The writer is writing on "what is art", while being a gallery represented professional artist (i.e. sold his art in the system) and a paid professor(again, professional system player).

It's brand awareness building, also known as self-promotion. "See, I'm in the racquet, but I'm not like the others!" He went on to publish a book on the subject, 3 years later. [ source : gallery statement, wikipedia ]

He is pushing art as politics and himself as the arbiter, all while preaching in the royal "We". Like I wrote, how tedious.
