Le sophiste et les exemples. Sur le problème de la ressemblance dans le "Sophiste" de Platon

In the Sophist Plato introduces a very peculiar character, the eleatic stranger who plays both for Theaetetus and for us the role of a perfect sophist. His terrific power simply comes of his refusal to understand the examples. He just requires his interlocutors that absolutely all what is to be understood by them must be explicitly said. And “all” means really all: even the most evident for everybody, all what is not necessary to say and perhaps is not possible either. The eleatic visitor, in order to hunt the sophist whose role himself is playing, trays to say all indeed, even the most difficult: the meaning of words as being, not-being, same, other or similarity. In this way, the language shows oneself as a play of likeness and unlikeness
