Furthermore, in the meditations, Rene Descartes emphasizes on doubting everything man sees because the devil works to deceive man. But I would like to point out, if man lives under these conditions, and supposing that there is indeed an entity that is out to trick man, man will not have a basis in understanding what is true. I believe man should never cower in fear of the unknown, and if a man does indeed doubt everything for the sole reason that there is an entity out to deceive man rather man should rise from this thinking and think accordingly.When someone is the author of his own thoughts and that author of thoughts is indeed wrong in something. I would like to argue that it is not because a supreme powerful being deceived that author of thoughts rather it is a mistake because of ignorance. The author of thoughts simply did not know what that thing is. It is not because of some supreme powerful deceiver rather the author of thoughts deceived himself because of his lack of knowledge. Mistakes in general happen because of a lack of knowledge.In conclusion, I believe Rene Descartes’ method of doubt is in fact useful only to a certain extent, but anywhere beyond it is downright absurd and a danger to the thinking of man. Certainty cannot emerge from doubt simply because in doubting everything, you also doubt truth as well. And in doubting “truth” or finding the real truth it beats the purpose of using the method of doubt of Rene Descartes. On Mathematics, I believe that Mathematics cannot be used as the central science in the method of doubt simply because it is the only science that conforms to something that is certain. And lastly, the method of doubt does not show any sign of an “answer” or a basis of what is true, rather all it states is to doubt everything until man reaches that very truth. Meaning, man will ultimately continue to doubt everything he senses without a limit. In doing so, if man does indeed doubt without a cause, I see no point in using the method of doubt.
