Furthermore, Descartes took his search for the truth that is beyond any doubt to the extreme by imagining that there is an ‘evil genius’. Descartes consider the evil genius to be someone who has the power of God, but who is not good. The ‘evil genius’ is determined to deceive us into thinking that there is a physical world when in fact there is none. For example, using the famous Matrix movie, the machines that are used in the movie would be considered as the ‘evil geniuses’. Everything would seem to us to be real just like in the matrix, but none of it would be real. However, Descartes does not actually believe that this ‘evil genius’ exists, but there is no way to ruled it out based on our sensory experience. Hence, how can we doubt that one plus two does not equals three when our minds necessarily admit that it equals three? Descartes used the concept of the ‘evil genuis’ to hypothesize that maybe there is an ‘evil god’ who is deceiving us from getting the correct answer. Even though, we always think that one plus two equals three. Maybe this god is actually tricking us, and in reality it equals four. Descartes linked this circumstance where we are absolutely confident about our belief toward a certain fact, but despite this confident we often discover later that we had mistaken about the fact. This might be the case for our mathematical truths in which an ‘evil god’ is deceiving us from getting the correct solution to a problem every time we count or do the mathematics.
