Peter Singer is often described as the world’s most influential philosopher. He is also one of its most controversial. He helped launch the animal rights and effective altruism movements and contributed to the development of bioethics. 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. We invite you for what promises to be a lively and wide-ranging conversation between two renowned scholars who are both deeply engaged in the public sphere.

In this new book of brief essays, Singer 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. Singer asks whether chimpanzees are people, smoking should be outlawed, or consensual sex between adult siblings should be decriminalized, and he reiterates his case against the idea that all human life is sacred, applying his arguments to some recent cases in the news. In addition, he explores, in an easily accessible form, some of the deepest philosophical questions, such as whether anything really matters and what is the value of the pale blue dot that is our planet. The collection also includes some more personal reflections, like Singer’s thoughts on one of his favorite activities, surfing, and an unusual suggestion for starting a family conversation over a holiday feast.
