Richard Posner is an influential legal theorist and author and currently a judge on the United States Court of Appeals for the Seventh Circuit. Posner attended Yale as an undergraduate, and was first in his class at Harvard Law School. Following his graduation from Harvard, Posner clerked for Justice William J. Brennan Jr.; he later worked as assistant to the Solicitor General of the United States. In 1969, Posner began teaching at the University of Chicago Law School, where he remains a Senior Lecturer to this day. In 1981, Posner was appointed to Seventh Circuit's Court of Appeals. Posner helped found the law and economics movement, which argues that the primary goal of law should be outcomes that are economically sensible and efficient rather than "just." Known for his eclectic mix of beliefs, Posner can't be pigeonholed as a liberal or a conservative: he has written that marijuana should be legalized and also that there are times when "torture should be used." Posner was the founding editor of the Journal of Legal Studies and (with Orley Ashenfelter) the American Law and Economics Review. Posner is the author of dozens of books, including Public Intellectuals, and The Problems of Jurisprudence. His latest work, How Judges Think, will be published in April 2008.
