This book sets out a new kind of “post-materialist” philosophy taking hold among younger generations, one that will have a beneficial impact on the earth’s natural and human environment. Philosophers usually stick to conceptual ideas without much attention to the messy details of worldly reality, ideas that are wonderful in themselves, but in need of confrontation with the actualities of natural and human history. In drawing the link between philosophy and the real world, the author directs special attention to values we hold toward the natural environment and concerns about the global problem of climatic warming. Philosophy, we sill see, can inform us not just about deciding how we should live, but about how our values influence future prospects for the natural world from which we gain sustenance and spiritual inspiration.
