This groundbreaking book presents a new understanding of ideological change. It shows how and why America's political parties have evolved.

Conventional wisdom today says that to survive, companies must move beyond incremental, sustaining innovation and invest in some form of radical innovation. "Disrupt yourself or be disrupted!" is the relentless message company leaders hear. The Power of Little Ideas argues there's a "third way" that is neither sustaining nor disruptive. This low-risk, high-reward strategy is an approach to innovation that all company leaders should understand so that they recognize it when their competitors practice it, and apply it when it will give them a competitive advantage. This distinctive approach has three key elements: It consists of creating a family of complementary innovations around a product or service, all of which work together to make that product more appealing and competitive. The complementary innovations work together as a system to carry out a single strategy or purpose. Crucially, unlike disruptive or radical innovation, innovating around a key product does not change the central product in any fundamental way. In this powerful, practical book, Wharton professor David Robertson illustrates how many well-known companies, including CarMax, GoPro, LEGO, Gatorade, Disney, USAA, Novo Nordisk, and many others, used this approach to stave off competitive threats and achieve great success. He outlines the organizational practices that unintentionally torpedo this approach to innovation in many companies and shows how organizations can overcome those challenges. Aimed at leaders seeking strategies for sustained innovation, and at the quickly growing numbers of managers involved with creating new products, The Power of Little Ideas provides a logical, organic, and enduring third way to innovate.

Ideas are everywhere, but those with the greatest problem-solving, business-transforming, and life-changing potential are often hard to identify. Even when we recognize good ideas, applying them to everyday obstacles—whether in the workplace, our homes, or our civic institutions—can seem insurmountable. According to Matthew Syed, it doesn't have to be this way. In Rebel Ideas, Syed argues that our brainpower as individuals isn't enough. To tackle problems from climate change to economic decline, we'll need to employ the power of "cognitive diversity." Drawing on psychology, genetics, and beyond, Syed uses real-world scenarios including the failings of the CIA before 9/11 and a communication disaster at the peak of Mount Everest to introduce us to the true power of thinking differently. Rebel Ideas will strengthen any kind of team, while including advice on how, as individuals, we can embrace the potential of an "outsider mind-set" as our greatest asset. Matthew Syed is the Sunday Times bestselling author of Black Box Thinking, Bounce, and The Greatest. He writes an award-winning newspaper column in The Times and is the host of the hugely successful BBC podcast Flintoff, Savage and the Ping Pong Guy.

This Element develops an analytical framework for understanding the role of ideas in political life and communication. Power in Ideas argues that the empirical study of ideas should combine interpretive approaches to derive meaning and understand influence with quantitative analysis to help determine the reach, spread, and impact of ideas. This Element illustrates this approach through three case studies: the idea of reparations in Ta-Nehisi Coates's “The Case for Reparations,” the idea of free expression in Mark Zuckerberg's Facebook policy speech at Georgetown University, and the idea of universal basic income in Andrew Yang's “Freedom Dividend.” Power in Ideas traces the landscapes and spheres within which these ideas emerged and were articulated, the ways they were encoded in discourse, the fields they traveled across, and how they became powerful.

Through a focused and systematic examination of late medieval scholastic writers - theologians, philosophers and jurists - Joseph Canning explores how ideas about power and legitimate authority were developed over the 'long fourteenth century'. The author provides a new model for understanding late medieval political thought, taking full account of the intensive engagement with political reality characteristic of writers in this period. He argues that they used Aristotelian and Augustinian ideas to develop radically new approaches to power and authority, especially in response to political and religious crises. The book examines the disputes between King Philip IV of France and Pope Boniface VIII and draws upon the writings of Dante Alighieri, Marsilius of Padua, William of Ockham, Bartolus, Baldus and John Wyclif to demonstrate the variety of forms of discourse used in the period. It focuses on the most fundamental problem in the history of political thought - where does legitimate authority lie?
