Norwood Russell Hanson was a seminal figure in post-war philosophy and history of science. His major works are landmarks in conceptual analysis and the historical case-study approach in the philosophy of science.

Norwood Russell Hanson was one of the most important philosophers of science of the post-war period. Hanson brought Wittgensteinian ordinary language philosophy to bear on the concepts of science, and his treatments of observation, discovery, and the theory-ladenness of scientific facts remain central to the philosophy of science. Additionally, Hanson was one of philosophy’s great personalities, and his sense of humor and charm come through fully in the pages of Perception and Discovery. Perception and Discovery, originally published in 1969, is Hanson’s posthumous textbook in philosophy of science. The book focuses on the indispensable role philosophy plays in scientific thinking. Perception and Discovery features Hanson’s most complete and mature account of theory-laden observation, a discussion of conceptual and logical boundaries, and a detailed treatment of the epistemological features of scientific research and scientific reasoning. This book is of interest to scholars of philosophy of science, particularly those concerned with Hanson’s thought and the development of the discipline in the middle of the 20th century. However, even fifty years after Hanson’s early death, Perception and Discovery still has a great deal to offer all readers interested in science.

Originally published in 1963, The Concept of the Positron forms a detailed analysis of quantum theory. Whilst it is not as well known as Professor Hanson's previous book, Patterns of Discovery (1958), the text has many interesting aspects. In many ways it goes further than Hanson's earlier work in approaching the problems of theory competition and the rationality of science, topics that have since become central to the philosophy of science. It is also notable for a rigorous and forthright defence of the Copenhagen Interpretation. Taken together, the ideas presented in this book constitute a first-rate achievement in the history and philosophy of science. This paperback reissue comes with a new preface from Matthew Lund, Assistant Professor, Faculty of Philosophy and Religious Studies at Rowan University.

Filmmaker Errol Morris offers his perspective on the world and his powerful belief in the necessity of truth. In 1972, philosopher of science Thomas Kuhn threw an ashtray at Errol Morris. This book is the result. At the time, Morris was a graduate student. Now we know him as one of the most celebrated and restlessly probing filmmakers of our time, the creator of such classics of documentary investigation as The Thin Blue Line and The Fog of War. Kuhn, meanwhile, was—and, posthumously, remains—a star in his field, the author of The Structure of Scientific Revolutions, a landmark book that has sold well over a million copies and introduced the concept of “paradigm shifts” to the larger culture. And Morris thought the idea was bunk. The Ashtray tells why—and in doing so, it makes a powerful case for Morris’s way of viewing the world, and the centrality to that view of a fundamental conception of the necessity of truth. “For me,” Morris writes, “truth is about the relationship between language and the world: a correspondence idea of truth.” He has no patience for philosophical systems that aim for internal coherence and disdain the world itself. Morris is after bigger game: he wants to establish as clearly as possible what we know and can say about the world, reality, history, our actions and interactions. It’s the fundamental desire that animates his filmmaking, whether he’s probing Robert McNamara about Vietnam or the oddball owner of a pet cemetery. Truth may be slippery, but that doesn’t mean we have to grease its path of escape through philosophical evasions. Rather, Morris argues powerfully, it is our duty to do everything we can to establish and support it. In a time when truth feels ever more embattled, under siege from political lies and virtual lives alike, The Ashtray is a bracing reminder of its value, delivered by a figure who has, over decades, uniquely earned our trust through his commitment to truth. No Morris fan should miss it.

This New York Times bestselling Trump biography from a major American intellectual explains how a renegade businessman became one of the most successful -- and necessary -- presidents of all time. In The Case for Trump, award-winning historian and political commentator Victor Davis Hanson explains how a celebrity businessman with no political or military experience triumphed over sixteen well-qualified Republican rivals, a Democrat with a quarter-billion-dollar war chest, and a hostile media and Washington establishment to become president of the United States -- and an extremely successful president. Trump alone saw a political opportunity in defending the working people of America's interior whom the coastal elite of both parties had come to scorn, Hanson argues. And Trump alone had the instincts and energy to pursue this opening to victory, dismantle a corrupt old order, and bring long-overdue policy changes at home and abroad. We could not survive a series of presidencies as volatile as Trump's. But after decades of drift, America needs the outsider Trump to do what normal politicians would not and could not do.
