Decartes' Meditations 1 and 2

In Decartes’ meditations the meditator reflects on his thoughts. The meditator thinks about where his thoughts have come from and if the origins of these thoughts are reliable or if they have been all based on false ideas. With this doubt building up inside, the meditator attempts to build his ideas from the ground up. In meditation 1 the meditator is considering all things that can be called into doubt. He reflects on all his thoughts and realizes they all can be called into doubt and therefore starts arguing these points. In meditation 2, the mediator takes what he has learned from mediation 1 and keeps on building his beliefs. He states that there is one thing he knows for certain and that is that “I exist.” return, calls all other things into doubt. He first asks himself “what can I know for certain?” Once this question is answered, this will be his foundation for a whole new set of beliefs. The meditator’s first argument is the argument of illusion. He states that everything he knows he has learned from his senses. The senses for the meditator, and most people, have deceived before whether it is smelling something that really isn’t what you think it is, or seeing something far away and getting closer and it is not what you thought it was. The meditator thinks that if his senses have deceived him once, then they could be fooling him all the time. After simmering the thought, he concludes that his senses only deceive him when it comes to small or far away objects. The meditator then brings in the fact that insane people have these deceiving moments a lot which makes them considered insane. Insane people have very wildly insane beliefs about large present matters. Then it is as if the meditator has a feeling that if his senses deceive him like that, then maybe he could be insane which concludes all your beliefs are subject to doubt. However, after contemplating this argument of illusion and insanity, Decartes dismisses it because it is insane. I disagree with
