Everyone knows “I think, therefore I am” but after a full read-through of Descartes‘s Meditations in philosophy class, I wanted to know more about his work and life. I am fascinated by his emphasis that we should doubt our sensory views of the world for they are only a semblance of what he believes is the “true form” of the universe: a mathematical one, invisible initially, but eventually graspable by the rational human mind.
