Abstract
Our times seem to be afflicted by scepticism. But what form of skepticism is it the one that truly affects us, and how have we inherited this legacy from ancient thought? This work explores the contemporary & nacute;se of the so-called post-truth, fake news, and other concerning phenomena from an epistemological standpoint. It delves into the historical influence of philosophical scepticism in its two main variants: Pyrrhonism and Academic skepticism. Special attention is paid to the relationship that each of these schools had with the infallibilist thesis, their revival during the Renaissance, and their influence through Descartes to the present day. Finally, it is claimed that it is the infallibilist interpretation of scepticism, as well as its disconnection from any practical motivation, rather than scepticismper se, to which these harmful effects should be attributed.
