For a long time, Parmenides was considered the first true metaphysician in history, a theorist of a disembodied being inaccessible to scientific knowledge of the world. Giovanni Cerri, in his Eleatic Lectures, returns to his well-known interpretation of the Eleate as a scientist fully aware of the epistemological foundations of knowledge and capable of foreshadowing the ultimate outcome of the evolution of science. But Cerri also shows us how his reading is supported by the work of two thinkers who grew up in the very bosom of the school of Elea: Zeno, with his arguments against multiplicity, and Leucippus, the originator of atomism. To discuss this interpretation, ten scholars have been called upon, with whom Cerri engages in a dense dialogue in the volume's concluding pages.
