Penguin Liberty is a curated series of historical, political, and legal classic texts relevant to constitutional rights. The First Amendment to the U.S. Constitution states that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof." Featuring writings by John Locke, James Madison, and Roger Williams, this collection addresses religious freedom, including the right to religious belief and expression, and a guarantee that the government neither prefers religion over non-religion nor favors particular faiths over others. A contentious and essential part of our constitutional rights, religious freedom in American life continues to be debated and protected.
