Lao Tzu was a philosopher of ancient China, best known as the author of the Tao Te Ching. His association with the Tào Té Chīng has led him to be traditionally considered the founder of philosophical Taoism (pronounced as "Daoism"). He is also revered as a deity in most religious forms of Taoist philosophy, which often refers to Laozi as Taishang Laojun, or "One of the Three Pure Ones".
Gorgias (Greek: Γοργίας, c. 485 – c. 380 BC), called "the Nihilist," was a Greek sophist, Italiote, pre-Socratic philosopher and rhetorician who was a native of Leontini in Sicily. Along with Protagoras, he forms the first generation of Sophists.
