I Is an Other

The New York Times bestselling author examines how metaphors influence every aspect of our lives, from art to medicine, psychology to the stock market.Metaphor is much more than a mere literary device. Often hiding in plain sight, it is a critical aspect of how humans think and communicate. Metaphor is at work in all fields of human endeavor, including economics, business, science, and psychology.In I Is an Other, James Geary takes readers from Aristotle's investigation of metaphor right up to the latest neuroscientific insights into how metaphor works in the brain. Along the way, he demonstrates how metaphor affects financial decision making, creates effective advertising, and helps us achieve emotional insight and psychological change. Geary also explores how a life without metaphor, as experienced by some people with autism spectrum disorders, significantly changes the way a person interacts with the world.
