The paper discusses the parallels between late Heidegger's view of the world as a fourfold unity of earth, heavens, the divine and the mortal (the Geviert), and a passage in Plato's Gorgias (507e–508a) where the world (kosmos) is conceived of in a similar way. It is argued, first, that the Gorgias passage is not an isolated remark but rather a point where a number of important Platonic insights come together, and second, that Heidegger was well acquainted with these insights and (...) pointed out their ontological significance on various occasions.
