What is the true source of knowledge? Is it rationalism, the theory that knowledge comes from intellectual and deductive reasoning? Or by contrast, is it empiricism, the theory that knowledge comes only from sensory experience. Rene Descartes and David Hume are the debutantes of this polarizing subject. Descartes at bat for rationalism, while, Hume takes the mound for empiricism. Both write and reason well, and could easily sway a layman. While juxtaposing the two, however, one becomes more preferable. Custom is the way of life. Descartes’ views are found in his book Meditations on First Philosophy.
