Rene Descartes was born in 1596. At the age of 10, he began school at College Henri IV. Descartes received a classical education at College Henri IV and learned many subjects, including math, at the Jesuit institution.

Descartes never served combat, but he did have a life changing moment while in the army. While meditating about the uncertainty and disunity of knowledge, he had an epiphany about how he could make knowledge more certain and unified, such as mathematics. After a period of not focusing on how to make his idea a reality, he finally sat down and focused after receiving encouragement from Cardinal de Berulle.

After many questions and comments on Part IV he wrote “Meditations in First Philosophy” to expand on his ideas in 1640. “Meditations” was a very controversial book and made a lot of people outraged.

The res extensa is divisible and has numerous parts. It is also goes down in a downward motion. The body is dependent on many things such as food and water. The body needs the brain to connect all of its parts. “…the senses thus act to preserve and maintain the body.” The body also needs the senses to alert when it is hungry, when its throat is dry, or when something is too hot or cold. Although, senses may be deceptive there are around to protect the body.
