101 Great Philosophers Quotes

“Sextus [Empericus] identifies three different types of philosophy. There are Dogmatists, who think that they know the truth. There are Academic Sceptics, who think the truth can never be known. Then there are Sceptics, who retain an open mind, not thinking truth is yet discovered, but prepared to accept that it might be.”
