The Evil Demon Argument states that an evil demon has the will, power, and the knowledge to make a person a constant victim of deception. Even one is thinking something is self-evidently true, it’s not.

He pushes skepticism to its limits by introducing the notion of an “evil demon”, a being that always tricks us into believing true what is actually false. The only certainty that Descartes can find is that nothing is certain. Knowledge acquired through the senses was called into doubt by argument from dreaming and knowledge acquired through intellect was called into
