Practices of Looking 145-151

By quoting the words of great philosopher Plato, the authors help to expand the definition of the word realism so that the reader can get an understanding from a historical perspective like his (150). He says that the way an image has depth is like deception and not realism (150). Like for example art pieces that are done in high relief show the depth of an object but still do not depict realism according to Plato. Depth helps to bring a different perspective to the viewer which can sometimes aid in the realism of what we see.
