Beginning with the very origins of life on Earth, Woolfson considers prehistoric human-animal interaction and traces the millennia-long evolution of conceptions of the soul and conscience in relation to the animal kingdom, and the consequences of our belief in human superiority. She explores our representation of animals in art, our consumption of them for food, our experiments on them for science, and our willingness to slaughter them for sport and fashion, as well as examining concepts of love and ownership.

Drawing on philosophy and theology, art and history, as well as her own experience of living with animals and coming to know, love, and respect them as individuals, Woolfson examines some of the most complex ethical issues surrounding our treatment of animals and argues passionately and persuasively for a more humble, more humane, relationship with the creatures who share our world.
