PERSPECTIVES: The story goes that there are three men on a train leaving England for Scotland. One, an economist, another, a logician and the third is a mathematician. As they cross the border into Scotland they see a brown cow in a field standing parallel to the train and the window that is their vantage point. Says the economist, ‘Look, the cows in Scotland are brown.’ The logician replies, ‘No. There are cows in Scotland of which at least one is brown.’ Then, the mathematician: ‘No. There is at least one cow in Scotland, of which one side appears to be brown.’
