In discourse five Descartes cleverly speaks of an imaginary world rather than the one we live in. This is a clever way of Descartes avoiding controversy with the church. This imaginary world he claims was created by God as a random chaos of matter. He then goes on to explain that God then induces certain laws of nature that puppet the behavior of this matter, while at the same time leaving this imaginary world he speaks of untouched. Philosphers were quite clever apparently. Or was it that people were just stupid back then? Who knows. He then proceeds by going over the mechanics of nature. Such as the veins and arteries in our bodies, and the blood-flow to our vital organs. Blood, he makes seem, is the essence to life. His explaining paints an almost machine-like picture of the human body. But he does make sure that he clarifies the fact that the body is far greater and more complex than any normal machine man could create. What I found most interesting was the fact that he claimed that all living things go to the same place when we perish, but what separates us from those things is our soul. I believe he came to this conclusion from analyzing the mechanics of the human body.
