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.

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.

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.

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.

Published in 1748, An Enquiry Concerning Human Understanding is Scottish empiricist philosopher David Hume's distillation of his mature philosophy. Addressing themes including the limits of human understanding, the compatibility of free will with determinism, weaknesses in the foundations of religion, and the appeal of skepticism, An Enquiry Concerning Human Understanding is Hume's attempt to revise and clarify the ideas of his earlier A Treatise of Human Nature.

Aristotle's Poetics is best known for its definitions and analyses of tragedy and comedy, but it also applies to truth and beauty as they are manifested in the other arts. In our age, when the natural and social sciences have dominated the quest for truth, it is helpful to consider why Aristotle claimed poetry is more philosophical and more significant than history. Like so many other works by Aristotle, the Poetics has dominated the way we have thought about all forms of dramatic performance in Europe and America ever since.

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?

In On the Genealogy of Morals, subtitled "A Polemic", Nietzsche furthers his pursuit of a clarity that is less tainted by imposed prejudices. He looks at the way attitudes towards 'morality' evolved and the way congenital ideas of morality were heavily colored by the Judaic and Christian traditions.

Murray Rothbard was known as the state's greatest living enemy, and this audiobook is his most powerful statement on the topic. He explains what a state is and what it is not. He shows how it is an institution that violates all that we hold as honest and moral, and how it operates under a false cover.

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.

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.

Loving Life demonstrates that morality is not a matter of divine revelation nor social convention nor personal opinion but a matter of the factual requirements of human life and personal happiness. Biddle shows how a true morality is derived logically from observable facts, what in essence such a morality demands, and why it is a matter of pure self-interest.

In this book, which the author calls a "culmination of 30 years of work in the history of ideas", Sowell attempts to explain the ideological difference between liberals and conservatives as a disagreement over the moral potential inherent in nature. Those who see that potential as limited prefer to constrain governmental authority, he argues. They feel that reform is difficult and often dangerous, and put their faith in family, custom, law, and traditional institutions.

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.

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.

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.

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.

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.

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.

Who needs philosophy? Ayn Rand's answer: Everyone. This collection of essays was the last work planned by Ayn Rand before her death in 1982. In it, she summarizes her view of philosophy and deals with a broad spectrum of topics. According to Ayn Rand, the choice we make is not whether to have a philosophy, but which one to have: a rational, conscious, and therefore practical one, or a contradictory, unidentified, and ultimately lethal one.

"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)."

lf a man cannot stand freedom, he will probably turn fascist. This, in the fewest possible words, is the essential argument in this modem classic, Escape from Freedom. The author, Erich Fromm, is a distinguished psychologist, late of Berlin and Heidelberg, now of New York City.

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.

What does it mean to be truthful? What role does truth play in our lives? What do we lose if we reject truthfulness? No philosopher is better suited to answer these questions than Bernard Williams. Writing with his characteristic combinationof passion and elegant simplicity, he explores the value of truth and finds it to be both less and more than we might imagine.

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.

What are the arguments for and against religion and religious belief - all of them - right across the range of reasons and motives that people have for being religious, and do they stand up to scrutiny? Can there be a clear, full statement of these arguments that once and for all will show what is at stake in this debate? Equally important: what is the alternative to religion as a view of the world and a foundation for morality?

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.

As Douglas Adams points out, if there is no final answer to the question "what is the meaning of life?" 42 is as good or bad an answer as any other. Indeed, 42 quotes might be even better! Gary Cox guides us through 42 of the most misunderstood, misquoted, provocative, and significant quotes in the history of philosophy, providing witty and compelling commentary along the way.
