Rebecca Brown's lecture at the Holberg Prize Symposium 2007. The Symposium was in honor of Holberg Prize laureate 2007 Ronald Dworkin. Rebecca Brown is Allen Professor of Law at Vanderbilt University, where she teaches courses in constitutional law and theory. Her scholarship sets forth a vision of the U.S. Constitution premised on individual liberty, and explores the relationship between liberty and equality under the Constitution. In recognition of this work, she received the Association of American Law Schools’ Scholarly Paper Award in 1993 and the inaugural Chancellor’s Award for Research at Vanderbilt University in 2003. She is co-convenor of the biennial Constitutional Theory Conference. Professor Brown will be leaving Vanderbilt to join the law faculty at the University of Southern California in the summer of 2008.
