Lose yourself in the vast sewer networks that lie beneath the world's great cities - past and present. Let detailed archival plans, maps and photographs guide you through these subterranean labyrinths - previously accessible only to their builders, engineers and, perhaps, the odd rogue explorer. This execrable exploration traces the evolution of waste management from the ingenious infra-structures of the ancient world to the seeping cesspits and festering open sewers of the medieval period. It investigates and celebrates the work of the civil engineers whose pioneering integrated sewer systems brought to a close the devastating cholera epidemics of the mid-19th century and continue to serve a vastly increased population today. And let's not forget those giant fatbergs clogging our underground arteries, or the storm-surge super-structures of tomorrow.

'If we hope to meet the moral test of our times, then I think we're going to have to talk more about the "empathy deficit". The ability to put ourselves in somebody else's shoes, to see the world through somebody else's eyes . . .' Barack Obama Empathy is the power of understanding others, imaginatively entering into their feelings. It is a fundamental human attribute, without which mutually co-operative societies cannot function. In a revolutionary development, we now know who has it, who lacks it and why. Via the MRI scanner we are mapping the human brain. This is a new frontier that reveals a host of beneficial ideas for childcare, teens challenged by the internet, the justice system, decent healthcare, tackling racism and resolving conflicts. In this wide-ranging and accessible book full of entertaining stories that are underlined by the latest scientific research, Peter Bazalgette also mounts a passionate defence of arts and popular culture as a means of bridging the empathy gap. As the world's population expands, consuming the planet's finite resources, as people haunted by poverty and war are on the move and as digital communications infinitely complicate our social interactions, we find our patience and our sympathy constantly challenged. Here is the antidote. Culminating in a passionate manifesto on empathy, The Empathy Instinct is what makes us human and what can make us better humans.
