Letter from Birmingham Jail

Martin Luther King Jr. 1963 Freedom & Liberty Grades 9–12 · Rhetoric Stage
Written from a jail cell in April 1963, King's Letter from Birmingham Jail defends nonviolent civil disobedience by drawing on Augustine, Aquinas, and the natural law tradition to argue that unjust laws are no laws at all.

What King Argued

Responding to eight white clergymen who called his protests "unwise and untimely," King built a systematic defense of civil disobedience. Drawing on Augustine and Aquinas, he distinguishes just from unjust laws: "An unjust law is a code that a numerical or power majority group compels a minority group to obey but does not make binding on itself." He also expressed "great disappointment" with white moderates who preferred order to justice.

The Natural Law Tradition

King argues using the tools of Western philosophy: Augustine ("An unjust law is no law at all"), Aquinas (just law must be rooted in eternal and natural law), Martin Buber (segregation treats persons as things), and Paul Tillich (sin is separation). King demonstrates that the civil rights movement was a fulfillment of Western civilization's deepest principles, not a break with them.
