Philosophers have been thinking about lying for several thousand years, yet this topic has only recently become a central area of academic interest for philosophers of language, epistemologists, ethicists, and political philosophers. Lying: Language, Knowledge, Ethics, Politics provides the first dedicated collection of philosophical essays on the emerging topic of lying. Adopting an inter-subdisciplinary approach, this volume breaks new methodological ground in exploring the ways that a better understanding of language can inform the study of knowledge, ethics, or politics - and vice-versa. How can we lie when it is unclear what exactly we believe, or when we have contradictory beliefs? Can corporations lie, and if so how? Is lying always wrong, or always at least prima facie wrong? What can one learn from a liar? Can we lie to mindless machines? These engaging questions and many more are explored at length in this accessible reference text.
