remains somewhat controversial. As Burnyeat (1976b: 172) notes, Sextus Empiricus thought—though Burnyeat thinks mistakenly—that the Protagorean measure doctrine was to be understood as the subjectivist thesis that every appearance is true (simpliciter).
