PROBLEMS OF JURISPRUDENCE, THE

Examining how judges go about making difficult decisions, Posner argues that they cannot rely on either logic or science, but must fall back on a grab bag of informal methods of reasoning that owe less than one might think to legal training and experience. Indeed, he reminds us, the greatest figures in American law have transcended the traditional conceptions of the lawyer's craft. Robert Jackson did not attend law school and Benjamin Cardozo left before getting a degree. Holmes was neither the most successful of lawyers nor the most lawyerly of judges. Citing these examples, Posner makes a plea for a law that frees itself from excessive insularity and takes all knowledge, practical and theoretical, as grist for its mill. The pragmatism that Posner espouses implies looking at problems concretely, experimentally, without illusions, with an emphasis on keeping diverse paths of inquiry open, and, above all, with the insistence that social thought and action be evaluated as instruments to desired human goals rather than as ends in themselves. In making his arguments, he discusses notable figures in jurisprudence from Antigonc to Ronald Dworkin as well as recent movements ranging from law and economics to civic republicanism, and feminism to libertarianism. All are subjected to Posner's stringent analysis in a fresh and candid examination of some of the deepest problems presented by the enterprise of law.
