Graham McAleer's Erich Przywara and Postmodern Natural Law is the first work to present in an accessible way the thinking of Erich Przywara (1889-1972) for an English-speaking audience. Przywara's work remains little known to a broad Catholic audience, but it had a major impact on many of the most celebrated theologians of the twentieth century, including Hans Urs von Balthasar, Karl Rahner, Edith Stein, and Karl Barth. Przywara's ground-breaking text Analogia Entis (The analogy of being) brought theological metaphysics into the modern era. While the concept of analogy of being is typically understood in static terms, McAleer explores how Przywara transformed it into something dynamic. McAleer shows the extension of Przywara's thought into a range of disciplines: from a new theory of natural law to an explanation of how misunderstanding the analogy of being lies at the foundation of the puzzles of modernity and postmodernity. He demonstrates, through Przywara's conceptual framework, how contemporary moral problems, such as those surrounding robots, Islam and sumptuary laws, Nazism (including fascism and race), embryos, migration, and body modification, among others, are shaped by the failure of Western thought to address metaphysical quandaries. McAleer updates Przywara for a new audience searching for solutions to the failing humanism of the current age. This book will be of interest to intellectuals and scholars in a wide range of disciplines within philosophy or theology, and will appeal especially to those interested in systematic and moral theology.
