The Republic poses questions that endure: What is justice? What form of community fosters the best possible life for human beings? What is the nature and destiny of the soul? 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?

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.

In Rediscovering Americanism, Mark R. Levin revisits the founders' warnings about the perils of overreach by the federal government and concludes that the men who created our country would be outraged and disappointed to see where we've ended up. Levin returns to the impassioned question he's explored in each of his best-selling books: How do we save our exceptional country? Because our values are in such a precarious state, he argues that a restoration to the essential truths on which our country was founded has never been more urgent.

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.

Both astonishing and prophetic, The Abolition of Man remains one of C. S. Lewis's most controversial works. Lewis sets out to persuade his audience of the ongoing importance and relevance of universal objective values, such as courage and honor, and the foundational necessity of natural law. He also makes a cogent case that a retreat from these pillars of our educational system, even if in the name of "scientism", would be catastrophic. National Review lists it as number seven on their "100 Best Nonfiction Books of the 20th Century".

The Dialogues of Plato rank with the writings of Aristotle as the most important and influential philosophical works in Western thought. In them Plato cast his teacher Socrates as the central disputant in colloquies that brilliantly probe a vast spectrum of philosophical ideas and issues.

#1 New York Times best-selling author Mark Levin explores the philosophical basis of America's foundations and the crisis that faces government today.

First published in 1930, Civilization and Its Discontents is one of the most influential works of pioneering psychologist Sigmund Freud. Focusing on the tension between the primitive drives of the individual and the demands of civilization for order and conformity, Freud draws upon his psychoanalytic theories to explain the fundamental structures, conflicts, and consequences of society.

Schopenhauer was just 30 when his magnum opus, Die Welt als Wille und Vorstellung, a work of considerable learning and innovation of thought, first appeared in 1818.

Much to his chagrin and puzzlement (so convinced was he of its merits), it didn't have an immediate effect on European philosophy, views and culture. It was only decades later that it was recognised as one of the major intellectual landmarks of the 19th century.

Considered to be one of the most important philosophical works of all time, the History of Western Philosophy is a dazzlingly unique exploration of the ideologies of significant philosophers throughout the ages - from Plato and Aristotle through to Spinoza, Kant and the 20th century. Written by a man who changed the history of philosophy himself, this is an account that has never been rivaled since its first publication over 60 years ago.

Published in 1922 during those dark and dreary years of socialism’s near-complete triumph, Socialism stunned the socialist world. Mises has given us a profoundly important treatise that assaults socialism in all its guises, a work that discusses every major aspect of socialism and leaves no stone unturned. A few of the numerous topics discussed include the success of socialist ideas; life under socialism: art and literature, science and journalism; economic calculation under socialism; the ideal of equality; and Marx’s theory of monopolies.

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.

Rerum Novarum, the opening words and the title of the Encyclical issued by Leo XIII, May 15, 1891, on the "Condition of Labor". Although the Encyclical follows the lines of the traditional teaching concerning the rights and duties of property and the relations of employed and employee, it applies the old doctrines specifically to modern conditions.

This brilliantly conceived book is based on a lecture course given by Dr. Leonard Peikoff in 1976 entitled, "The Philosophy of Objectivism". The lectures were attended by Ayn Rand, who helped prepare them and who also joined Peikoff in answering questions.

Often considered the foundation of political liberalism, John Locke's Two Treatises of Government was first published anonymously in 1689, in the wake of England's Glorious Revolution. In The First Treatise of Government, Locke refutes the idea of divine monarchy, while The Second Treatise of Government articulates Locke's philosophy of government, which he based upon his theories of natural rights and the social contract.
