Aristotle’s works on politics, ethics, and metaphysics have made him one of the most widely read of the Greek philosophers. The title of this book, "On the Soul", is a signal to the reader that the topic is critical to understanding humans.
"On the Soul" exists as Aristotle´s personal discourse on what the soul truly is. He begins the text stating that "knowledge of any kind is a thing to be honoured and prized." Therefore, he admits that knowledge on the soul is priceless. His discussion acknowledges that he is only offering his ideology on what the soul is, which is not what all may believe it to be.
