The second edition of this handbook offers a thoroughly updated overview of the different approaches and perspectives in communication ethics today. Extending the path paved by its predecessor, this handbook includes new issues and concerns that have emerged in the interim—from environmentalism to artificial intelligence, from disability studies to fake news. It also features a new structure, comprised of three sections representing a wide array of communication ethics: traditions, contexts, and debates. Rather than focusing exclusively on a subset of ethics (such as interpersonal communication, rhetoric, or journalism, as do other handbooks of ethics in communication), this collection provides a valuable resource for those who seek a broader basis on which to study communication ethics. This handbook is a must-read for faculty, graduate students, and advanced undergraduate students in all areas of communication studies, as well as in neighboring disciplines such as rhetoric, media studies, sociology, political science, cultural studies, and science and technology studies.
