Approaching the thought of Sextus Empiricus (Greek writer of the second century AD), we touch a strange philosophical substance that offers the solution in "epoche" (That is to say the suspension of judgment); However, how should be the suspension of judgment? You have from the philosopher Pyrrho to think about the practice -and only theoretically more skepticism.
In "Sketches pyrrhoniennes" Sextus Empiricus and responds -at invalid Passage- other philosophical schools criticizing according to skeptical manner.
As a discovery that thought was quite complex but so surprising and original.
