In this episode of 8-Bit Philosophy, Cartesian doubt is explained with a little help from Castlevania. How does “What if an evil wizard is incepting ideas in my head?” lead Descartes to believe “I think, there I am?”

Rene Descartes was a French philosopher. His famous phrase “I think, therefore I am” appears in Latin in his work “Principles of Philosophy.”

8-Bit Philosophy is a new YouTube series that tackles philosophical concepts with video games. It’s made from the same people that created Thug Notes, a YouTube series on literature.
