Pyrrho

Pyrrho (c. 360 B.C.E. - c. 275 B.C.E.), a Greek philosopher from Elis, was credited in antiquity as being the first skeptic philosopher and the inspiration for the school known as Pyrrhonism. His followers adopted the label &quot;zetetic&quot; (Greek meaning &quot;seeker&quot;) and stressed the importance of observation and personal experience as a path to truth claiming that man can only know the world as it appears to him. This approach had a heavy influence on members of the Flat Earth movement of the 19th Century, many of whom adopted the label for themselves, forming the Universal Zetetic Society.
