The concept of law lies at the heart of our social and political life. Legal philosophy, or jurisprudence, explores the notion of law and its role in society, illuminating its meaning and its relation to the universal questions of justice, rights, and morality. In this Very Short Introduction audiobook, Raymond Wacks analyzes the nature and purpose of the legal system and the practice by courts, lawyers, and judges.

John Stuart Mill (1806-73) is widely regarded as the leading liberal philosopher, economist, and political theorist of nineteenth century Britain. In his lifetime, he was best known for his System of Logic (1843) and the Principles of Political Economy (1848). Today Mill is chiefly identified with On Liberty (1859), perhaps the definitive text of modern liberal statement of its subject, and probably the single most important work of modern political thought.

In the second edition of his Very Short Introduction, Skinner includes new material on The Prince, showing how Machiavelli developed his neo-classical political theory, through engaging in continual dialogue with the ancient Roman moralists and historians, especially Cicero and Livy. The aim of political leaders, Machiavelli argues, should be to act virtuously so far as possible, but to stand ready "to be not good" when this course of action is dictated by necessity.

Martin Heidegger, considered by some to be the greatest charlatan ever to claim the title of "philosopher", by some as an apologist for Nazism, and by others as an acknowledged leader in continental philosophy, is probably the most divisive thinker of the 20th century. In the second edition of this Very Short Introduction audiobook, Michael Inwood focuses on Heidegger's most important work, Being and Time, to explore its major themes of existence in the world, inauthenticity, guilt, destiny, truth, and the nature of time.

Augustine was arguably the greatest early Christian philosopher. His teachings had a profound effect on medieval scholarship, Renaissance humanism, and the religious controversies of both the Reformation and the Counter-Reformation. Here, Henry Chadwick places Augustine in his philosophical and religious context and traces the history of his influence on Western thought, both within and beyond the Christian tradition.
