"The quality of a work depends on the trajectory it describes in the cultural landscape". (Bourriard, Post Production, p 40)

By making this statement Bourriard is asserting that the aesthetic element is not in any way part of defining the quality of a work of art. The statement was made directly following this sentence re the idea that a chair is not a sculpture because you can't see it when you are sitting in it. Sot it's functional value prevents it from being and art object, "but I don't think that makes any sense" says Bourriard.

In other words, the function of an object does not detract from its value as art.
