There are many ways to picture the world - Australian `x-ray' pictures, cubist collages, Amerindian split-style figures, and pictures in two-point perspective each draw attention to different features of what they represent. The premise of Understanding Pictures is that this diversity is the central fact with which a theory of figurative pictures must reckon.Lopes argues that identifying pictures' subjects is akin to recognizing objects whose appearances have changed over time. He develops a schema for categorizing the different ways pictures represent--the different kinds of meaning they have--and he contends that depiction's epistemic value lies in its representational diversity. He also offers a novel account of the phenomenology of pictorial experience, comparing pictures to visual prostheses like mirrors and binoculars.The book concludes with a discussion of works of art which have made pictorial meaning their theme, demonstrating the importance of the issues this book raises for understanding the aesthetics of pictures.
