Published in 1963, this book about the famous accountant and bookkeeper Luca Paciolo explores his extraordinary contribution to the development of the accounting profession. Paciolo is the first known writer to publish a work describing the double entry process.

“Lively history. . . . Show[s] double entry’s role in the creation of the accounting profession, and even of capitalism itself.”—The New Yorker Filled with colorful characters and history, Double Entry takes us from the ancient origins of accounting in Mesopotamia to the frontiers of modern finance. At the heart of the story is double-entry bookkeeping: the first system that allowed merchants to actually measure the worth of their businesses. Luca Pacioli—monk, mathematician, alchemist, and friend of Leonardo da Vinci—incorporated Arabic mathematics to formulate a system that could work across all trades and nations. As Jane Gleeson-White reveals, double-entry accounting was nothing short of revolutionary: it fueled the Renaissance, enabled capitalism to flourish, and created the global economy. John Maynard Keynes would use it to calculate GDP, the measure of a nation’s wealth. Yet double-entry accounting has had its failures. With the costs of sudden corporate collapses such as Enron and Lehman Brothers, and its disregard of environmental and human costs, the time may have come to re-create it for the future.

Luca Pacioli stood beside the great Leonardo da Vinci and gazed at The Last Supper. He saw immediately that something was terribly wrong. An orphan from a small town in Italy, Pacioli came of age during the Renaissance seemingly destined for a life of struggle and obscurity. But Pacioli had the good fortune of meeting mentors who recognized his uncanny ability with numbers and introduced him to renowned artists and philosophers, royalty, and popes. At a time when many still used Roman numerals and colleges didn’t even teach mathematics, Pacioli was determined to share his passion and make it accessible and understandable. Apprentice to an artist, but a terrible artist himself, he became a master at calculating mathematical perspective in paintings. Tasked with teaching mathematics with no textbook, he wrote his own—followed by books on double-entry bookkeeping, chess, and the divine proportion. In this way, Luca Pacioli, “the father of accounting,” still has something to teach us—not just about mathematics—but about how we account for setbacks in our lives and how we determine what our legacy will be.

Probably the most fundamental relationship in human history is that of the Market versus the Oikos (= the authoritarian ruled house, family, household or the State). Its main features and elements are analysed and newly defined as are its relations with town–country antagonisms or capitalism, nation, race, religion, and so on. Because it concerns a rather universal relationship, the definitions of the relevant elements are developed over time (from ancient Greeks to Nazi contexts) and place (in the West and the East, particularly China). Max Weber is chosen as our “sparring partner,” starting with his popular analysis of the relationship of capitalism and religion in the West and of Chinese society in the East

Even in the flattest landscape there are passes where the road first climbs to a peak and then descends into a new valley. Most of these passes are simply topography with little or no difference in climate, language, or culture between the valleys on either side. But some passes are different: they are true divides. History too knows such divides. Once these divides have been crossed, the social and political landscape changes; the social and political climate is different, and so is the social and political language. Some time between 1965 and 1973 we passed over such a divide and entered "the next century." Challenging, insightful, and provocative, Peter Drucker's The New Realities anticipates the central issues of a rapidly changing world. When it was initially published, in 1989, some reviewers mistakenly thought The New Realities was a book about the future, or in other words, a series of predictions. But, as indicated in the title, the book discusses realities. Drucker argues that events of the next thirty to forty years, or even further on, had already largely been defined by events of the previous half-century. Thus, Drucker discusses episodes in world history that had not yet happened at the time of the book's initial publication, such as: the archaism of the hope for "salvation by society" in "The End of FDR's America"; the democratization of the Soviet Union in "When the Russian Empire is Gone"; the technology boom of the 1990s in "The Information-Based Organization"; and the evolution of management in "Management as Social Function and Liberal Art." Graced with a new preface by the author that discusses both reactions to the original publication of the book and how important it is for decision-makers to consider the past and present when planning for the future, The New Realities is mandatory reading for understanding politics, government, the economy, information technology, and business in an ever-changing world.
