Abstract
The argument by which the Eleatic Stranger differentiates the kinds being and different (255c9-e2) is one of the most controversial in Plato’s Sophist. In it the Stranger introduces the vexed distinction between beings that are auta kath’ hauta, ‘themselves according to themselves’, and those that are pros alla, ‘relative to others’ (255c13-14). Although commentators have developed many interpretations of the argument, there is a key yet hitherto unrecognized ambiguity in the syntax of the counterfactual conditional at 255d4-6, concerning whether the adjunct comparative clause, hōsper to on, should be adjoined to the protasis or apodosis. Editors from Heindorf to Robinson adjoin hōsper to on to the protasis. I argue this is mistaken. Adjoining hōsper to on to the apodosis instead allows for a more straightforward interpretation of the argument and offers a resolution to the controversies surrounding the ‘according to themselves’ / ‘relative to others’ distinction.
