This document summarizes John Austin's analytical positivism school of jurisprudence. It outlines that Austin viewed law as the command of the sovereign, with three key aspects: 1) commands are general rules for a community backed by sanctions, 2) a sovereign is the ultimate human source of law, and 3) law and morality are separate, with law defined by its coercive power rather than moral content. The document also notes chief legal philosophers of this school and some criticisms of Austin's theory.
