Imagine living in the future in a world already damaged by humankind, a world where resources are insufficient to meet everyone's basic needs and where a chaotic climate makes life precarious. Then imagine looking back into the past, back to our own time and assessing the ethics of the early twenty-first century. "e;Ethics for a Broken World"e; imagines how the future might judge us and how living in a time of global environmental degradation might utterly reshape the politics and ethics of the future. This book is presented as a series of history of philosophy lectures given in the future, studying the classic texts from a past age of affluence, our own time. The central ethical questions of our time are shown to look very different from the perspective of a ruined world. The aim of "e;Ethics for a Broken"e; World is to look at our present with the benefit of hindsight - to reimagine contemporary philosophy in an historical context - and to highlight the contingency of our own moral and political ideals.
