The Mengzi is one of the very greatest works of world literature and philosophy, and it is perhaps the single most influential Confucian text of all time. Of all the Confucian classics, it is also the one most likely to speak to a contemporary audience. The Mengzi contains the dialogues, debates and sayings of Mengzi, a Confucian sage of the fourth century BCE. (He is also known by the Latinization of his name, 'Mencius'.)

One of the great fears many of us face is that despite all our effort and striving, we will discover at the end that we have wasted our life. In A Guide to the Good Life, William B. Irvine plumbs the wisdom of Stoic philosophy, one of the most popular and successful schools of thought in ancient Rome, and shows how its insight and advice are still remarkably applicable to modern lives. In A Guide to the Good Life, Irvine offers a refreshing presentation of Stoicism, showing how this ancient philosophy can still direct us toward a better life.

This Leibniz collection contains some of the philosopher’s most important works and ideas, spans three decades and illuminates the fascinating intellectual journey undertaken by him in his quest for truth. A prodigious polymath, Leibniz was a mathematician, philosopher, physicist and statesman and engaged with a sweeping range of ideas and disciplines, striving throughout his life to be at the cutting edge of scientific thinking. These Principal Essays are arranged in chronological order.

Entertaining and insightful, David Hume's Dialogues Concerning Natural Religion and The Natural History of Religion are considered to be among the most important philosophical works on the topic of religion. Each investigates the formation and consequences of religious belief.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

Ray Dalio, one of the world's most successful investors and entrepreneurs, shares the unconventional principles that he's developed, refined, and used over the past 40 years to create unique results in both life and business - and which any person or organization can adopt to help achieve their goals.

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.

As former tutor and adviser to Emperor Nero, philosopher and statesman Seneca was acutely aware of how short life can be - his own life was cut short when the emperor ordered him to commit suicide (for alleged involvement in a conspiracy). And Seneca proved true to his words - his lifelong avowal to Stoicism enabled him to conduct himself with dignity to the end. During his rich and busy life, Seneca wrote a series of essays that have advised and enriched the lives of generations down to the present day.

Conjectures and Refutations is one of Karl Popper’s most wide-ranging and popular works, notable not only for its acute insights into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge but our aims and our standards grow through an unending process of trial and error.

On Anarchism provides the reasoning behind Noam Chomsky's fearless lifelong questioning of the legitimacy of entrenched power. In these essays, Chomsky redeems one of the most maligned ideologies, anarchism, and places it at the foundation of his political thinking. Chomsky's anarchism is distinctly optimistic and egalitarian. Moreover, it is a living, evolving tradition that is situated in a historical lineage; Chomsky's anarchism emphasizes the power of collective, rather than individualist, action.

On War was first published in 1832, at a time when muskets and cavalry were a dominating presence on the battlefield. Yet in the 21st century it remains a much-read and studied treatise on the subject – perhaps the most important European classic of its kind – and this despite the author’s demise before he could finish what was an extended review of the whole subject of military strategy. Why is that?

The appearance of the famous (and massive) volumes of Rothbard's Austrian Perspective on the History of Economic Thought in a new edition is cause for great celebration. Every paragraph bursts with intellectual energy and the author's fiery passion to tell the listener the remarkable story of economics. Many reviewers have remarked that Rothbard's accomplishment seems superhuman. He seems to have read everything. His originality is overwhelming. His passion for liberty and integrity in science is evident.

As philosophy professor Taylor Carman explains in his helpful introduction, Edmund Husserl (1859-1938) was the founder of modern phenomenology, one of the most important and influential movements of the 20th century. Ideas, published in 1913 – its full title is Ideas for a Pure Phenomenology and Phenomenological Philosophy – was the key work. It is arguably ‘the most fundamental and comprehensive statement of the fundamental principles of Husserl’s mature philosophy’.

Nietzsche never recovered from his mental breakdown in 1889 and therefore was unable to further any plans he had for the ‘magnum opus’ he had once intended, bringing together in a coherent whole his mature philosophy. It was left to his close friend Heinrich Köselitz and his sister Elizabeth Förster-Nietzsche to go through the remaining notebooks and unpublished writings, choosing sections of particular interest to produce The Will to Power, giving it the subtitle An Attempted Transvaluation of All Values.

