Reporting from the cutting edge of scientific discovery, today's visionary thinkers target the greatest roadblocks to innovation.

Few truly new ideas are developed without first abandoning old ones. In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?

The bestselling editor of This Explains Everything brings together 175 of the world's most brilliant minds to tackle Edge.org's 2014 question: What scientific idea has become a relic blocking human progress? Each year, John Brockman, publisher of Edge.org-"The world's smartest website" (The Guardian)-challenges some of the world's greatest scientists, artists, and philosophers to answer a provocative question crucial to our time. In 2014 he asked 175 brilliant minds to ponder: What scientific idea needs to be put aside in order to make room for new ideas to advance? The answers are as surprising as they are illuminating. In : * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Geoffrey West challenges the concept of a "Theory of Everything" * Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Nina Jablonski argues to rid ourselves of the concept of race * Alan Guth rethinks the origins of the universe * Hans Ulrich Obrist warns against glorifying unlimited economic growth * and much more.
