Derek Parfit (1942–2017) is the most famous philosopher most people have never heard of. Widely regarded as one of the greatest moral thinkers of the past hundred years, Parfit was anything but a public intellectual. Yet his ideas have shaped the way philosophers think about things that affect us all: equality, altruism, what we owe to future generations, and even what it means to be a person. In Parfit, David Edmonds presents the first biography of an intriguing, obsessive, and eccentric genius.

A train is racing toward five men, tied to the track. Unless the train is stopped, it will inevitably kill all five men. If a fat man is pushed onto the line, although he will die, his body will stop the train, saving five lives. Would you kill the fat man? As David Edmonds shows, answering the question is far more complex, and important, than it first appears. In fact, how we answer it tells us a great deal about right and wrong.

Peter Singer is often described as the world's most influential philosopher. Now, in Ethics in the Real World, Singer shows that he is also a master at dissecting important current events in a few hundred words. In this book of brief essays, he applies his controversial ways of thinking to issues like climate change, extreme poverty, animals, abortion, euthanasia, human genetic selection, sports doping, the sale of kidneys, the ethics of high-priced art, and ways of increasing happiness.

The world-renowned philosopher and author of the best-selling Justice explores the central question of our time: What has become of the common good? World-renowned philosopher Michael J. Sandel argues that to overcome the crises that are upending our world, we must rethink the attitudes toward success and failure that have accompanied globalization and rising inequality. Sandel shows the hubris a meritocracy generates among the winners and the harsh judgment it imposes on those left behind, and traces the dire consequences across a wide swath of American life.

Since its original publication in 1975, Animal Liberation has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. Now, for the first time since its original publication, Singer returns to the major arguments and examples and brings us to the current moment.

E. H. Gombrich's world history, an international best seller now available in English for the first time, is a text dominated not by dates and facts but by the sweep of experience across the centuries, a guide to humanity's achievements, and an acute witness to its frailties.

Humanism is an expansive tradition of thought that places shared humanity, cultural vibrancy, and moral responsibility at the center of our lives. For centuries, this worldview has inspired people to make their choices by principles of freethinking, intellectual inquiry, fellow feeling, and optimism. In this sweeping new history, Sarah Bakewell, herself a lifelong humanist, illuminates the very personal, individual, and, well, human matter of humanism and takes listeners on a grand intellectual adventure.

Ruth Ben-Ghiat is the expert on the "strongman" playbook employed by authoritarian demagogues from Mussolini to Putin. In Strongmen, she lays bare the blueprint these leaders have followed over the past 100 years, and empowers us to recognize, resist, and prevent their disastrous rule in the future.

In The Righteous Mind, social psychologist Jonathan Haidt explores the origins of our divisions and points the way forward to mutual understanding. His starting point is moral intuition - the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right.

Superintelligence asks the questions: What happens when machines surpass humans in general intelligence? Will artificial agents save or destroy us? Nick Bostrom lays the foundation for understanding the future of humanity and intelligent life. The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. If machine brains surpassed human brains in general intelligence, then this new superintelligence could become extremely powerful - possibly beyond our control.

Originalism, the view that the meaning of a constitutional provision is fixed when it is adopted, was once the fringe theory of a few extremely conservative legal scholars but is now a well-accepted mode of constitutional interpretation. Noted legal scholar Erwin Chemerinsky gives a comprehensive analysis of the problems that make originalism unworkable as a method of constitutional interpretation. He argues that the framers themselves never intended constitutional interpretation to be inflexible and shows how it is often impossible to know the "original intent" of any provision.

From dolphins to crows, elephants to octopuses, Nussbaum examines the entire animal kingdom, showcasing the lives of animals with wonder, awe, and compassion to understand how we can create a world in which human beings are truly friends of animals, not exploiters or users. All animals should have a shot at flourishing in their own way. Humans have a collective duty to face and solve animal harm. An urgent call to action and a manual for change, Nussbaum’s groundbreaking theory directs politics and law to help us meet our ethical responsibilities as no book has done before.

Totalitarianism is not a coincidence and does not form in a vacuum. It arises from a collective psychosis that has followed a predictable script throughout history. In The Psychology of Totalitarianism, world-renowned Professor of Clinical Psychology Mattias Desmet deconstructs the societal conditions that allow this collective psychosis to take hold. By looking at our current situation and identifying the phenomenon of “mass formation”—a type of collective hypnosis—he clearly illustrates how close we are to surrendering to totalitarian regimes.

In the popular imagination, superhuman artificial intelligence is an approaching tidal wave that threatens not just jobs and human relationships, but civilization itself. Conflict between humans and machines is seen as inevitable and its outcome all too predictable. In this groundbreaking audiobook, distinguished AI researcher Stuart Russell argues that this scenario can be avoided, but only if we rethink AI from the ground up. Russell begins by exploring the idea of intelligence in humans and in machines.

Although Roe v. Wade identified abortion as a constitutional right 45 years ago, it still bears stigma - a proverbial scarlet A. In public discussion, both proponents and opponents of abortion's legality tend to focus on extraordinary cases. This tendency keeps the national debate polarized and contentious. Professor Katie Watson focuses instead on the cases that happen the most, which she calls "ordinary abortion". Scarlet A gives the reflective listener a more accurate impression of what the majority of American abortion practice really looks like.
