Pyrron of Elis is the ultimate representative of skepticism in ancient times. Although it is possible to identify skeptical traits among the sophists and in the school of Megara, it was Pirron who adopted skepticism as a definitive stance. It is estimated that his was a reaction against the dogmatism of other philosophical schools: if philosophy originates from the search, the dogmatic philosopher then considers that he has found the truth, while the skeptic chooses to remain with the search and affirms that it is impossible to find a definitive truth. Their inquiry consists in trying to permanently destroy the arguments of dogmatists.
According to Pirrón all our perceptions are relative since they only depict reality as they “appear” filtered by our senses.
Pirrón therefore derives from an ethics of impertubability: as we do not know with certainty, everything must be indifferent to us, and no opinion has to disturb our spirits. It should be noted that in different ways, Pirrón approaches an ethic similar to stoic, although it has a dogmatic basis. Pirronism has a clear moral intent and tries to respond to the same problems as stoicism and epicureism. It could be said that Pirron's claim is that only a skeptic can aspire to happiness as long as and as he can abstract himself from the anguish of life.
