Descartes considers the things that one seems to know for certain by reason – for example, mathematical claims, like 2+2=4. When contemplating the ways one could be mistaken about this, he proposes that there might be a powerful demon who can trick one into perceiving 2+2=4 as an undeniable truth when in fact, it is not. Descartes allows this as a real possibility and thinks of all such knowledge as doubtable too.
