Out of book ...

... More Than Machine. (Hat tip, Dave Lull.)

... isn't it precisely when people refuse to get "out of book"—just following orders or playing their role—that we find them least human? Likewise, when we get "out of book," we are at our most human. Think of the difference between the waiter who runs through the usual routine and the one who responds to your order with a witticism. Remaining alive to what is mechanical or original in our own behavior can preserve a sense of human difference.
