Unethical book
Format: Paperback
Had to get this book for a required class. This book is unreadable. It is written in an outdated language of old philosophers. The book itself if unethical. It starts out with one inch margins then once you get into it they switch to half inch margins. That's deceitful. Everyone I have talked to in the class can't stand the book. l read it because I have to, but I'm not getting anything out of it. Humanity is certainly lacking ethics these days, but this book is a waste of my time and if I'm struggling reading it, I doubt anyone who actually needs to read this book will make it through more than a page.
