Read this first. This is a first map of a large subject. Each school is a family of views, and its thinkers often disagree with one another, so every summary simplifies. We describe each school in terms its own followers would accept and give the strongest criticism beside it. Read the original works before you cite anyone, and check your own course's reading list. This is general information, not legal advice.

What is law?

A self-contained system of principles. Cases are decided by applying general concepts to facts, by reasoning that follows from them, with little need to bring in policy or politics.

Law and morality

Kept out of the judge's reasoning. Policy choices belong to the legislature.

Where does its authority come from?

The internal logic and coherence of the legal system, ideally as set out by scholars.

How should judges decide?

Deductive reasoning from rules and doctrine. Predictability and neutrality are the aims.

The question it asks

Can a judge decide by logic alone?

Main criticism

Realists said the logic hides policy choices and judges' preferences. Jhering himself turned against the 'heaven of legal concepts' in his later work.

Legacy today

The case method in American law schools, the style of reasoning in civil codes, and every 'the rule is the rule' approach.

Key thinkers

Christopher Columbus Langdell, Georg Friedrich Puchta, Bernhard Windscheid, Rudolf von Jhering (early work).
