What it is
Skepticism asks: can we be certain of anything? For almost every claim, the skeptic notes, one can find an opposing argument just as strong. Instead of taking a side, the skeptic proposes suspending judgment, neither affirming nor denying. This does not mean giving up on life: the skeptic follows custom and everyday appearances, and believes that letting go of the craving for certainty brings peace of mind.
Pyrrho of Elis, in the fourth century BC, is regarded as the founder of ancient skepticism, later set down in writing by Sextus Empiricus. In the Renaissance, Montaigne revived doubt in his Essays, asking 'what do I know?'. In Argentina, Jorge Luis Borges explored the limits of knowledge in stories and essays. In Brazil, Oswaldo Porchat developed a neo-Pyrrhonism that accepts ordinary life without dogmas. The tradition remains alive in debates about what we really know.
