What is the author's style in The Politics of Aristotle by Aristotle?

This book is written in an predominantly objective manner. The author writes about the world closest to where he lives and, as a result, the work has a touch of the journalistic sense about it. He writes in the third person. The author of the book had decades of experience living as a foreigner in the city-state of Athens. The author recognized that the city-states were a somewhat loose association of independent and interdependent set within Grecian culture. The author's own homeland was similarly divided early on in his life. That is, while Macedon had some regional and cultural features that united it, there were multiple kings operating within that region. As such, the area was not united under a higher political order.
