Testimony: A Philosophical Introduction provides an epistemology of testimony that surveys this rapidly growing research area while incorporating a discussion of relevant empirical work from social and developmental psychology, as well as from the interdisciplinary study of knowledge-creation in groups. The past decade has seen a number of scholarly monographs on the epistemology of testimony, but there is a dearth of books that survey the current field. This book fills that gap, assessing the strengths and weaknesses of all major competing theories. All chapters conclude with Suggestions for Further Reading and Discussion Questions.
