Taking another look at this book
Format: Paperback
I am revising my review in fairness to the author. I purchased this book on the secondary market. For my initial review I had not read the book cover to cover. This book features an anthology of philosophical excerpts and writings on different topics concerning contemporary issues in ethics. The author prefaces each topic section with an overview of the pertinent legal, historical and social developments. This is followed by contributions on the subject from different philosophical viewpoints. Some of these contributions can be rather turgid, others easily digestible. As a whole, I find the book to offer good coverage of the topics. The book addresses many ethical issues with a fair degree of contemporaneous coverage but more ethical questions of seminal import are required. For instance, perhaps there ought to be other topics introduced for future revisions that are more poignant to life in the national security state, such as the ethics of social vigilance in response to domestic government spying, the abrogation of habeas corpus and war crimes such as droning and torture. These are serious ethical conundrums in our society that deserve consideration in any philosophy course focusing on contemporary issues in ethics.
Having a more comprehensive reading of this book I have significantly upgraded my appreciation of its coverage and the work that went into it and I would recommend it to professors looking to introduce ethics studies in a philosophy curriculum.

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 It is written in an outdated language of old philosophers.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.
