Robert George has created the Academic Freedom Alliance, a group that intends to offer moral and legal support to professors who are under fire, and even to pay for their legal teams if necessary. George was inspired, he told me, by a nature program that showed how elephant packs will defend every member of the herd against a marauding lion, whereas zebras run away and let the weakest get killed off. “The trouble with us academics is we’re a bunch of zebras,” he said. “We need to become elephants.”
