René Descartes, often called the father of modern philosophy,
attempted to break with the philosophical traditions of his day and
start philosophy anew. Rejecting the Aristotelian philosophy of the
schools, the authority of tradition and the authority of the senses,
he built a philosophical system that included a method of inquiry, a
metaphysics, a mechanistic physics and biology, and an account of human
psychology intended to ground an ethics. Descartes was also important
as one of the founders of the new analytic geometry, which combines
geometry and algebra, and whose certainty provided a kind of model for
the rest of his philosophy.
The Meditations begins with a series of arguments intended
to cast doubt upon everything formerly believed, and culminating in
the hypothesis of an all-deceiving evil genius, a device to keep former
beliefs from returning [this is the topic of Meditation
1]. The rebuilding of the world begins with the discovery
of the self through the ‘Cogito Argument’ (‘I am thinking,
therefore I exist’) – a self known only as a thinking thing,
and known independently of the senses [this is the topic
of Meditation 2]. The project, then, is to build the entire
world from the thinking self. It is important here that it is not just
the mind that is the foundation, but my mind. In this way,
the starting place of philosophy for Descartes was connected with the
rejection of authority that is central to the Cartesian philosophy.
In beginning with the Cogito, we build a philosophy detached from history
and tradition.
