The roots of the post-truth, alternative facts present can be discovered in America’s “promiscuous devotion to the untrue” and its instinct to believe in make believe, evident across four centuries of magical thinkers and true believers, hucksters and suckers, who have embedded an appetite for believe-whatever-you-want fantasy into the national DNA, argues Kurt Andersen, author of a new book, “Fantasyland: How America Went Haywire, a 500-Year History.” Kwame Anthony Appiah, NYU professor, philosopher, and author of fiction and nonfiction books questions him about the bold claim that America’s love of the fantastic has made this country exceptional in a way that has yet to be understood?
