Descartes then presents a further thought experiment, sometimes known as the evil demon argument, which brings even knowledge of mathematics and geometry in to question descartes starts by asking whether it is possible that he is being deceived by god even about things which seem universally true, such as the belief that 2 + 3 = 5. The evil demon is a thought experiment devised by descartes in the first meditation to buoy up the extremely strong doubt that gets his meditations off the ground.

Descartes was concerned with providing arguments against skepticism, which is the view that we do not have knowledge skeptics argue that either we don't actually know (justified true belief) the things that we think we. Descartes proposes a very similar thought experiment he asks the reader to imagine that there is a deceiving demon that is creating an illusion of the world, casting doubt on everything except the essence of the human being and soul, the self-awareness which descartes believes proves that you must exist.
