Passage 228a7-8 of Plato’s Sophist has been the object of a broad debate by reason of a number of subtle interpretative problems. The present work attempts to take stock of this passage and to put forward a satisfying solution from both a philological and an exegetic perspective. I seek to show that the reading cited by Galen and adopted in the editions of the Sophist (τὴν τοῦ φύσει συγγενοῦς ἔκ τινος διαφθορᾶς διαφοράν) cannot be preferred to the variant found in (...) the manuscripts of the dialogue (τὴν τοῦ φύσει συγγενοῦς ἔκ τινος διαφορᾶς διαφθοράν). As for the interpretation, both readings stand out as problematic. I propose to reconsider the interpretation of the syntagma τοῦ φύσει συγγενοῦς and to translate it as “the natural kinship” rather than as “what is naturally kindred”. The paper continues with an analysis of the role played by kinship in Plato’s philosophy, showing how its sundering can be identified with stasis. (shrink)
