The document discusses abstract art and provides examples of abstract works. It notes that abstract artists did not try to depict objects realistically, but rather used color and shape to convey emotions. Abstract or non-objective art does not depict specific objects, but rather uses forms and colors without representing anything in the real world. Examples of abstract artworks by Sol LeWitt are provided, including wall drawings and incomplete open cubes, which reduce forms to basic geometric shapes presented in an impersonal way.
