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.

First published in 1936, Keynes’ ideas had evolved during the difficulties following World War 1 in Europe, and the US crash and the Depression of the 1920s-'30s and the misery of mass unemployment. He deplored the situation where a few individuals or companies stored massive wealth while vast numbers experienced poverty and insecurity (his alarm bells ring today!) and sought to promote initiatives where governments could intervene with social projects to keep money fluctuating.

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.

Human Action is the most important book on political economy you will ever own. It was (and remains) the most comprehensive, systematic, forthright, and powerful defense of the economics of liberty ever written. This is the Scholar's Edition: accept no substitute. You will treasure this volume. The Scholar's Edition is the original, unaltered treatise (originally published in 1949) that shaped a generation of Austrians and made possible the intellectual movement that is leading the global charge for free markets.

To understand world politics, you need to understand how states think. Are states rational? Much of international relations theory assumes that they are. But many scholars believe that political leaders rarely act rationally. The issue is crucial for both the study and practice of international politics. John J. Mearsheimer and Sebastian Rosato argue that rational decisions in international politics rest on credible theories about how the world works and emerge from deliberative decision‑making processes.

What are the grand dynamics that drive the accumulation and distribution of capital? Questions about the long-term evolution of inequality, the concentration of wealth, and the prospects for economic growth lie at the heart of political economy. But satisfactory answers have been hard to find for lack of adequate data and clear guiding theories.

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.

The front cover of the second edition of Language, Truth and Logic carried this statement in capital letters: ‘THE CLASSIC TEXT WHICH FOUNDED LOGICAL POSITIVISM - AND MODERN BRITISH PHILOSOPHY.’ It was a bold statement, but the book, first published in 1936 when A. J. Ayer was just 25 and a lecturer on philosophy at Christ Church, Oxford, drew unstinting praise from leading figures in the field, including Bertrand Russell.

Malthus predicted a grim future with geometrical population growth, versus food production that increases only arithmetically. He claimed that this would result in famine and starvation unless births were controlled. It is called the Malthusian catastrophe, in which humans would disregard the limits of natural resources and the world would be plagued by famine and disease.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

The Consolation of Philosophy is one of the key works in the rich tradition of Western philosophy, partly because of the circumstances in which it was written. Anicius Manlius Severinus Boethius (c480-c524) was of aristocratic Roman birth and became consul and then master of offices at Ravenna, one of the highest posts under the Ostrogothic Roman ruler Theodoric. But Boethius was unjustly charged with treason in 524, and this led to house arrest, then torture and execution.

No skill is more important in today's world than being able to think about, understand, and act on information in an effective and responsible way. What's more, at no point in human history have we had access to so much information, with such relative ease, as we do in the 21st century. But because misinformation out there has increased as well, critical thinking is more important than ever. These 24 rewarding lectures equip you with the knowledge and techniques you need to become a savvier, sharper critical thinker in your professional and personal life.

The Economic Consequences of the Peace (1919) was one of the most important documents to come out of World War I – specifically the period of the Armistice and the subsequent settlement negotiations. And, a century on, it remains of particular relevance to our times – an uncompromising and forthright analysis of how international diplomacy can be suffused by personalities, prejudices, personal ambition and outright, uncontrolled feelings of revenge.

A million-copy seller, Henry Hazlitt’s Economics in One Lesson is a classic economic primer. But it is also much more, having become a fundamental influence on modern “libertarian” economics of the type espoused by Ron Paul and others. Called by H. L. Mencken “one of the few economists in history who could really write,” Henry Hazlitt achieved lasting fame for this brilliant but concise work.

Throughout the twentieth century, The Protestant Ethic and the Spirit of Capitalism was regarded as an important sociological and economic text, continuing into the twenty-first century, when extreme capitalism has continued to come under fire. Weber's work provided a history, from where the profit motive could be ethically justified. Max Weber combined his interests in sociology, political economy and history to give perspective to his analysis. Concentrating principally on the experience of the West, he returned to the time when religion, its concepts and practice, dominated society.

First published in 1936, Keynes’ ideas had evolved during the difficulties following World War 1 in Europe, and the US crash and the Depression of the 1920s-'30s and the misery of mass unemployment. He deplored the situation where a few individuals or companies stored massive wealth while vast numbers experienced poverty and insecurity (his alarm bells ring today!) and sought to promote initiatives where governments could intervene with social projects to keep money fluctuating.

The Theory of Moral Sentiments (1759) was the first major text by Adam Smith who, seven years later, was to publish what was to become one of the major economic classics, The Wealth of Nations (1776). However, Smith regarded The Theory of Moral Sentiments as his most important work because in it he identified the profound human instinct to act not necessarily in self-interest but through, as he phrased it, a ‘mutual sympathy of sentiments’.

John Locke (1632-1704) was a product of his troubled times: he lived through the English Civil War, the Interregnum, the Restoration, Monmouth’s Rebellion, the Bloody Assizes and the Glorious Revolution. His empirical thinking was very much directed at finding rational solutions to the root causes of those troubles.

Towards the end of his life, Seneca the Younger (c4 BCE-65 CE) began a correspondence with a friend in Sicily, later collected under the title The Moral Epistles. In these 124 letters, Seneca expresses, in a wise, steady and calm manner, the philosophy by which he lived - derived essentially from the Stoics. The letters deal with a variety of specific topics - often eminently practical - such as 'On Saving Time', 'On the Terrors of Death', 'On True and False Friendships', 'On Brawn and Brains' and 'On Old Age and Death'.

Though it first aroused anger and controversy rather than admiration and acceptance, A Theologico-Political Treatise was a landmark in the analysis of theology (with particular reference to the Bible and its Jewish and Christian interpretations) and its relationship to philosophy and politics. Spinoza’s scholarly analysis, based on careful study, demonstrated that the Bible was composed by many writers over the centuries - and that even the Pentateuch, the first five books, were not the work of Moses, as was generally assumed at the time.
