This is the book I had been waiting to read for so long. Mark Matousek writes with such elegance, breath of knowledge & compelling wisdom on one of the key issues of our time. It is challenging & perceptive & I simply could not put it down. I would urge anyone to read it, even those whose personal views & beliefs already provide them with answers to this fundamental question. Much gratitude to the author for writing one of the most important books I have ever read..
