30 Phil, Chapter 10, Pyrrho of Elis, Touchstone 28: Skepticism.
Skepticism emphasizes the continuous challenging of beliefs. Pyrrhonian Skepticism, founded by Pyrrho of Elis, takes this a step further by encouraging you to suspend judgment about reality and truth. This approach urges you to question your beliefs and avoid dogmatism. With skepticism, you question both reason and sensory data. Pyrrhonian Skepticism asserts that neither reason nor sensory perception can provide us with certain knowledge, leading to the suspension of judgment on all things.
