Starting from the view that to philosophise is to doubt, this paper compares Montaigne's scepticism to ancient scepticism. On the one hand, it is shown that elements from ancient scepticism are used by Montaigne, such as the division of philosophy in three sects and the sceptical principle of opposition. On the other, the paper focuses on the novelties introduced by Montaigne into these sceptical elements. Finally, it is investigated to what extent Montaigne's project of a self-portrait allows him to develop a new kind of doubt.
