Fascinating text with interesting theories, and not hard to read. Part four definitely the most relevant. Part one and two felt like introduction and five and six like conclusion. However, I had to keep reminding myself that it was published in 1637 to not get angry at the outrageous theories on God and animals. Also, Descartes sounds like a massive megalomaniac. The text serves as a good introduction to the work of Descartes, but I am not sure I will read much more of it. Although his ideas on reason and the Soul are very interesting, religion is a big part of his philosophies, and I have a hard time reading almost scientific language used to prove the existence of a Chistian God, no matter when it was written.
