“. . . By Being, It Is, a work which shares with Curd and Hermann the view that Parmenides’ interest is primarily in method; though Cordero takes a more metaphysical line on what the method is for, arguing not only that Parmenides’ poem was not cosmological, but that it makes no sense even to talk of cosmology in a Parmenidean context. The sum of Parmenides’ contention is that ‘that which is being is’ – a thesis explored in the first route described by the goddess. (The second route, identified with the path taken later on by mortals when they mix being with not-being, explores the absurdity of negating this thesis.) . . . the argument itself its powerful, and Cordero’s work invaluable for its reassessment of the textual tradition for Parmenides, which has led him to challenge crucial readings whose speculative roots most of us have forgotten, or else ignore.”
