A deep dive into the science of love, from polyamory to our love of pets, this book will change the way we think about ourselves, our relationships and what it means to be human. In this entertaining and accessible exploration of love, Oxford anthropologist Dr Anna Machin dives into the science behind the myriad types of love that exist in the world, including romantic love, parental love, friendships, love for pets, football teams, religious love and even love for our smartphones. Through original research brought to life by interviews and case studies, and encompassing such fascinating areas as polyamorous relationships, parasocial (love for a celebrity) and sacred loves, this book argues that it is time to stop putting romantic love on a pedestal. By exploring the science that illuminates the benefits of all our different close relationships, Dr Anna Machin encourages us to reconsider the importance of love in our own lives, to interrogate our own experiences, and to reconnect with the heart of what it really means to be human.
