The first 13 of the AEI Walter Berns Constitution Day Lectures are now collected in one volume. Given by distinguished scholars, judges, and political figures--and edited by AEI Senior Fellow Gary J. Schmitt--the lectures cover a host of topics providing a deeper understanding of the US constitutional order and its underlying principles. The volume also reissues a 2011 panel discussion by Christopher DeMuth, Leon R. Kass, and Jeremy A. Rabkin honoring longtime AEI colleague Walter Berns's still relevant and important scholarship on the Constitution and the American republic.
