Have you ever looked at yourself and your surroundings and wonder if it is all just a dream? Or if you even exist? Well, there is no need to waste your precious time philosophizing, Rene Descartes have already proven this. Through his technique of methodological doubt, Descartes proved that our minds and our bodies do exist because we are “thinking things”. Methodological doubt required Descartes to doubt everything until he found something that was impossible to doubt. He started off with doubting our physical senses, which we trust and use to make certain that something is true and certain. As Descartes said, “it is sometimes proved to me that these senses are deceptive”, for we do experience illusions and dreams in which we believe we are doing something …show more content…
