The book “Leviathan in the Teachings on the State of Thomas Hobbes” by Carl Schmitt is a deep and multilayered study that immerses the reader in the philosophical and political ideas of one of the most influential thinkers of the XVII century. Schmitt, known for his work on political theory and law, offers a unique perspective on the concept of the state, viewing it through the prism of the Hobbesian "Leviathan", which has become a symbol of absolute power and centralized management. In his book, Schmitt analyzes Hobbes's main ideas, focusing on his view of the state as an artificial creation necessary to maintain order and prevent chaos. Hobbes argues that in the state of nature man is in constant war of all against all, and only a strong power can ensure peace and security. Schmitt, in turn, not only retells Hobbes' ideas, but also develops them, questioning some aspects of his theory and exploring how they relate to contemporary political realities. This book will be of interest to a wide range of readers: from students and teachers studying political philosophy to professionals in the field of law and politics. Fans of history and state theory will also find in it a lot of valuable ideas and arguments. Schmitt, as a master of provocative and profound reflections, addresses those who seek to understand how ideas of the past affect modernity, and how they can be applied to analyze current political crises. The topics raised in Leviathan in the Doctrine of the State cover not only philosophical aspects, but also practical issues relating to power, legitimacy, and the legal order. Schmitt explores how Hobbes' concept of sovereignty can be applied in the modern world, where state boundaries and traditional forms of power are being severely tested. It raises questions about how a state can maintain its legitimacy in the face of globalization, migration, and crises that require new approaches to governance. Carl Schmitt's style is bright and convincing. His arguments are permeated with deep historical and philosophical references, which makes reading not only informative, but also fascinating. Schmitt is also known for his other works, such as "The Concept of Political" and "Theology of Politics", which also explore issues of power and legitimacy, but from different perspectives. In Leviathan, he continues this tradition by offering the reader an opportunity to gain a deeper understanding of how Hobbes' ideas might be relevant in the modern world. The book “Leviathan in the Teachings about the State of Thomas Hobbes” is not just an academic study, but also an important contribution to modern political philosophy. Schmitt makes us think about how we understand power and the state, and what lessons we can learn from the past to solve modern problems. This work will be a valuable addition to the library of anyone interested in political theory, philosophy and history, and will open new horizons for reflection on the future of our society.
