Peter Sagal

Commentator Peter Sagal mourns the loss of science fiction author Philip Jose Farmer. He says Farmer provided him with an important commodity when he was growing up: imaginary people. You can spend your whole life talking and playing with and beating up imaginary people. And from all accounts, many do. But Sagal also wonders if, like him, when they grow up and have to say farewell to childish things, they'll have nothing real to let go of.
