'He has admirably attempted to make this as entertaining and easy to read as possible. Indeed, the book's great strength is the lucidity of its exposition of the science of human emotion. Further, Medina peppers the text with some quite fascinating examples of seminal research concerning human behaviour ... Medina's prose is energetic and enthusiastic ...' Canberra Times '... a rich introduction to the current state of the art in understanding the interplay of genes, hormones, synapses and neurotransmitters, which somehow link brains and behaviours ... a cleverly constructed account of some of the most difficult problems of contemporary biology ... welcome additions to the popular literature.' Jon Turney, Times Higher Education Supplement 'Lust, gluttony, avarice, sloth, wrath, envy and pride: Medina successfully uses these sins from Dante's Purgatorio as a vehicle to introduce those genes and their products that influence human behaviours ... Everyone should read the conclusion - in private, unless you enjoy laughing in public.' Hugh Fletcher, The Biologist 'A book to be read by the non-scientist who wants an in-depth view into the workings of genetics, John Medina is clearly an author to do this job. ... the book is a must for philosophers who still get the creeps when they discuss genetics.' Pierre Mallia, Medicine, Health Care and Philosophy, A European Journal
