This book shows you what it is like to think along with Aristotle and helps you to see the universe and our place in it as he thought they they had to be seen to be scientifically intelligible. As a portrait is composed of colors and shapes that collectively represent someone, so Aristotle's works are composed of arguments that collectively represent the causal structure of the universe, from the stones, plants, and animals around us to the starry heavens above and the god beyond them. The aim of this brief immersion is to guide you through those arguments in a way that lets you understand for yourself why they proceed as they do and end where they do.
