An Illustrated Brief History of Western Philosophy, ch. 11

One of my favorite philosophers is Descartes. So, I was excited to read this chapter. I was surprised to see this statement: "If you wanted to put Descartes' main ideas on the back of a postcard you would need just two sentences: man is a thinking mind; matter is extension in motion." I am not skilled enough to know if this is true, but it seemed to me dismissive. Regardless, the author expends great care to walk through the history and thought of Descartes as best as you can in the short pages allowed.
