This engaging Handbook critically examines the moral opportunities and challenges surrounding artificial intelligence. It provides a comprehensive overview of the most pressing problems concerning this technology by drawing on a wide range of analytical methods, traditions and approaches. Advocating for a diversification of the study of ethics and AI, this Handbook covers the foundations of the field before delving into the challenges of responsibility, justice and authority in an AI-centred landscape. Chapter authors champion typically underrepresented or marginal traditions, including continental philosophy, indigenous cosmologies, queer studies, post-colonial theories, African philosophies, disability studies, and feminist ethics. Balancing legal and moral philosophies, the Handbook surveys the transformative present of AI, while also reckoning with the ethics of an increasingly inscrutable future. The Handbook on the Ethics of Artificial Intelligence is a crucial reference point for students and scholars of AI ethics, philosophy, technology and sociology. It will also appeal to legal practitioners, policy analysts, and regulators looking for a fundamental resource in AI ethics.
