Lawrence Lessig is Roy L. Furman Professor of Law and Leadership at Harvard Law School. He is the author of many books, including Code 2.0, Free Culture, Remix, and Republic, Lost, and most recently, America, Compromised.

"A magnificent achievement, and one of the best books ever written about American constitutional law. Lessig offers a brilliant, sympathetic account of the full sweep of constitutional history, from the founding era to the modern era. Transcending political debates, he argues that the Supreme Court has been faithful to the Constitution's original meaning- while also vindicating new understandings of both liberty and equality. A book for the ages." --Cass R . Sunstein, Robert Walmsley University Professor, Harvard Law School, and author of How Change Happens

"Fidelity and Constraint is the most ambitiously theorized study of American constitutional law in decades. Lessig imaginatively deploys the ideas of "translation" and "fidelity to judicial role" to re-tell constitutional history and thereby cast fresh illumination on current doctrine as well as old debates. The book is a marvel of learning, insight, and edifying provocation." --Richard Fall on, Story Professor of Law, Harvard Law School

"In Fidelity and Constraint, Lawrence Lessig shows us how Supreme Court Justices have sought to translate the past into the present while remaining faithful to their role as judges. Packed with insights about the Supreme Court's history and novel readings of famous cases, this book is as brilliant as it is engaging." --Jack Balkin, Yale Law School

"In this extraordinary book, Larry Lessig develops his groundbreaking theory of constitutional law, based on the idea of translation, and demonstrates the power of his theory with dazzling insights about history and law. Agree or disagree, if you care about constitutional law, you must come to grips with this book." --David A. Strauss, Gerald Ratner Distinguished Service Professor of Law, The University of Chicago, and author of The Living Constitution

"Larry Lessig is a legendarily effective communicator who has developed an audacious and provocative way of both understanding and justifying most of the decisions of the Supreme Court. He presents them as mixtures of good-faith attempts to remain faithful to the original project of the Constitution while being attentive to maintaining the Court itself as a flourishing part of government. There are illuminating insights on every page. Even those disinclined to accept his argument in full will find themselves challenged to explain their reservations." --Sanford Levinson, author of Framed: America's 51 Constitutions and the Crisis of Governance
