Rene Descartes spent most of his childhood in solitude, a situation that also came to characterize his adult life. Fortunately, these countless lonely hours helped Descartes produce the declaration that changed all philosophy: "I think, therefore I am." Eventually convincing himself to doubt and disregard sensory knowledge, Descartes found he could prove his existence through his thoughts. This internal information, he believed, was the true reality and external forces were hopelessly deceiving.

Kierkegaard wasn't really a philosopher in the academic sense. Yet he produced what many people expect of philosophy. His subject was the individual and his or her existence, the "existing being." In Kierkegaard's view, this purely subjective entity lay beyond the reach of reason, logic, philosophical systems, theology, or even "the pretenses of psychology." Nonetheless, it was the source of all these subjects. The branch of philosophy to which Kierkegaard gave birth has come to be known as existentialism.

In an age when philosophers had scarcely glimpsed the horizons of the mind, a boy named Aristocles decided to forgo his ambitions as a wrestler. Adopting the nickname Plato, he embarked instead on a life in philosophy. In 387 B.C. he founded the Academy, the world's first university, and taught his students that all we see is not reality but merely a reproduction of the true source. And in his famous Republic he described the politics of "the highest form of state."

Aristotle wrote on everything from the shape of seashells to sterility, from speculations on the nature of the soul to meteorology, poetry, art, and even the interpretation of dreams. Apart from mathematics, he transformed every field of knowledge that he touched. Above all, Aristotle is credited with the founding of logic. When he first divided human knowledge into separate categories, he enabled our understanding of the world to develop in a systematic fashion.

With Hegel, philosophy became very difficult indeed. His dialectical method produced the most grandiose metaphysical system known to man. Even Hegel conceded that "only one man understands me, and even he does not." Hegel's system included absolutely everything, but its most vital element was the dialectic of the thesis, antithesis, and synthesis. This method sprang from Hegel's ambition to overcome the deficiencies of logic and ascended toward mind as the ultimate reality.

Just a century after it had begun, philosophy entered its greatest age with the appearance of Socrates, who spent so much of his time talking about philosophy on the streets of Athens that he never got around to writing anything down. His method of aggressive questioning, called dialectic, was the forerunner of logic; he used it to cut through the twaddle of his adversaries and arrive at the truth. Rather than questioning the world, he believed, we would be better off questioning ourselves.

One of the two major philosophical traditions of the twentieth century was linguistic analysis, derived largely from Wittgenstein. The other, diametrically opposed, came from Heidegger, and its fundamental question was, "What is the meaning of existence?" For Heidegger, this question could not simply be "analyzed away". It was beyond the reach of logic or reason. It was the primary "given" of every individual life. To confront it, Heidegger needed to develop an entire new form of philosophy.

Confucius knew all about life and told us how to behave, but we can't find out precisely what he was up to. His well-meaning platitudes, quaint maxims, and quasi-enigmatic anecdotes combined to produce an ideal philosophy for civil servants. It would appear that his aim was to turn his pupils into good government officials, but his teachings succeeded beyond his wildest expectations, providing rules of conduct and spiritual fodder for more than two thousand years.

In Rousseau we encounter a walking ego, naked sensibility. Feeling triumphs over intellectual argument in his works, which are both deeply stirring and deeply inconsistent. Yet while his contemporaries Kant and Hume may have been superior academic philosophers, the sheer power of Rousseau's ideas was unequaled in his time. It was he who encouraged the introduction of both liberty and irrationality into the public domain.

Spinoza's brilliant metaphysical system was derived neither from reality nor experience. Starting from basic assumptions, with a series of geometric proofs he built a universe which was also God, one and the same thing, the classic example of pantheism. Although his system seems an oddity today, Spinoza's conclusions are deeply in accord with modern thought, from science (the holistic ethics of today's ecologists) to politics (the idea that the state exists to protect the individual).

During his lifetime, Jean-Paul Sartre enjoyed unprecedented popularity for a philosopher, due partly to his role as a spokesman for existentialism at the opportune moment, when this set of ideas filled the spiritual gap left amidst the ruins of World War II. Existentialism was a philosophy of action and showed the ultimate freedom of the individual. In Sartre's hands, it became a revolt against European bourgeois values.

David Hume reduced philosophy to ruins: he denied the existence of everything, except our actual perceptions themselves. I alone exist, he argued, and the world is nothing more than part of my consciousness. Yet we know that the world remains, and we go on as before. What Hume expressed was the status of our knowledge about the world, a world in which neither religion nor science is certain.

Karl Marx's devastating critique of capitalism, and his proposal of communism as the answer to the failings of the capitalist system, bore their greatest fruits in the twentieth century with the formation of the communist state in the Soviet Union. This great venture has now all but completely failed. Yet the force of the communist belief offered the prospect of "justice on this earth" to countless numbers. And Marx's critique has influenced generations of thinkers who call themselves Marxists.

