Laurie: In a democracy, public art should bring people together either by expressing a consensus on a subject or by helping people to reconcile their differences and to recognize that no single opinion is definitive.
Laurie's 1st Claim
In a democracy, public art should bring people together either by showing a consensus view by helping people to reconcile their different but valid views. Does Elsa argue that public art shouldn't be doing either of those things?
Yes, kind of. She is saying that public art should emphasize it when people hold radically different opinions. Laurie made it sound more like art should help people reconcile their differences.
How are those different? Laurie's sentiment is more like, A reconciliation involves bringing things together in harmony. When we reconcile paradoxes on Paradox questions, we make it so that the background and the surprising claim can live harmoniously in our heads.
Elsa's sentiment is more like,
Laurie's 2nd Claim
Contemporary public art creates only acrimony Does Elsa argue that public art has created stuff other than (or in addition to) acrimony?
No, she never comments on what modern public art has or hasn't done. Her comments are only in the space of what it should or could do.
Laurie's 3rd Claim
Public art has failed in its task. Does Elsa argue that public art hasn't failed in its task?
No Elsa's comments aren't about contemporary public art at all. They're about all public art. And it's about what public art should or could do, not about what it has or hasn't done.
Goal
It seems like the only disconnect we found related to this idea of what public art should be doing:
When people have different opinions on a subject, should public art be emphasizing those differences, or should it be bringing people together by reconciling those differences?
