My rating 3 out of 5.
As you flip through the chapters, it makes a very disturbing read. Provides various thought experiments, changing their circumstances and hence how the conclusions go through a change. Some of these experiments are painful and make us dwell could this angle change the entire meaning so much!
In all, he challenges us to question our beliefs and look at a case from different angles of morality. A question that comes throughout the book- Would you know this would be true, would that change anything in your behavior.
However, it seems through this book we are having the reader challenge their own beliefs to adopt their own. Here is the problem with that- the book is supposed to offer guidelines and not thrust you into a scenario to force some other beliefs. I had hopes that this book is about exploring, it sounded more like preaching to me.
