A liberal society stands on the proposition that we should all take seriously the idea that we might be wrong. This means we must place no one, including ourselves, beyond the reach of criticism; it means that we must allow people to err, even where the error offends and upsets, as it often will." So writes Jonathan Rauch in Kindly Inquisitors, which has challenged listeners for more than 20 years with its bracing and provocative exploration of the issues surrounding attempts to limit free speech.

In 1831, Alexis de Tocqueville, a young French aristocrat and civil servant, made a nine-month journey through the eastern United States.

The leviathan is the vast unity of the State. But how are unity, peace, and security to be attained? Hobbes’ answer is sovereignty, but the resurgence of interest today in Leviathan is due less to its answers than its methods: Hobbes sees politics as a science capable of the same axiomatic approach as geometry.

This expanded edition of John Stuart Mill's Utilitarianism includes the text of his 1868 speech to the British House of Commons defending the use of capital punishment in cases of aggravated murder.

Or been told that being obese is healthy, that there is no such thing as biological sex, or that only White people can be racist? Are you confused by these ideas, and do you wonder how they have managed to challenge the logic of Western society? In this probing volume, Helen Pluckrose and James Lindsay document the evolution of the dogma that informs these ideas, from its coarse origins in French postmodernism to its refinement within activist academic fields.

The foundation for all modern economic thought and political economy, The Wealth of Nations is the magnum opus of Scottish economist Adam Smith, who introduces the world to the very idea of economics and capitalism in the modern sense of the words.

Milton Friedman and his wife, Rose, teamed up to write this most convincing and readable guide, which illustrates the crucial link between Adam Smith's capitalism and the free society. They show how freedom has been eroded and prosperity undermined through the rapid growth of governmental agencies, laws, and regulations.

What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, and which ones should be fostered and which ones should be discouraged? How does knowing differ from believing?

Human history is full of the stories of peasants, subjects, and tribes. Yet the concept of the “citizen” is historically rare — and was among America’s most valued ideals for over two centuries. But without shock treatment, warns historian Victor Davis Hanson, American citizenship as we have known it may soon vanish.

From his perspective in Renaissance Italy, Machiavelli's aim in this classic work was to resolve conflict with the ruling prince, Lorenzo de Medici. Machiavelli based his insights on the way people really are rather than an ideal of how they should be. This is the world's most famous master plan for seizing and holding power. Astonishing in its candor The Prince even today remains a disturbingly realistic and prophetic work on what it takes to be a prince, a king, or a president.

Published in 1748, An Enquiry Concerning Human Understanding is Scottish empiricist philosopher David Hume's distillation of his mature philosophy.

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

Two contrasting reflections by Aristotle which cover very particular ground. In 'On the Soul', Aristotle presents his view of the 'life essence' which, he argues, is possessed by living things whether plants, animals or humans. Not a 'soul' in the generally accepted Western use of the term, this 'soul', he says, is a life force that is indivisible from the organism that possesses it.

Published in 1797, the Critique of Pure Reason is considered to be one of the foremost philosophical works ever written. In the Critique of Pure Reason, Immanuel Kant explores the foundation of human knowledge and its limits, as well as man's ability to engage in metaphysics.

Critique of Judgement was published in 1790 and is divided into two parts, the Critique of Aesthetic Judgement and the Critique of Teleological Judgement. Our ‘judgements of taste’, as Kant describes our aesthetic judgements, have both a personal and a universal function: personal, because we have a subjective aesthetic response to the ‘agreeable’, the ‘beautiful’, the ‘sublime’ and the ‘good’; but also there is a ‘universal’ aspect because our aesthetic response has a ’disinterested’ element. This brings under Kant’s spotlight, for example, the concept of beauty and the perception of beauty. 

In this delightfully lucid and accessible audiobook, America’s foremost philosopher, Mortimer J. Adler, explores 10 errors in the development of modern thought and examines the serious consequences they have in our everyday lives. Some of these mistakes include: (1) The mistake of identifying happiness with a good time rather than with that which is good for us; (2) The failure to differentiate between the perceptual and the conceptual realms of thought, by which the human mind is distinguished from the animal mind; and (3) The failure to acknowledge free will, which leads to the rejection of moral responsibility.
