The Morality of Law

Lon L. Fuller

Natural law / legal philosophy

It is a central modern statement of natural law and the rule of law, framing the famous debate with legal positivism.

Synopsis

A natural-law argument that genuine law must meet an inner morality, eight procedural demands of clarity, consistency, and publicity, to count as law at all.

Core passage idea

Paraphrase · Modern copyrighted work

Law has an inner morality: rules must be public, clear, stable, and followable, and a system that flouts these is not truly law.

It ties legality itself to moral standards of fairness in procedure, challenging the idea that any command can count as law.

To avoid a bubble

Pair with H. L. A. Hart, The Concept of Law.

Reading note

Read it as a response to Hart and positivism; the eight principles are the heart of the argument.

Best paired with
