Descartes Meditations Argument

One of Descartes’ main goals for writing his Meditations is to establish a foundation for knowledge. He calls everything he knows into doubt, in order to find this foundation. The mechanism he uses to establish universal doubt is the assumption of the existence of an evil demon that deceives him of everything. In order to know anything, he must create a foundation based on something he can know for certain. For his foundation, he provides an argument for his own existence. I will argue that Descartes does not provide a good argument because he commits an informal fallacy in the form of begging the question. In Descartes’ First Meditation, he attempts to establish a foundation on which knowledge can be based. He was looking for a solid foundation, …show more content…

In his argument, Descartes is attributing properties to something. In this case, the property is thinking. For something to have properties, you assume that it is a subject. It is also assumed that all subjects exist. In order to describe something with properties, you have to assume that it exists. For example, you can describe a unicorn as something that looks like a horse and has horns on its head. It is known that unicorns don’t exist, so the properties that are given are meaningless. The same thing applies to Descartes. By giving himself the property to think, he is assuming that he exists in the premise so the property is not meaningless. He then argues that based on this property, he must exist. Therefore, premise two, the fact that he is thinking, can only be true if the conclusion, that he exists, is true, forming the informal fallacy. This flaw in the subargument makes the entire argument for his existence faulty, and therefore has not successfully found a foundation for
