Abstract: Although the Bill of Rights has existed for two hundred years, the last half century has seen dramatic changes in its meaning and scope. The essays collected in this volume represent the full range of views and interpretations of what these first ten amendments to the U. S. Constitution mean today as guarantors of individual rights. The contributors to this volume are among the most prominent constitutional scholars in the country. Most of the essays are grouped in pairs, each of which offers conflicting positions on current constitutional controversies, including property rights, freedom of religion, freedom of speech, levels of generality in constitutional interpretation, and unenumerated rights. The contributors are: Bruce Ackerman, Mary E. Becker, Ronald Dworkin, Frank H. Easterbrook, Richard A. Epstein, Charles Fried, Mary Ann Glendon, Philip B. Kurland, Frank J. Michaelman, Michael W. McConnell, Richard A. Posner, Kathleen M. Sullivan, John Paul Stevens, David A. Strauss, and Cass R. Sunstein.
