Ἐκ τῆς ἀφ’ ἑνὸς σχέσεως, λέγω δὴ τοῦ Ἡρακλέους. Καθὸ πάλιν δύο σχέσεις λαμβάνονται ἑνὸς πρὸς ἕνα, αἰτίου καὶ αἰ- τιατοῦ, οἷον τοῦ Ἡρακλέους πρός τινα τῶν Ἡρακλειδῶν (αἰτίου μὲν ὄντος τοῦ Ἡρακλέους αἰτιατοῦ δὲ τοῦ ἀπ’ ἐκείνου), ἢ τῆς πατρίδος καὶ τοῦ ἐν αὐτῇ τραφέντος, καθὸ λέγομεν Πλάτωνα μὲν Ἀθηναῖον τὸ γένος Πίνδαρον δὲ Θηβαῖον. ἰστέον δὲ ὅτι ἡ σχέσις λέγεται ἢ κατὰ τέχνην ὡς τοῦ διδασκάλου πρὸς τὸν μαθητὴν ἢ κατὰ τύχην ὡς τοῦ δεσπότου πρὸς τὸν δοῦλον ἢ κατὰ προαίρεσιν ὡς τοῦ φίλου πρὸς τὸν φίλον ἢ κατὰ φύσιν ὡς τοῦ πατρὸς πρὸς τὸν υἱόν· ἡ οὖν τῶν εἰρημένων σχέσις φύσει ἐστί.
