Archimedes point for knowledge

Archimedes sought “one firm and immovable point in order to shift the entire earth”. The idea is that given this immovable point and a long enough lever he could move anything. The narrator claims that equally great things may be achieved in the realm of knowledge if he is able to find a similar firm and immovable point. Following the First Meditation it seems that there is nothing left to be used as this point. However, the Second Mediation lays out the cogito reasoning. He realizes that no matter how much of a deceiver his malignant demon is, he is still having thoughts that are deceived. Although there may be no senses or body, as long as there is thought of these things there has to be existence. This notion of “I think, therefore I am” is to the narrator necessarily true. One’s existence is a necessity as long as he or she is thinking. This necessity is the certainty the narrator was seeking. The narrator finds no in way this reasoning could be false, which lends it to be the firm and immovable point he can achieve great things through. Now that he has his Archimedes point he can build upon it a host of knowledge. He begins to do this as he considers the wax and how he relates to it through the senses. He realizes that the senses ultimately reduce to the intellectual. In this way, the senses are built off of thought and his immovable point. So long as he has the cogito reasoning as a certainty for the foundation of his knowledge he does not have to fear the collapse of the knowledge he builds upon it.
