Refutatio Omnium Haeresium (= Philosophumena)

Καὶ γὰρ καὶ Παρμενίδης ἓν μὲν τὸ πᾶν ὑποτίθεται τε καὶ ἀγέννητον καὶ σφαιροειδές, οὐδ' αὐτὸς ἐκφεύγων τὴν τῶν πολλῶν δόξαν, πῦρ λέγων καὶ γῆν τὰς τοῦ παντὸς ἀρχάς, τὴν μὲν γῆν ὡς ὕλην, τὸ δὲ πῦρ ὡς αἴτιον καὶ ποιοῦν. τὸν κόσμον ἔφη φθειρεσθαι, ᾦ δὲ τρόπῳ, οὐκ ἐἶπεν. ὁ αὐτὸς δὲ εἶπεν ἀΐδιον εἶναι τὸ πᾶν καὶ οὐ γενόμενον καὶ σφαιροειδὲς καὶ ὄμοιον, οὐκ ἔχον δὲ ἐν ἑαυτῷ, καὶ ἀκίνητον καὶ πεπερασμένον.
