Summary: One in every 150 children is now diagnosed to be somewhere on the mysterious spectrum of autism. We step back from the controversies about the causes and cures of autism and explore one family's experience with an autistic child. Jennifer Elder, an artist, and Paul Collins, a literary historian, have unearthed a vivid history of people grappling with autism, before it had a name. And they share what all of this is teaching them about what it means to be human.
