What is autism: a devastating developmental disorder, a lifelong disability, or a naturally occurring form of cognitive difference akin to certain forms of genius? Steve Silberman unearths the secret history of autism, long suppressed by the same clinicians who became famous for discovering it. Going back to the earliest days of autism research, Silberman provides long-sought solutions to the autism puzzle, while mapping out a path for our society toward a more humane world in which people with learning differences and those who love them have access to the resources they need to live happier, healthier, more secure, and more meaningful lives.
