Politics is a noble, but also a dirty, business. To gain election - and retain office - in a democratic system, politicians are frequently compelled to be dishonest. They engage in benevolent lying because obstruction by stupid voters will otherwise stop them advancing the national interest as they see it.'So claims the author of this eye-opening book, which straddles politics, philosophy, morality and economics. Alex Rubner's own background as an economist advising policy-makers gives authority to his words and a personal dimension to his illustrations.
