The freedom of association is surely the humblest and least-touted First Amendment right, and yet, as Luke Sheahan explains in this keynote lecture, it is crucial for preserving our liberty and rejuvenating our culture. Natural and freely-chosen human associations are our best defense against a political clerisy that often feels entitled to social engineer American life. Free citizens should be permitted to order their lives around their families, religious congregations, clubs, and other forms of association that are the proper basis for a thriving society.
