ABSTRACT
The Meditations on First Philosophy is one of Rene Descartes's most popular works. In Meditation I he attempts to prove that minimum epistemological assumptions require only to accept indubitable logical processes of thinking and that all else is subjected to radical doubt. In Meditation II he argues that whether or not there is a Great Deceiver, the subject can be certain of his own existence. The second key argument of Meditation II concerns Descartes's theory of dualism in which his analysis of candle wax leads him to conclude that bodies are better known by the understanding than by the senses. In Meditation I, Descartes talks about constructing a sound building, which is a metaphor for his knowledge. In Argument One of Meditation II, Descartes suggests that thinking about one's own thinking proves that there is a subject doing the thinking.
