“Pyrrho led a most noble philosophy: to quote Ascanius of Abdera, taking the form of agnosticism and suspension of judgement, he denied that anything was honorable or dishonorable, just or unjust. And so, universally, he held that there is nothing really existent, but custom and convention govern human action; for no single thing is in itself any more this than that. He led a life consistent with this doctrine, going out of his way for nothing, taking no precaution, but facing all risks as they came, whether carts, precipices, dogs or what not, and, generally, leaving nothing to the arbitrament of the senses; but he was kept out of harm's way by his friends who, as Antigonus of Carystus tells us, used to follow close after him.”

“Nausiphanes (Ѻ)(Ѻ) when a young man was captivated by him: at all events he used to say that we should follow Pyrrho in disposition but himself in doctrine; and he would often remark that Epicurus, greatly admiring Pyrrho's way of life, regularly asked him for information about Pyrrho.”

“Whether there exists a god. or whether he exists not, our duties will be the same; and our nature, if consulted, will prove, that vice is an evil, and that virtue is a real and substantial good. We are assured, that there have been found philosophers and atheists, who deny the distinction of vice and virtue, and who have preached up debauchery and licentiousness of manners: in this number, may be reckoned Aristippus and Theodorus, surnamed the Atheist, Bion (Ѻ), the Boristhenite, Pyrrho, etc., amongst the ancients (see: Diogenes Laertius), and amongst the moderns, the author [Bernard Mandeville] of the Fable of the Bees [1705](Ѻ), which, however, could only be intended to show, that in the present constitution of things, vices have identified themselves with nations, and have become necessary to them, in the same manner as strong liquors to those who have habituated themselves to their use. The author who published the Man Automaton [Mettrie, 1748], has reasoned upon morality like a madman.”

“The great subverter of Pyrrhonism or the excessive principles of skepticism is action, and employment, and the occupations of common life.”

— David Hume (c.1775) (Ѻ)
