The Sunday Times Number One Bestseller. Over 10 million copies sold around the world. The original book from Morgan Housel, the New York Times and Sunday Times bestselling author of Same As Ever and The Art of Spending Money. As featured on the Dr Chatterjee podcast Feel Better, Live More and The Diary of a CEO podcast with Steven Bartlett. Doing well with money isn't necessarily about what you know. It's about how you behave. And behavior is hard to teach, even to really smart people. Money – investing, personal finance, and business decisions – is typically taught as a math-based field, where data and formulas tell us exactly what to do. But in the real world people don't make financial decisions on a spreadsheet. They make them at the dinner table, or in a meeting room, where personal history, your own unique view of the world, ego, pride, marketing, and odd incentives are scrambled together. In The Psychology of Money, award-winning author Morgan Housel shares 19 short stories exploring the strange ways people think about money and teaches you how to make better sense of one of life's most important topics.
The most precise and authoritative translation of one of the founding works of Western culture, in an edition supported by helpful, effective notes The Nicomachean Ethics is one of Aristotle’s most widely read and influential works. Ideas central to ethics—that happiness is the end of human endeavor, that moral virtue is formed through action and habituation, and that good action requires prudence—found their most powerful proponent in the person medieval scholars simply called “the Philosopher.” Drawing on their intimate knowledge of Aristotle’s thought, Robert C. Bartlett and Susan D. Collins have produced here an English-language translation of the Ethics that is as remarkably faithful to the original as it is graceful in its rendering. Aristotle is well known for the precision with which he chooses his words, and in this elegant translation his work has found its ideal match. Bartlett and Collins provide copious notes and a glossary providing context and further explanation for students, as well as an introduction and a substantial interpretive essay that sketch central arguments of the work and the seminal place of Aristotle’s Ethics in his political philosophy as a whole. The Nicomachean Ethics has engaged the serious interest of readers across centuries and civilizations—of peoples ancient, medieval, and modern; pagan, Christian, Muslim, and Jewish—and this new edition will take its place as the standard English-language translation.

What is at the core of the Israeli-Palestinian conflict? What does justice demand of us in this conflict? This book clarifies an intimidatingly complex issue—and upends conventional views about America’s stake in it. In this book, Elan Journo explains the essential nature of the conflict, and what has fueled it for so long. What justice demands, he shows, is that we evaluate both adversaries—and America's approach to the conflict—according to a universal moral ideal: individual liberty. From that secular moral framework, the book analyzes the conflict, examines major Palestinian grievances and Israel's character as a nation, and explains what's at stake for everyone who values human life, freedom, and progress. What Justice Demands shows us why America should be strongly supportive of freedom and freedom-seekers—but, in this conflict and across the Middle East, it hasn't been, much to our detriment.
The panic of 1819 was America's first great economic crisis. And this is Murray Rothbard's masterful account, the first full scholarly book on the topic and still the most definitive. It was his dissertation, published in 1962 but nearly impossible to get until this new edition.The American Economic Review was wild for this book when it appeared: "Rothbard's work represents the only published, book-length, academic treatise on the remedies that were proposed, debated, and enacted in attempts to cope with the crisis of 1819," the reviewer wrote. "As such, the book should certainly find a place on the shelf of the study of U.S. business cycles and of the economic historian who is interested in the early economic development of the United States."And specialists have treasured the book for years. It is incredible to realize that some American historians think of M.N. Rothbard as the author of this book and nothing else!The panic of 1819 grew largely out of the changes wrought by the War of 1812, and by the postwar boom that followed. The war also brought a rash of paper money, as the government borrowed heavily to finance the conflict. This would inevitably lead to suspension of specie payments in some parts of the country in 1814.Freed from the shackles of hard money, the suspension of specie led to a boom. When peace came, the so did the bust.But in the end, there was no widespread confusion on what caused the downturn. Instead, it was widely known that false prosperity is a very dangerous thing. It always turns to bust. But unlike today, the government didn't intervene. And precisely because there was no intervention, the panic ended quickly and peacefully.What we have here, then, is not only a dazzling historical account — the research here is deep and thorough, and the prose a model of exposition; it also points the way to how all economic downturns can and should be handled. For that reason, the Panic of 1819 offers important lessons for us today.To search for Mises Institute titles, enter a keyword and LvMI (short for Ludwig von Mises Institute); e.g., Depression LvMI
In this "provocative" book (New York Times), a contrarian physicist argues that her field's modern obsession with beauty has given us wonderful math but bad science. Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth.
