Do I love you because you're beautiful? Or are you beautiful because I love you? - Oscar Hammerstein
This one was just fun so I thought I'd include it. It's pretty self explanatory but is the person and the object we vie for the "apple of our eye" because we deem it so or are they dear to us because others see them that way.
Much like Debords Chiasmus, do we consider them precious because there's a collective desire for our love or do is there a desire for our love because we consider them precious.
