why is it so basic? It's effectively an introductory text. He just says "humans are this way" but I'm way more interested in the explanation for exactly WHY humans are that way and the proof that goes along with it. There is no deeper insight here, its a mile wide and an inch deep.
If this is your first time delving into this topic then I'd recommend as an overview, but if you were looking for something with deeper, fundamental insights into the WHY, skip this.
