Peri tou me ontos e peri physeos

The work Peri tou mē ontos ē peri physeōs (On That Which Is Not, or On Nature) is attributed to the Greek Sophist Gorgias of Leontini. In this treatise, Gorgias applied the logical methods of the Eleatic school to argue for a nihilistic position, essentially the opposite of Eleaticism's focus on Being. He presented three main points: first, that nothing exists; second, that if anything does exist, it is incomprehensible; and third, that if it exists and is comprehensible, it cannot be communicated to others. This work is seen as a critique of the philosophical tradition that sought to define reality and Being, and it contributed to the decline of Eleaticism by demonstrating the potential for logical arguments to undermine fundamental philosophical tenets.123
