ABSTRACT
This introduction presents an overview of key concepts covered in the subsequent chapters of this book. The book aims to provoke engagement and thinking on ethics and security by bringing together both authors who have been sceptical of the ethical potential in security and emerging and established authors working on developing alternative visions of what positive ethical notions of security might look like. It then bridges approaches that work self-consciously in the genres of applied or continental ethics, and more broadly normative perspectives. The book also presents different visions of ethical security, from different angles and theoretical perspectives, often in ways that contradict each other. Foundational architectures of security theory and practice what we have called security ontologies have had a great influence, an enabling and constraining effect, on the ethical possibilities of security practice.
