POSNER* In this Madison Lecture, Chief Judge Posner advocates a pragmaticapproach to constitutionaldecisionmaking, criticizingconstitutional theorists who conceal their normative goals in vague and unworkable principles of interpretation. After dis- cussingspecific constitutionaltheories as well as the legal academy's increasingreli- ance on theory in genera Posner demonstrates the ineffectuality of constitutional theory, using the Supreme Court's decisions in United States v. Virginia and Romer v. Evans as examples. He argues not that these cases were necessarily wrongly decided, but that the opinions lack the empiricalsupport diat is crucial to sound constitutionaladjudication. Posnerurges law professors to focus theirschol- arship on forms of inquiry that will actually prove usefid to judges and concludes by asking that judges themselves recognize and acknowledge the limitationsof their empiricalknowledge INTRODUCrION Constitutional theory, as I shall use the term, is the effort to de- velop a generally accepted theory to guide the interpretation of the Constitution of the United States.
