Derek Parfit (1942–2017) is the most famous philosopher most people have never heard of. Widely regarded as one of the greatest moral thinkers of the past hundred years, Parfit was anything but a public intellectual. Yet his ideas have shaped the way philosophers think about things that affect us all: equality, altruism, what we owe to future generations, and even what it means to be a person. In Parfit, David Edmonds presents the first biography of an intriguing, obsessive, and eccentric genius.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on 20th-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A. C. Grayling makes Wittgenstein's thought accessible to the general listener by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.

Nearly a hundred years after its publication, Kurt Gödel's famous proof that every mathematical system must contain propositions that are true - yet never provable - continues to unsettle mathematics, philosophy, and computer science. Yet unlike Einstein, with whom he formed a warm and abiding friendship, Gödel has long escaped all but the most casual scrutiny of his life.

In a career spanning 60 years, Sir Karl Popper has made some of the most important contributions to the 20th century discussion of science and rationality. The Myth of the Framework is a collection of some of Popper's most important material on this subject.

Conjectures and Refutations is one of Karl Popper’s most wide-ranging and popular works, notable not only for its acute insights into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge but our aims and our standards grow through an unending process of trial and error.

The history of European philosophy is usually constructed from the work of men. In Metaphysical Animals, a pioneering group biography, Clare Mac Cumhaill and Rachael Wiseman offer a compelling alternative. In the mid-twentieth century Elizabeth Anscombe, Mary Midgley, Philippa Foot, and Iris Murdoch were philosophy students at Oxford when most male undergraduates and many tutors were conscripted away to fight in the Second World War. Together, these young women, all friends, developed a philosophy that could respond to the war’s darkest revelations.

As Elizabeth Anscombe, Philippa Foot, Mary Midgley, and Iris Murdoch labored to make a place for themselves in a male-dominated world, as they made friendships and families, and as they drifted toward and away from each other, they never stopped insisting that some lives are better than others. Drawing on a cluster of recently opened archives and extensive correspondence and interviews with those who knew them best, Benjamin Lipscomb traces the lives and ideas of four friends who gave us a better way to think about ethics, and ourselves.

These were among the questions that philosophers wrestled with in mid-twentieth-century Britain, a period shadowed by war and the rise of fascism. In response to these events, thinkers such as Philippa Foot (originator of the famous trolley problem), Isaiah Berlin, Iris Murdoch, Elizabeth Anscombe, Gilbert Ryle, and J. L. Austin aspired to a new level of watchfulness and self-awareness about language as a way of keeping philosophy true to everyday experience.

All Life is Problem Solving is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life. This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War and after the collapse of communism.

Why we think it’s a great listen: You thought he was a stodgy scientist with funny hair, but Isaacson and Hermann reveal an eloquent, intense, and selfless human being who not only shaped science with his theories, but politics and world events in the 20th century as well. Based on the newly released personal letters of Albert Einstein, Walter Isaacson explores how an imaginative, impertinent patent clerk became the mind reader of the creator of the cosmos.

The year is 1919. The horror of the First World War is fresh for the protagonists of Time of the Magicians, each of whom finds himself at a crucial juncture. Benjamin is trying to flee his overbearing father and floundering in his academic career, living hand to mouth as a critic. Wittgenstein, by contrast, has dramatically decided to divest himself of the monumental fortune he stands to inherit, in search of spiritual clarity.

Many academics attack the very idea of a Western canon as chauvinistic, while the general public increasingly doubts the value of the humanities. In Rescuing Socrates, Dominican-born American academic Roosevelt Montás tells the story of how a liberal education transformed his life, and offers an intimate account of the relevance of the Great Books today, especially to members of historically marginalized communities.

Both a history and an examination of human thought and behavior spanning three thousand years, On Politics thrillingly traces the origins of political philosophy from the ancient Greeks to Machiavelli in Book I and from Hobbes to the present age in Book II. Whether examining Lord Acton's dictum that "absolute power corrupts absolutely" or explicating John Stuart Mill's contention that it is "better to be a human dissatisfied than a pig satisfied," Alan Ryan evokes the lives and minds of our greatest thinkers in a way that makes hearing about them a transcendent experience.

