Philosophers and theorists have wrestled with the question for decades. Costello shakes up the debate by carefully probing the aspirations of contemporary photography and vigorously challenging the assumptions of the most influential thinkers. - Dominic McIver Lopes, University of British Columbia, Canada An excellent critical introduction to the main debates in the philosophical study of photography from the early days until recent times. Unlike essays on cultural criticism, the book provides a thorough philosophical argumentation and, unlike other philosophical texts, it is deeply informed by the artistic practices. I very much recommend this book. - Paloma Atencia-Linares, Universidad Nacional Autonoma de Mexico This insightful and engaging book is a valuable resource for all who are interested in photography, whether as theorists, fans, users or practitioners.
