Minds are complex artifacts, partly biological and partly social; only a unified, multidisciplinary approach will yield a realistic theory of how they came into existence and how they work. One of the foremost workers in this multidisciplinary field is Daniel Dennett. This book brings together his essays on the philosphy of mind, artificial intelligence, and cognitive ethology that appeared in inaccessible journals from 1984 to 1996. Highlights include "Can Machines Think?," "The Unimagined Preposterousness of Zombies," "Artificial Life as Philosophy," and "Animal Consciousness: What Matters and Why." Collected in a single volume, the essays are now available to a wider audience.
