What does art look like when it becomes philosophy? -- I like the question better than the answer. Yes, it's Andy Warhol's world, but I don't think he was interested in philosophy. His uniqueness comes from his willingness to play at art in reverse; to attach the inauthenticity of the commercial image to the energizing capacity of the artist.
If advertising isolates us as consumers, Warhol's blankness arrests desire and inspires participation.
