What does it mean to be human? And what, if anything, does it have to do with being a member of the animal species Homo sapiens? This dazzling book gets to the very heart of our rather unscientific motivations and prejudices, showing how they are of great use in resolving the world's biggest problems. From beasts to aliens, this book explores widely discussed but often problematic links between humans and six other beings, tackling deep philosophical questions including humanity's common purpose, life's meaning, and what it means to be accepted as part of a community. Global in its outlook and illustrated with stunning pictures, Human is a powerful, funny, and iconoclastic antidote to post-humanism.