After narrowly avoiding a firing squad when he was just twenty-eight years old, Dostoevsky never took things lightly. His great novels burst upon the European literary scene like a succession of thunderbolts. His understanding of the darker and more extreme recesses of the human mind cast a forceful light into these areas of experience. The raw psychology and passionate involvement of his books galvanized writers and thinkers as disparate as Nietzsche and Kafka.

The 13 chapters of The Art of War, each devoted to one aspect of warfare, were compiled by the high-ranking Chinese military general, strategist, and philosopher Sun-Tzu. In spite of its battlefield specificity, The Art of War has found new life in the modern age, with leaders in fields as wide and far-reaching as world politics, human psychology, and corporate strategy finding valuable insight in its timeworn words.

Why have history's greatest minds - from George Washington to Frederick the Great to Ralph Waldo Emerson along with today's top performers, from Super Bowl-winning football coaches to CEOs and celebrities - embraced the wisdom of the ancient Stoics? Because they realize that the most valuable wisdom is timeless and that philosophy is for living a better life, not a classroom exercise. The Daily Stoic offers a daily devotional of Stoic insights and exercises, featuring all-new translations.

Christmas is the single biggest annual event on the planet, a time for merry-making, over-indulgence, peace, goodwill, and the occasional family row. It’s as comfortable and familiar as a pair of old shoes and yet still glittery and exciting. But what do you really know about it? It’s stuffed full of traditions and rituals that most of us have been observing all our lives without having the slightest idea of where they come from.

Will Johnnie Veal—convicted of the murder of two police officers in 1970—be granted parole after 50 years in prison? How can he convince the parole board he’s reformed when he insists he’s innocent? What is prison time even supposed to accomplish? These are the questions that propel The Parole Room forward as it builds toward Johnnie’s 20th parole hearing—after 19 rejections.

The ancient Toltecs believed that life, as we perceive it, is a dream. We each live in our own personal dream, and these come together to form the dream of the planet, or the world in which we live. Problems arise when our perception of the dream becomes clouded with negativity, drama, and judgment (of ourselves and others), because it's in these moments of suffering that we have forgotten that we are the architects of our own reality and we have the power to change our dream if we choose.

I have discovered a group of women who refuse to be exploited, are immune to manipulation, and who never settle in the name of love. These ladies know what they want and take what they want by beating men at their own game. Utilizing the secrets exposed in this book, these women gain power, money, and status. Men call them gold diggers, women call them hos, but they call themselves winners. This is the book that society doesn't want you to listen to….

Experience a bold take on this classic autobiography as it’s performed by Oscar-nominated Laurence Fishburne. In this searing classic autobiography, originally published in 1965, Malcolm X, the Muslim leader, firebrand, and Black empowerment activist, tells the extraordinary story of his life and the growth of the Human Rights movement. His fascinating perspective on the lies and limitations of the American dream and the inherent racism in a society that denies its non-White citizens the opportunity to dream, gives extraordinary insight into the most urgent issues of our own time.

Based on seven years of ground-breaking research and hundreds of interviews, I Thought It Was Just Me shines a long-overdue light on an important truth: Our imperfections are what connect us to each other and to our humanity. Our vulnerabilities are not weaknesses; they are powerful reminders to keep our hearts and minds open to the reality that we're all in this together.

Immanuel Kant taught and wrote prolifically about physical geography yet never traveled further than forty miles from his home in Kvnigsberg. How appropriate it is then that in his philosophy he should deny that all knowledge was derived from experience. He insisted that all experience must conform to knowledge. According to Kant, space and time are subjective; along with various "categories," they help us to see the phenomena of the world, though never its true reality.

Aristotle wrote on everything from the shape of seashells to sterility, from speculations on the nature of the soul to meteorology, poetry, art, and even the interpretation of dreams.

Schopenhauer, the "philosopher of pessimism", makes it very plain that he regards the world and our life in it as a bad joke. But if the world is indifferent to our fate, it doesn't thwart us on purpose. The world's facade is supported by what Schopenhauer calls the Universal Will, blind and without purpose. This Will brings on all our misery and suffering; our only hope is to liberate ourselves from its power and from the trappings of individualism and egoism that are at its mercy.

We see our age as the greatest in human history, filled with seemingly unending originality. Yet such dynamism is not a necessary characteristic of great eras. Among the most long-lasting and stable civilizations was that of medieval Europe. There stasis was achieved, and with it a stability that permitted the development of structured thought and intellectual embellishment of unparalleled degree.

"If we accept Wittgenstein's word for it," Paul Strathern writes, "he is the last philosopher. In his view, philosophy in the traditional sense was finished."
