Having read and enjoyed "Letter to a Christian Nation" by the same author, I was looking forward to "The End of Faith".
I found it dull and hard-going. I have given it several goes and just given up. Life's too short!
The people who really need to read a book like this aren't going to go near it and for the rest of us, there are better books about. "Letter to a Christian Nation" for a start and of course "The God Delusion" by Richard Dawkins, which covers broardly the same stuff and is much more readable.
I really can't begin to articulate or do justice to the quality and lucidity of the arguments put forward by Harris within this book, so I'll just say this;
If you have an open, intelligent and enquiring mind - Read it.
If you want a better understanding of why the world is in such a mess - Read it
If you are interested in ethics, moral identity and politics - Read it.
If you are intrigued by the nature of belief - Read it
