Abstract: Critical legal studies is the most important development in progressive thinking about law of the past half century. It has inspired the practice of legal analysis as institutional imagination, exploring, with the materials of the law, alternatives for society. The Critical Legal Studies Movement was written as the manifesto of the movement by its central figure. This new edition includes a revised version of the original text, preceded by an extended essay in which its author discusses what is happening now and what should happen next in legal thought.
