analyzing a painting

Art is something that all cultures around the world share. and it seems as thought that humans are hot wired to express themselves through it or by other means such as music. art and music are things that are developed over time. coming into existence because people found time in their lives to alleviate their boredom by painting on cave walls or dancing around a fire. but with out the knowledge of previous art revolutions art can not progress nor be translated in a meaningful manner.
art says allot about a group of people, much like the food they eat. it seems that art reflects exactly what is going on at the time. PKD introduces a very interesting character. Luba Luft is one of the androids that Rick Deckard is seeking out to retire for a 1,000 dollar bounty. but this character unlike other androids, is "beneficial" to human society. Luba luft is one of the few who is able to act and sing like a human being. expressing herself through her beautiful voice and well rehearsed lines, she caries on the the very organic and natural occurrence in human history.
art and music are passed on through generations. it is something that is taught and experienced. but Luba luft, who is completely man made and is of the age of a small infant possesses the capability that people spent thousands of years developing, only happening because of events and experiences that inspired people to preform the art opera. Luba luft apparently has been programed to be a great singer, placed within her memory experiences that led her to be an actress and opera singer. a great singer and performer, but no better than a humanoid mp3 player.
in this famous painting a man finds himself alone screaming. most people have seen this painting and have learned about it in school. i know that it is an expressionistic painting, meaning that the artist relied on his emotion to guide his brush. Munch's painting is very important not only because of its popularity but also because of its similarities in meaning with the ideas that PKD presents in this book. 100 years ago it seems that people wanted to fit in, and if one didn't they were out casted, sometimes forced to create wonderful works of art like this one, or like Van Gough's paintings. androids too seem to want to be human. and to them feel and act as though they are human. my prediction is that maybe these extremely intelligent beings will learn to develop empathy, and maybe before that start to develop a culture of their own.
