As news reports of the horrific December 2004 tsunami in Asia reached the rest of the world, commentators were quick to seize upon the disaster as proof of either God’s power or God’s nonexistence, asking over and over, How could a good and loving God - if such exists - allow such suffering? In The Doors of the Sea, David Bentley Hart speaks at once to those skeptical of Christian faith and to those who use their Christian faith to rationalize senseless human suffering.

As intriguing today as when it was first published, Hume's An Enquiry Concerning Human Understanding is a fascinating exploration into the nature of human knowledge. Using billiard balls, candles, and other colorful examples, Hume conveys the core of his empiricism - that true knowledge can be gained only through sensory experience.

A Treatise of Human Nature is the first work ever published by David Hume, a man who revolutionized our understanding of philosophy. Hume was an advocate of the skeptical school of philosophy and a key figure in the Scottish Enlightenment. He looks at the nature of human experience and cognition, showing that philosophy and reason can only be reflections of our nature.

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.

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 Tractatus Logico-Philosophicus (Logical Philosophical Treatise or Treatise on Logic and Philosophy) is the only full-length philosophical book by the Austrian philosopher Ludwig Wittgenstein that was published during his lifetime. The goal of the work is to identify the relationship between language and reality and to define the limits of science. He famously summarized the book in the following way: "What can be said at all can be said clearly; and what we cannot talk about we must pass over in silence."

King Leontes of Sicilia is seized by sudden and terrible jealousy of his wife Hermione, whom he accuses of adultery. He believes the child Hermione is bearing was fathered by his friend Polixenes, and when the baby girl is born he orders her to be taken to some wild place and left to die. Though Hermione's child escapes death, Leontes' cruelty has terrible consequences. Loss paves the way for reunion, and life and hope are born out of desolation and despair.

Russell once said, "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric." His views on religion in general, and on Christianity in particular (as in this work), were considered "eccentric" by many of his contemporaries. So were his views on sex, which figures frequently as an example of the misery that Christian leaders and thinkers inflict, and for which he was often vilified. The lectures in this collection leave no doubt about his views on these and related subjects.

This extraordinary work (Das Wesen Des Christentums) is an anthropological dissection of Christianity in particular and a critique of religion in general. It proved both controversial and influential following its publication in 1841. But soon it became a classic of humanism - so much so that it was none other than George Eliot, under her real name of Marian (Mary Ann) Evans, who felt impelled to undertake the first English translation (1851), and which helped to underscore her humanistic attitudes which infused her novels.

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

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?

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".

Christopher Hitchens continues to make the case for a splendidly godless universe in this first-ever gathering of the influential voices past and present that have shaped his side of the current (and raging) God/no-god debate. With Hitchens as your erudite and witty guide, you'll be led through a wealth of philosophy, literature, and scientific inquiry, including generous portions of the words of Lucretius, Benedict de Spinoza, Charles Darwin, Karl Marx, Mark Twain, and more.

"The central miracle asserted by Christians is the Incarnation. They say that God became Man. Every other miracle prepares the way for this, or results from this." This is the key statement of Miracles, in which C. S. Lewis shows that a Christian must not only accept but rejoice in miracles as a testimony of the unique personal involvement of God in his creation.

There is a cause, or a reason, behind everything that happens. This is the fundamental view behind the classical proposition the Principle of Sufficient Reason, which, in 1813, Schopenhauer chose as his subject for further examination in his doctoral dissertation On the Fourfold Root of the Principle of Sufficient Reason....

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.

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.

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.

Considered by many to be Hannah Arendt's greatest work, published as she neared the end of her life, The Life of the Mind investigates thought itself, as it exists in contemplative life. In a shift from her previous writings, most of which focus on the world outside the mind, this work was planned as three volumes that would explore the activities of the mind considered by Arendt to be fundamental. What emerged is a rich, challenging analysis of human mental activity, considered in terms of thinking, willing, and judging.

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.

Where did the ideas come from that became the cornerstone of American democracy? Not only the erudite Thomas Jefferson, the wily and elusive Ben Franklin, and the underappreciated Thomas Paine, but also Ethan Allen, the hero of the Green Mountain Boys, and Thomas Young, the forgotten Founder who kicked off the Boston Tea Party. These radicals who founded America set their sights on a revolution of the mind. Derided as "infidels" and "atheists" in their own time, they wanted to liberate us not just from one king but from the tyranny of supernatural religion.

Socrates is in prison, sentenced to die when the sun sets. In this final conversation, he asks what will become of him once he drinks the poison prescribed for his execution. Socrates and his friends examine several arguments designed to prove that the soul is immortal. This quest leads him to the broader topic of the nature of mind and its connection not only to human existence but also to the cosmos itself. What could be a better way to pass the time between now and the sunset?

Christopher Hitchens continues to make the case for a splendidly godless universe in this first-ever gathering of the influential voices past and present that have shaped his side of the current (and raging) God/no-god debate. With Hitchens as your erudite and witty guide, you'll be led through a wealth of philosophy, literature, and scientific inquiry, including generous portions of the words of Lucretius, Benedict de Spinoza, Charles Darwin, Karl Marx, Mark Twain, and more.

A dialogue between Socrates and Meno probes the subject of ethics. Can goodness be taught? If it can, then we should be able to find teachers capable of instructing others about what is good and bad, right and wrong, or just and unjust.

'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.

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.

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.

"The central miracle asserted by Christians is the Incarnation. They say that God became Man. Every other miracle prepares the way for this, or results from this." This is the key statement of Miracles, in which C. S. Lewis shows that a Christian must not only accept but rejoice in miracles as a testimony of the unique personal involvement of God in his creation.

One of our most renowned and brilliant historians takes a fresh look at the revolutionary intellectual movement that laid the foundation for the modern world. Liberty and equality. Human rights. Freedom of thought and expression. Belief in reason and progress. The value of scientific inquiry. These are just some of the ideas that were conceived and developed during the Enlightenment, and which changed forever the intellectual landscape of the Western world.

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.
