Tim Radford, in his Guardian review, calls the presentation of the physical book "prodigiously illustrated and beautifully designed", and regarding the content says "it is a distillation of so much that Dawkins has written and argued since the publication of The Selfish Gene ... The strength is that he knows his ground. The weakness is that – for a 'family audience' – he deliberately constrains his vocabulary along with the exuberant imagery and belligerence that made his reputation from the start."[9]
