The Schools of Jurisprudence — a Combined Map

When a paper asks you to “explain the different schools of jurisprudence”, it wants breadth, not depth — a clear, comparative map of all five, each in a few crisp lines, showing how each answers the one big question: what is law? This topic is your one-paragraph tour, and a compact comparison table wins these marks.

The five schools, side by side

Each school is one answer to “what is law, and where does its authority come from?” Keep this skeleton and you can write on any of them:

Analytical / Positivist — law is what is laid down. Studies law as it is, separate from morals. Austin (command of the sovereign + sanction), Hart (union of primary and secondary rules), Kelsen (pyramid of norms topped by the Grundnorm). Strength: precision and clarity. Weakness: ignores justice and purpose.
Natural Law — law must be just to be law. Studies law as it ought to be; above human law stands a higher law of reason and morality (lex injusta non est lex). Aquinas, Locke, Fuller, Finnis. Strength: source of human rights. Weakness: vague, no fixed content.
Historical — law grows, it is not made. Studies law as it was; law is the product of a people’s history and spirit. Savigny (Volksgeist), Maine (status to contract). Strength: explains custom and continuity. Weakness: under-values legislation and reform.
Sociological — law is a tool for social ends. Studies law as it works in society; law balances competing social interests. Ihering (purpose), Ehrlich (living law), Pound (social engineering). Strength: welfare orientation, concern for results. Weakness: no precise scale for “balancing”.
Realist — law is what the courts do. A sociological offshoot focused on the judicial process; the true law is the actual decision, not the paper rule. Holmes, Gray, Frank (American); Olivecrona, Ross (Scandinavian). Strength: realism about how cases are decided. Weakness: exaggerates the judge’s freedom.

Comparative anchor: Analytical asks what the law IS; Natural Law asks what it OUGHT to be; Historical asks what it WAS; Sociological asks what it DOES; Realist asks what the courts WILL DO.

In Simple Terms: Five schools, five verbs — is, ought, was, does, will do. If you can attach the right verb and one or two names to each school, you can answer any “schools” question at breadth.

💡 EXAM TIP — Answering the “different schools” question

The trap. Candidates pour everything they know about Austin into a “schools” answer and run out of time before reaching the other four — losing marks for coverage.

What to write. A short paragraph per school in the fixed order (Analytical, Natural, Historical, Sociological, Realist), each with its one-line verb (is/ought/was/does/will-do), its lead jurist, and one line of criticism — then a two-line comparison table if time allows.

Why it scores. The examiner is testing breadth and organisation, not depth on one man; a balanced five-part map reads as mastery of the whole subject.

Case Laws

Kesavananda Bharati v State of Kerala (1973) — a single judgment in which several schools are visible: positivist (validity of the amendment), natural-law (basic structure as a higher standard), and sociological (the Constitution as an instrument of social change).
