Skepticism is a philosophical point of view and a skeptic is one who is expressing skepticism.


The two major schools of skepticism in Greek philosophy are the Academic and the Pyrrhonian.[1]

  • Academic: Named after Plato's Academy, the The philosophy that nothing can be known for certain
  • Pyrrhonian: Named after the Greek, Pyrrho of Elis (c. 360-275 B.C), it is the point of view of suspended judgement. The Greek, Aenesidemus (c. 100-40 B.C.), formulated it into a philosophy and adopted the title of "skeptic" (from skeptikos, meaning "inquirer") and "doubters"; (from ephektikos, meaning "one who suspends judgment")[1]