On Liberty is a book by John Stuart Mill, one of the most celebrated philosophers on the subject of leadership and governing ideals. The book focuses on Mill's philosophy on utilitarianism which is one of his defining principles. The principles of the book are focused on developing a relationship between the ruling authority and liberty.

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. The speech is significant both because its topic remains timely and because its arguments illustrate the applicability of the principle of utility to questions of large-scale social policy.

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.

Kant published this work in 1795, during the aftermath of the American Revolution and the French Revolution. The high hopes of the European Enlightenment had been dampened by the Reign of Terror in which tens of thousands of people died, and the perpetual cycle of war and temporary armistice seemed to be inescapable. Kant's essay is best known as an early articulation of the idea of a league of nations that could bring an end to all hostilities. Today, the United Nations continues to pursue that dream, but lasting peace still seems to be wishful thinking.

In 1831, Alexis de Tocqueville, a young French aristocrat and civil servant, made a nine-month journey through the eastern United States. The result was Democracy in America, a monumental study of the strengths and weaknesses of the nation’s evolving politics. His insightful work has become one of the most influential political texts ever written on America.

"Anarchy" (1907) is a political classic written by famous anarchist Errico Malatesta. "Anarchy is a word which comes from the Greek, and signifies, strictly speaking, without government: the state of a people without any constituted authority. Before such an organization had begun to be considered possible and desirable by a whole class of thinkers, so as to be taken as the aim of a party (which party has now become one of the most important factors in modern social warfare)."

A Short History of Ethics is a significant contribution written by one of the most important living philosophers. It remains an important work, ideal for all students interested in ethics and morality.

Hannah Arendt's penetrating observations on the modern world, based on a profound knowledge of the past, have been fundamental to our understanding of our political landscape. On Revolution is her classic exploration of a phenomenon that has reshaped the globe. From the 18th-century rebellions in America and France to the explosive changes of the 20th century, Arendt traces the changing face of revolution and its relationship to war while underscoring the crucial role such events will play in the future.

The Crowd: A Study of the Popular Mind is a seminal work on crowd psychology by Gustave Le Bon (1841-1931), a French social psychologist. He observes that a crowd forms when an influential idea unites a number of individuals and prompts them to act towards a common goal. In a crowd, the conscious personality of the individual is submerged and dominated by the collective mind. Furthermore, every sentiment becomes contagious to a degree that individuals readily sacrifice their personal interest to the collective.

The Constitution of Liberty is considered Hayek's classic statement on the ideals of freedom and liberty, ideals that he believes have guided - and must continue to guide - the growth of Western civilization. Here, Hayek defends the principles of a free society, casting a skeptical eye on the growth of the welfare state and examining the challenges to freedom posed by an ever-expanding government.

Forged during the tumultuous but triumphant postwar years when America came of age as a world power, The Irony of American History is more relevant now than ever before. Cited by politicians as diverse as Hillary Clinton and John McCain, Niebuhr's masterpiece on the incongruity between personal ideals and political reality is both an indictment of American moral complacency and a warning against the arrogance of virtue.

Ayn Rand here sets forth the moral principles of Objectivism, the philosophy that holds human life - the life proper to a rational being - as the standard of moral values and regards altruism as incompatible with human nature, with the creative requirement of survival, and with a free society.

Hannah Arendt's insightful observations of the modern world, based on a profound knowledge of the past, constitute an impassioned contribution to political philosophy. In Between Past and Future, Arendt describes the perplexing crises modern society faces as a result of the loss of meaning of the traditional key words of politics: justice, reason, responsibility, virtue, and glory. Through a series of eight exercises, she shows how we can redistill the vital essence of these concepts and use them to regain a frame of reference for the future.

"George Washington's Farewell Address" is a letter written by George Washington to the people of the United States of America. It was Washington's valedictory after 20 years of service to the new nation. It is a classic statement of republicanism, warning Americans of the political dangers they can and must avoid if they are to remain true to their values.

'The two foes of human happiness are pain and boredom.' Arthur Schopenhauer (1788-1860) was one of the most influential philosophers of the 19th century because his humanistic, atheistic, if pessimistic views chimed with a new secularism that was emerging from a Western society dominated by religion. Despite his rather forbidding image (and a few outdated views), he is one of the most approachable German philosophers, and this is certainly evident in these two key works, The Wisdom of Life and Counsels and Maxims.
