Modern Philosophy

Born a slave, the Roman Stoic philosopher Epictetus (c. 55-135 AD) taught that mental freedom is supreme, since it can liberate one anywhere, even in a prison. In How to Be Free, A. A. Long - one of the world's leading authorities on Stoicism and a pioneer in its remarkable contemporary revival - provides a superb new edition of Epictetus's celebrated guide to the Stoic philosophy of life (the Encheiridion) along with a selection of related reflections in his Discourses.

Nearly six hundred years ago, a short, genial, cannily alert man in his late 30s took a very old manuscript off a library shelf, saw with excitement what he had discovered, and ordered that it be copied. That book was the last surviving manuscript of an ancient Roman philosophical epic by Lucretius—a beautiful poem containing the most dangerous ideas: that the universe functioned without the aid of gods, that religious fear was damaging to human life, and that matter was made up of very small particles.

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.

Worried that old age will inevitably mean losing your libido, your health, and possibly your marbles too? Well, Cicero has some good news for you. In How to Grow Old, the great Roman orator and statesman eloquently describes how you can make the second half of life the best part of all - and why you might discover that reading and gardening are actually far more pleasurable than sex ever was.

With Friedrich Nietzsche, philosophy was dangerous not only for philosophers but for everyone. His ideas presaged a collective madness that had horrific consequences in Europe in the early 1900s. Though his philosophy is more one of aphorisms than a system, it is brilliant, persuasive, and incisive. His major concept is the will to power, which he saw as the basic impulse for all our acts. Christianity he saw as a subtle perversion of this concept, thus Nietzsche's famous pronouncement, "God is dead."

Once solely the province of ivory-tower professors and college classrooms, contemporary philosophy was finally emancipated from its academic closet in 2010, when "The Stone" was launched in The New York Times. First appearing as an online series, the column quickly attracted millions of readers through its accessible examination of universal topics like the nature of science, consciousness, and morality while also probing more contemporary issues such as the morality of drones, gun control, and the gender divide.

The final and most personal work from Pulitzer Prize - winning author and historian Will Durant - discovered 32 years after his death - is a message of insight for everyone who has sought meaning in life or the council of a wise friend in navigating life's journey. From 1968 to 1978, Will Durant made four public allusions to the existence of Fallen Leaves. One, in 1975, hinted at its contents: "a not very serious book that answers the questions of what I think about government, life, death, and God."

Code of the Samurai is a 400-year-old explication of the rules and expectations embodied in Bushido, the Japanese Way of the Warrior. With a bright, conversational narrative by Thomas Cleary, this book is indispensable to corporate executives, students of Asian culture, martial artists, or anyone sincerely interested in Japan and its people.

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.

All of us are faced countless times with the challenge of persuading others, whether we're trying to win a trivial argument with a friend or convince our coworkers about an important decision. Instead of relying on untrained instinct - and often failing as a result - we'd win more arguments if we learned the timeless art of verbal persuasion, or rhetoric.

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.

In a world where social media, online relationships, and relentless self-absorption threaten the very idea of deep and lasting friendships, the search for true friends is more important than ever. In this short book, famous Roman politician and philosopher Cicero offers a compelling guide to finding, keeping, and appreciating friends. With wit and wisdom, Cicero teaches not only how to build friendships but also why they must be a key part of our lives. For, as Cicero says, life without friends is not worth living.

Richard M. Weaver argues that the decline of Western civilization resulted from the rising acceptance of relativism over absolute reality. In spite of increased knowledge, this retreat from the realist intellectual tradition has weakened the Western capacity to reason, with catastrophic consequences for social order and individual rights. But Weaver also offers a realistic remedy. These difficulties are the product not of necessity, but of intelligent choice.

Evil threatens human reason, for it challenges our hope that the world makes sense. For 18th-century Europeans, the Lisbon earthquake was manifest evil. Today we view evil as a matter of human cruelty, and Auschwitz as its extreme incarnation. Examining our understanding of evil from the Inquisition to contemporary terrorism, Susan Neiman explores who we have become in the three centuries that separate us from the early Enlightenment. In the process, she rewrites the history of modern thought and points philosophy back to the questions that originally animated it.

For nearly 2,500 years, students, politicians, political thinkers, and military leaders have read the eloquent and shrewd speeches in Thucydides' History of the Peloponnesian War for profound insights into military conflict, diplomacy, and the behavior of people and countries in times of crisis. How to Think about War presents the most influential and compelling of these speeches in an elegant new translation by classicist Johanna Hanink, accompanied by an enlightening introduction.

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.

The ancient biographer and essayist Plutarch thought deeply about the leadership qualities of the eminent Greeks and Romans he profiled in his famous - and massive - Lives, including politicians and generals such as Pericles, Alexander the Great, Julius Caesar, and Mark Antony. Luckily for us, Plutarch distilled what he learned about wise leadership in a handful of essays, which are filled with essential lessons for experienced and aspiring leaders in any field today.

This book gives a clear overview of the philosophical work of Jürgen Habermas, the most influential German philosopher alive today, who has commented widely on subjects such as Marxism, the importance and effectiveness of communication, the reunification of Germany, and the European Union. Gordon Finlayson provides listeners with a clear overview of Habermas's forbiddingly complex philosophy using concrete examples and accessible language.

Can jokes win a hostile room, a hopeless argument, or even an election? You bet they can, according to Cicero, and he knew what he was talking about. One of Rome's greatest politicians, speakers, and lawyers, Cicero was also reputedly one of antiquity's funniest people. After he was elected commander-in-chief and head of state, his enemies even started calling him "the stand-up Consul". How to Tell a Joke provides a lively new translation of Cicero's essential writing on humor alongside that of the later Roman orator and educator Quintilian.
