This week we're revisiting some of the best Takeaway interviews from the last year. Here, John talks with Jonah Lehrer, science journalist and author of "Imagine: How Creativity Works," about what made some of history's most creative minds tick. They'll discuss W.H. Auden's drug of choice and why Skype hasn't replaced the face-to-face encounter.
This interview was originally broadcast on March 23, 2012.
