Remember Parkinson's Law, The Peter Principle, (Galbraith's) The McLandress Dimension? Dickson has collected these and other catchy universals, like Ettorre's Observation (""The other line moves faster"") or Nelson Algren's Precepts: ""Never eat at a place called Mom's. Never play cards with a man named Doc. And never lie down with a woman who's got more troubles than you."" Some are less familiar but instantly verifiable, such as Dibble's First Law of Sociology (""Some do, some don't""). Every once in a while, Dickson sneaks in a real jab (Nixon's Principle--""If two wrongs don't make a right, try three""), or a low blow (Cole's Law--""Thinly sliced cabbage""). But for the most part, he's found the immutables. ""If all economists were laid end to end, they still wouldn't reach a conclusion."" Or that old Army Law: ""If it moves, salute: if it doesn't move, pick it up; and if you can't pick it up, paint it."" What does it all add up to? According to Abbott's Admonition, ""If you have to ask, you're not entitled to know.