Martin Heidegger's sympathies for the conservative revolution and National Socialism have long been well known. As the rector of the University of Freiburg in the early 1930s, he worked hard to reshape the university in accordance with National Socialist policies. He also engaged in an all-out struggle to become the movement's philosophical preceptor, "to lead the leader." Yet for years, Heidegger's defenders have tried to separate his political beliefs from his philosophical doctrines

Hardly a club in the conventional sense, the organization referred to in the title of this superb literary hybrid (part history, part biography, part philosophy) consisted of four members and probably existed for less than nine months.

Few historians end up as historical actors in their own right, but Bernard Lewis has both witnessed and participated in some of the key events of the last century. When we think of the Middle East, we see it in terms that he defined and articulated.In this exceptional memoir he shares stories of his wartime service in London and Cairo, decrypting intercepts for MI6, with sometimes unexpected consequences. After the war, he was the first Western scholar ever invited into the Ottoman archives in Istanbul.

Burns highlights the two facets of Rand's work that make her a perennial draw for those on the right: Her promotion of capitalism, and her defense of limited government. Both sprang from her early, bitter experience of life under Communism, and became among the most deeply enduring of her messages, attracting a diverse audience of college students and intellectuals, business people and Republican Party activists, libertarians and conservatives.

Robert Oppenheimer was among the most brilliant and divisive of men. As head of the Los Alamos Laboratory, he oversaw the successful effort to beat the Nazis in the race to develop the first atomic bomb – a breakthrough that was to have eternal ramifications for mankind and that made Oppenheimer the “Father of the Atomic Bomb.” But with his actions leading up to that great achievement, he also set himself on a dangerous collision course with Senator Joseph McCarthy and his witch-hunters. In Robert Oppenheimer: A Life Inside the Center, Ray Monk, author of peerless biographies of Ludwig Wittgenstein and Bertrand Russell, goes deeper than any previous biographer in the quest to solve the enigma of Oppenheimer’s motivations and his complex personality.

Jean-Paul Sartre is one of the undisputed giants of 20th-century philosophy. His intellectual writings popularizing existentialism, combined with his creative and artistic flair, have made him a legend of French thought. His tumultuous personal life - so inextricably bound up with his philosophical thinking - is a fascinating tale of love and lust, drug abuse, high-profile fallings-out and political and cultural rebellion.

In honor of the 50th anniversary of C. S. Lewis' death, celebrated Oxford don Dr. Alister McGrath presents us with a compelling and definitive portrait of the life of C. S. Lewis, the author of the well-known Narnia series. For more than half a century, C. S. Lewis’ Narnia series has captured the imaginations of millions. In C. S. Lewis - A Life, Dr. Alister McGrath recounts the unlikely path of this Oxford don, who spent his days teaching English literature to the brightest students in the world and his spare time writing.

Paris, 1933: Three contemporaries meet over apricot cocktails at the Bec-de-Gaz bar on the rue Montparnasse. They are the young Jean-Paul Sartre, Simone de Beauvoir, and longtime friend Raymond Aron, a fellow philosopher who raves to them about a new conceptual framework from Berlin called phenomenology. "You see," he says, "if you are a phenomenologist, you can talk about this cocktail and make philosophy out of it!"

There are many stories we can spin about previous ages, but which accounts get told? And by whom? Is there even such a thing as “objective” history? In this “witty, wise, and elegant” (The Spectator), book, Richard Cohen reveals how professional historians and other equally significant witnesses, such as the writers of the Bible, novelists, and political propagandists, influence what becomes the accepted record. Cohen argues, for example, that some historians are practitioners of “Bad History” and twist reality to glorify themselves or their country.

