Judge Richard Posner is one of the most prolific and interesting writers of our day, from topics of legal jurisprudence to economics in a capitalist democracy. He’s one of the most-cited legal scholars of the 20th century and still writes his own legal opinions. Judge Posner is an intellectual that it’s tough to disagree with, and is a massive influence on the law and economics movement. Judge Posner, who began his legal career as a law clerk for Justice William Brennan, currently presides over the Seventh Circuit for the United States Court of Appeals.
