Groundwork of the Metaphysics of Morals is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most influential in the field. Kant conceives his investigation as a work of foundational ethics - one that clears the ground for future research by explaining the core concepts and principles of moral theory, and showing that they are normative for rational agents.

John Stuart Mill (1808-1873) was a torchbearer for liberal thought in the 19th century, including liberty of the individual and freedom of speech, and he championed women's suffrage in Parliament. A remarkable man - he learned Greek aged three and at eight had read Herodotus, Xenophon and Plato - he campaigned all his life for a just society. These two essays are his key works.

First published in 1859, John Stuart Mill's On Liberty is an exhaustive exploration of social and civic liberty, its limits, and its consequences. Mill's work is a classic of political liberalism that contains a rational justification of the freedom of the individual in opposition to the claims of the state.

Groundwork of the Metaphysics of Morals (1785) is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most important in the field. Kant examines the core concepts and principles of moral theory, showing that they are normative for rational agents. He aspires to lay bare the fundamental principle of morality and prove that it applies to us. Kant offers the argument that the rightness of an action is determined by the character of the principle that a person chooses to act upon.

A celebration of individuality, diversity, and nonconformity, On Liberty still makes a persuasive argument for what John Stuart Mill believed to be humankind’s essential liberties: the freedoms of speech, assembly, and the pursuit of pleasure, so long as one’s actions do not impede the liberty of another. These freedoms, he maintained, result in a far more successful society than one ruled by the tyranny of the majority. This treatise on personal liberty has inspired debate since its publication in 1859, and has provided the foundation for modern liberal political thought.

Underlain by an acute sense of ethics, this provided the basis for his strongly declared, wide-ranging views on many subjects: prohibition of cock-fighting, liberty of the press, universal suffrage, the removal of religious tests for office and even hunting. All were radical ideas for his time. He also proposed the decriminalisation of homosexuality, though even he did not dare to publish his essay on this subject during his lifetime. But An Introduction to the Principles of Morals and Legislation was his major work.

Immanuel Kant’s Critique of Pure Reason can lay claim to being the most important single work of modern philosophy, a work whose methodology, if not necessarily always its conclusions, has had a profound influence on almost all subsequent philosophical discourse. In this work Kant addresses, in a groundbreaking elucidation of the nature of reason, the age-old question of philosophy: “How do we know what we know?” and the limits of what it is that we can know with certainty.

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.

What are our obligations to others as people in a free society? Should government tax the rich to help the poor? Is the free market fair? Is it sometimes wrong to tell the truth? Do individual rights and the common good conflict? These questions are at the core of our public life today - and at the heart of Justice, in which Michael J. Sandel shows how a surer grasp of philosophy can help us to make sense of politics, morality, and our own convictions as well.

Durant lucidly describes the philosophical systems of such world-famous “monarchs of the mind” as Plato, Aristotle, Francis Bacon, Spinoza, Kant, Voltaire, and Nietzsche. Along with their ideas, he offers their flesh-and-blood biographies, placing their thoughts within their own time and place and elucidating their influence on our modern intellectual heritage. This book is packed with wisdom and wit.

Hailed as the most compelling biography of the German dictator yet written, Ian Kershaw's Hitler brings us closer than ever before to the heart of its subject's immense darkness. From his illegitimate birth in a small Austrian village to his fiery death in a bunker under the Reich chancellery in Berlin, Adolf Hitler left a murky trail, strewn with contradictory tales and overgrown with self-created myths. One truth prevails: the sheer scale of the evils that he unleashed on the world has made him a demonic figure without equal in the 20th century.

One of the most influential works of this century, The Myth of Sisyphus and Other Essays is a crucial exposition of existentialist thought. Influenced by works such as Don Juan and the novels of Kafka, these essays begin with a meditation on suicide; the question of living or not living in a universe devoid of order or meaning.

This book consists of two parts: the essay "The Idea of Public Reason Revisited" and "The Law of Peoples", a major reworking of a much shorter article by the same name. Taken together, they are the culmination of more than 50 years of reflection on liberalism and on some of the most pressing problems of our times.

The world-renowned philosopher and author of the best-selling Justice explores the central question of our time: What has become of the common good? World-renowned philosopher Michael J. Sandel argues that to overcome the crises that are upending our world, we must rethink the attitudes toward success and failure that have accompanied globalization and rising inequality. Sandel shows the hubris a meritocracy generates among the winners and the harsh judgment it imposes on those left behind, and traces the dire consequences across a wide swath of American life.

Immanuel Kant's Fundamental Principles of the Metaphysics of Morals, first published in 1785, lays out Kant's essential philosophy and defines the concepts and arguments that would shape his later work. Central to Kant's doctrine is the categorical imperative, which he defines as a mandate that human actions should always conform to a universal, unchanging standard of rational morality.
