"You know law and business, Colonel Van Gilbert. You know how to serve corporations and increase dividends by twisting the law. Very good. Stick to it. You are quite a figure. You are a very good lawyer, but you are a poor historian, you know nothing of sociology, and your biology is contemporaneous with Pliny."
Here Colonel Van Gilbert writhed in his chair. There was perfect quiet in the room. Everybody sat fascinated—paralyzed, I may say. Such fearful treatment of the great Colonel Van Gilbert was unheard of, undreamed of, impossible to believe—the great Colonel Van Gilbert before whom judges trembled when he arose in court. But Ernest never gave quarter to an enemy.
"This is, of course, no reflection on you," Ernest said. "Every man to his trade. Only you stick to your trade, and I'll stick to mine. You have specialized. When it comes to a knowledge of the law, of how best to evade the law or make new law for the benefit of thieving corporations, I am down in the dirt at your feet. But when it comes to sociology—my trade—you are down in the dirt at my feet. Remember that. Remember, also, that your law is the stuff of a day, and that you are not versatile in the stuff of more than a day. Therefore your dogmatic assertions and rash generalizations on things historical and sociological are not worth the breath you waste on them."
