Mohandas Gandhi, the Mahatma, was fond of the parable of the blind men and the elephant. One, grabbing the elephant’s tail, said that an elephant was like a rope. Another, holding its trunk, said it was like a snake. A third, touching one of its legs, protested that it was really like a tree. Those touching its ears or sides made still other claims. All were “right from their respective points of view”, Gandhi wrote in the mid-1920s, “and wrong from the point of view of one another, and right and wrong from the point of view of the man who knew the elephant”.
