In Which Future?, David Greene synthesizes principles from evolutionary biology, linguistics, systems engineering, philosophy and political science to argue that if we want any future at all, we don't really have a choice: we must embrace a radical shift in the way we engage with the world and with other human beings. A thoughtful, provocative and important book.

David Greene's powerful insight is in showing how the relationships of humans to nature, and humans to other humans, are deeply interconnected, as well as what this implies. We cannot restore our relationship to the natural world if we do not simultaneously restore our relationships with one another, and our commitment to justice and human flourishing. Which Future?, aptly described as a work of moral philosophy, offers us a wake-up call well worth heeding.

In Which Future?, David Greene draws on principles of cognitive science, evolution, and general systems theory to derive a small set of fundamental moral imperatives. This constitutes an insightful and important new approach to moral philosophy, challenging current neoliberal dogma and speaking directly to central issues confronting humanity. A timely and well-written call to action for us all.

I must have read a thousand times someone saying that we need to revise our way of thinking if we're going to avoid climate and human catastrophe. But such comments are always light on just how we should do that. In Which Future?, Greene fills that gap with a compelling prescription for philosophical and political change.
