This book examines the relational dynamics between the U.S. Constitution’s Free Speech Clause and other constitutional rights. The free speech guarantee has intersected with a variety of other constitutional rights. Those intersections have significantly influenced the recognition, scope, and meaning of rights ranging from freedom of the press to the Second Amendment right to bear arms. They have also influenced interpretation of the Free Speech Clause itself. Free speech principles and doctrines have facilitated the recognition and effective exercise of constitutional rights, including equal protection, the right to abortion, and the free exercise of religion. They have also provided mediating principles for constructive debates about constitutional rights. At the same time, in its interactions with other constitutional rights, the Free Speech Clause has also been a complicating force. It has dominated rights discourse and subordinated or supplanted free press, assembly, petition, and free exercise rights. Currently, courts and commentators are fashioning the Second Amendment right to keep and bear arms in the image of the Free Speech Clause. Borrowing the Free Speech Clause for this purpose may turn out to be detrimental for both rights. The book examines the common and distinctive dynamics that have brought free speech and other constitutional rights together. It assesses the products and consequences of these intersections, and draws important lessons from them about constitutional rights and constitutional liberty. Ultimately, the book defends a pluralistic conception of constitutional rights that seeks to leverage the power of the Free Speech Clause but also to tame its propensity to subordinate, supplant, and eclipse other constitutional rights.
