Pyrrho (360-270 BC), Greek credited as the first skeptic philosopher and inspiration for the school known as Pyrrhonism, founded by Aenesidemus in the 1st century BC. Pyrrho wrote nothing. His ideas are known mainly through Outlines of Pyrrhonism by the Greek physician Sextus Empiricus. According to Pyrrho the proper course of the sage is to ask himself 3 questions. Firstly we must ask what things are and how they are constituted. Secondly, we ask how we are related to these things. Thirdly, we ask what ought to be our attitude towards them. Pyrrho's answer was that things are indistinguishable, unmeasurable, undecidable, and no more this than that, or both this and that and neither this nor that. He concluded that human senses neither transmit truths nor lie. Humanity cannot know the inner substance of things, only how things appear.
