Splitting and Doubling

1.) My first questions revolves around the basic concept of the integration of bodily experiences and sculpture. Wagner states that sculptures are different from architectural functions based upon the fact that architectural functions hold some substantive purpose for humans (i.e. bathrooms), and sculptures do not. She then goes on to state "the body still haunts Matta-Clark's sculpture..not only does it hover there as repression or memory, but it is also summoned by the range of behaviours and optics..." (pg.561) How are these bodily associations able to depict a sculpture? What specific bodily functions? Are the basic or something more complex/metaphorical?

2.) Wagner states that "sculpture is a kind of relay or interchange between vision and association" (pg.565). This quote is stating that a sculpture meaning is based upon the interpretation and experience of the audience. The experience that the audience had encountered in relation to that sculpture or the place it is located is vital, for that is the factor that will allow the audience to realize the purpose of the sculpture. My question is that, no audience member will have the same memory or experience of a particular space or object, thus how does the artist control the interpretation of the sculpture? Also, could the lack of control of the direction of interpretation distort the artists vision for the piece?
