there are only four types of officer. First, there are the lazy, stupid ones. Leave them alone, they do no harm. Second, there are the hard-working intelligent ones. They make excellent staff officers, ensuring that every detail is properly considered. Third, there are the hard working, stupid ones. These people are a menace and must be fired at once. They create irrelevant work for everybody. Finally there are the intelligent lazy ones. They are suited for the highest office.’’
