Description
A philosopher calls for a revolution in ethics, suggesting we expand our “moral circle” to include insects, AI systems and even microbes
Today, human exceptionalism is the norm. Despite occasional nods to animal welfare, we prioritise humanity, often neglecting the welfare of a vast number of beings. As a result, we use hundreds of billions of vertebrates and trillions of invertebrates every year for a variety of purposes, often unnecessarily. We also plan to use animals, AI systems and other non-humans at even higher levels in the future. Yet as the dominant species, humanity has a responsibility to ask: Which non-humans matter, how much do they matter and what do we owe them in a world reshaped by human activity and technology?
In The Moral Circle, philosopher Jeff Sebo challenges us to include all potentially significant beings in our moral community, with transformative implications for our lives and societies.
This book explores provocative case studies such as lawsuits over captive elephants and debates over factory-farmed insects, and compels us to consider future ethical quandaries, such as whether to send microbes to new planets and whether to create virtual worlds filled with digital minds. Taking an expansive view of human responsibility, Sebo argues that building a positive future requires the shedding of human exceptionalism and radically rethinking our place in the world.
Reviews
"In The Moral Circle, Jeff Sebo defends, with engaging examples and plausible arguments, a disturbing conclusion: that the expansion of the moral circle beyond our own species, for which I have argued, does not go nearly far enough. I expect this book to trigger an important debate." — Peter Singer, author of Animal Liberation and Animal Liberation Now
"Does what happen to an insect, a plant, or a robot, matter to them? Compelling thought experiments make The Moral Circle a fascinating read." — Barbara J. King, author of Animals' Best Friends and How Animals Grieve
"In The Moral Circle Jeff Sebo shows us how complicated—and disconcerting—things get when we consider what that moral circle would include—and whether we can really justify leaving any living thing outside the boundaries of our moral concern." — Carl Safina, author of Beyond Words and Alfie and Me
