The Enlightenment, as it’s name implies, was a time period in which philisophical questioning of previously accepted principles led to a greater understanding of the world around us. Descartes’ method of proving the existence of reality itself, is fundementally important as it allows us to derrive more complex truths. When descartes states that his ability to think is the universal proof for his own existence, he expounds that truth into a reason for why God must exist as well. Through the discussion of omnipotence and what it means to be flawless, Descartes sets a basis for other enlightenment thinkers to build upon, which is why he is considered one of the fundamental philosiphers of that time period. His statements of universiality progressed through the years alongside the method which he uses to refute opposing thoughts, which is to negate any and all doubts contrary to his own. Descartes’ discourse on method is  there to serves as a handbook not only loaded with predetermined thruths, but also to serve as a guide on how to arrive at a new truths following in his footsteps.
