Breathtaking, brilliant and passionate, the essays, journalism, lectures and letters in this new collection make an unanswerable case for the wonder of scientific discovery and its power to stir the imagination; for the practical necessity of scientific endeavour to society; and for the importance of the scientific way of thinking - particularly in today's "Post-truth" world. More than forty pieces are gathered here, with an introduction and new commentary by the author in dialogue with himself across the years. They range over subjects from evolution and Darwinian natural selection to the role of scientist as prophet, whether science is itself a religion, the probability of alien life in other worlds, and the beauties, cruelties and oddities of earthly life in this one. Alongside the explications, the celebrations and the controversies are wonderfully funny ventures into satire and parody, and moving personal reflections in memory and honour of others. A sparkling showcase for his rapier wit, the clarity, precision and vigour he brings to an argument, the beauty of his prose, the depth of his feeling and his capacity for joy, Science in the Soul is further evidence of Richard Dawkins' status as one of science's all-time great communicators.
