In the course of articulating his monumental theory of political justification, Thomas Hobbes developed a sustained and detailed approach to law and legal questions. Unfortunately legal philosophers have largely ignored Hobbes' remarks on law, and philosophers have only begun to explore it. This collection aims to spur interest in Hobbes' legal philosophy, by collecting the best recent philosophical writings on Hobbes' views on law. The essays address questions such as whether Hobbes was a positivist, a natural law theorist or neither. They also address Hobbes' treatment of natural law, his account of equity, as well as his more specific views on topics like contract, punishment, self-defense, civil disobedience, and international law. The essays collected here provide an excellent survey of the various legal questions Hobbes addressed.

Conflict over cultural heritage has increasingly become a standard part of war. Today, systematic exploitation, manipulation, attacks, and destruction of cultural heritage by state and non-state actors form part of most violent conflicts across the world. Such acts are often intentional and based on well-planned strategies for inflicting harm on groups of people and communities. With this increasing awareness of the role cultural heritage plays in war, scholars and practitioners have progressed from seeing conflict-related destruction of cultural heritage as a cultural tragedy to understanding it as a vital national security issue. There is also a shift from the desire to protect cultural property for its own sake to viewing its protection as connected to broader agendas of peace and security. Concerns about cultural heritage have thus migrated beyond the cultural sphere to worries about the protection of civilians, the financing of terrorism, societal resilience, post-conflict reconciliation, hybrid warfare, and the geopolitics of territorial conflicts. This volume seeks to deepen public understanding of the evolving nexus between cultural heritage and security in the twenty-first century. Drawing on a variety of disciplines and perspectives, the chapters in this volume examine a complex set of relationships between the deliberate destruction and misuse of cultural heritage in times of conflict, on the one hand, and basic societal values, legal principles, and national security, on the other.

The threat posed by the recent rise of transnational non-state armed groups does not fit easily within either of the two basic paradigms for state responses to violence. The civilian paradigm focuses on the interception of demonstrable immediate threats to the safety of others. The military paradigm focuses on threats posed by collective actors who pose a danger to the state's ability to maintain basic social order and, at times, the very existence of the state. While the United States has responded to the threat posed by non-state armed groups by using tools from both paradigms, it has placed substantially more emphasis on the military paradigm than have other states. While several reasons may contribute to this approach, one may be the assumption that a state must use each set of tools strictly according in accordance with the principles that underlie each paradigm. Implicit in this assumption may be the sense that the only alternative to the civilian paradigm is the unqualified military one. The chapters in this book suggest, however that we need not see the options as confined to this binary choice. It may be profitable to consider borrowing elements from each paradigm on some occasions to act more expansively than the conventional civilian paradigm allows, but less expansively than the conventional military paradigm would permit. At the same time, the mixing of the categories comes with its own ethical and legal risks that should be scrutinized.

The chief means to limit and calculate the costs of war are the philosophical and legal concepts of proportionality and necessity. Both categories are meant to restrain the most horrific potential of war. The volume explores the moral and legal issues in the modern law of war in three major categories. In so doing, the contributions will look for new and innovative approaches to understanding the process of weighing lives implicit in all theories of jus in bello: who counts in war, understanding proportionality, and weighing lives in asymmetric conflicts. These questions arise on multiple levels and require interdisciplinary consideration of both philosophical and legal themes.

Cyber weapons and cyber warfare have become one of the most dangerous innovations of recent years, and a significant threat to national security. Cyber weapons can imperil economic, political, and military systems by a single act, or by multifaceted orders of effect, with wide-ranging potential consequences. Unlike past forms of warfare circumscribed by centuries of just war tradition and Law of Armed Conflict prohibitions, cyber warfare occupies a particularly ambiguous status in the conventions of the laws of war. Furthermore, cyber attacks put immense pressure on conventional notions of sovereignty, and the moral and legal doctrines that were developed to regulate them. This book, written by an unrivalled set of experts, assists in proactively addressing the ethical and legal issues that surround cyber warfare by considering, first, whether the Laws of Armed Conflict apply to cyberspace just as they do to traditional warfare, and second, the ethical position of cyber warfare against the background of our generally recognized moral traditions in armed conflict. The book explores these moral and legal issues in three categories. First, it addresses foundational questions regarding cyber attacks. What are they and what does it mean to talk about a cyber war? The book presents alternative views concerning whether the laws of war should apply, or whether transnational criminal law or some other peacetime framework is more appropriate, or if there is a tipping point that enables the laws of war to be used. Secondly, it examines the key principles of jus in bello to determine how they might be applied to cyber-conflicts, in particular those of proportionality and necessity. It also investigates the distinction between civilian and combatant in this context, and studies the level of causation necessary to elicit a response, looking at the notion of a 'proximate cause'. Finally, it analyses the specific operational realities implicated by particular regulatory regimes. This book is unmissable reading for anyone interested in the impact of cyber warfare on international law and the laws of war.
