This book provides an overview of imagination and its role for survival in a complex, high-intensity environment. More than this, this book aims, ambitiously, to inspire imagination. It establishes that imagination is neither abstract nor frivolous, but a technique, a skill, and a discipline that one must embrace to facilitate the transformation of both society and oneself. Whether facing contemporary challenges like climate change, social and political crises, or grappling with the complexities posed by artificial intelligence, machine learning, or transhumanism, imagination seems to be what is lacking in order both to endure and to build. Often reduced to the realm of artists, imagination is a unique value added by humankind, one that can envision a way of creating new worlds. In this book, the imagination becomes a spiritual exercise aimed at rethinking our ways of life in order to establish both a new construction of oneself and society. Researchers and general readers alike will find much in this call to imagine how other worlds might be possible.