Friedrich Engels is one of the most intriguing and contradictory figures of the 19th century. Born to a prosperous Prussian mercantile family, he spent his life working in the Manchester cotton industry, riding to the Cheshire hounds, and enjoying the comfortable upper-middle-class existence of a Victorian gentleman.

Returning Marx to the Victorian confines of the 19th century, Jonathan Sperber, one of the United States' leading European historians, challenges many of our misconceptions of this political firebrand turned London journalist. In this deeply humanizing portrait, Marx no longer is the Olympian soothsayer, divining the dialectical imperatives of human history, but a scholar-activist whose revolutionary Weltanschauung was closer to Robespierre's than to those of 20th-century Marxists.

Paul Dirac was among the great scientific geniuses of the modern age. One of the discoverers of quantum mechanics, the most revolutionary theory of the past century, his contributions had a unique insight, eloquence, clarity, and mathematical power. His prediction of antimatter was one of the greatest triumphs in the history of physics.

In My Battle against Hitler, von Hildebrand tells of the scorn and ridicule he endured for sounding the alarm when many still viewed Hitler as a positive and inevitable force. He tells how he defiantly challenged Nazism in the public square, prompting the German ambassador in Vienna to describe him to Hitler as "the architect of the intellectual resistance."

Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime.

In this collection of essays, Walter Isaacson reflects on the lessons to be learned from Benjamin Franklin, Albert Einstein, Bill Gates, Henry Kissinger, Ronald Reagan and Mikhail Gorbachev, Hillary Clinton and Bill Clinton, and various other interesting characters he has chronicled as a biographer and journalist. The people he writes about have an awesome intelligence, in most cases, but that is not the secret of their success.

From his modest headquarters in Crown Heights, Brooklyn, the Rebbe advised some of the world's greatest leaders and shaped matters of state and society. Statesmen and artists as diverse as Ronald Reagan, Robert F. Kennedy, Yitzchak Rabin, Menachem Begin, Elie Wiesel, and Bob Dylan span the spectrum of those who sought his counsel.

Inspired by Albert Einstein's theory of relativity and Bertrand Russell and David Hilbert's pursuit of the fundamental rules of mathematics, some of the most brilliant minds of the generation came together in post-World War I Vienna to present the latest theories in mathematics, science, and philosophy and to build a strong foundation for scientific investigation. Composed of such luminaries as Kurt Gödel and Rudolf Carnap, and stimulated by the works of Ludwig Wittgenstein and Karl Popper, the Vienna Circle left an indelible mark on science.

Probing the life and work of Kurt Gödel, Incompleteness indelibly portrays the tortured genius whose vision rocked the stability of mathematical reasoning—and brought him to the edge of madness.

This lively and accessible introduction to Plato focuses on the philosophy and argument of his writings, drawing the listener into Plato's way of doing philosophy, and the general themes of his thinking. It looks at Plato as a thinker grappling with philosophical problems in a variety of ways, rather than a philosopher with a fully worked-out system. It includes a brief account of Plato's life and the various interpretations that have been drawn from the sparse remains of information.

In Significant Figures, acclaimed mathematician Ian Stewart introduces the visionaries of mathematics throughout history. Delving into the lives of twenty-five great mathematicians, Stewart examines the roles they played in creating, inventing, and discovering the mathematics we use today. Through these short biographies, we get acquainted with the history of mathematics.

The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

Nearly a hundred years after its publication, Kurt Gödel's famous proof that every mathematical system must contain propositions that are true - yet never provable - continues to unsettle mathematics, philosophy, and computer science. Yet unlike Einstein, with whom he formed a warm and abiding friendship, Gödel has long escaped all but the most casual scrutiny of his life.

The Sleepwalkers: How Europe Went to War in 1914 is historian Christopher Clark’s riveting account of the explosive beginnings of World War I. Drawing on new scholarship, Clark offers a fresh look at World War I, focusing not on the battles and atrocities of the war itself, but on the complex events and relationships that led a group of well-meaning leaders into brutal conflict.
