Frankly, I think the short article is mostly marketing BS, an article to justify the differences in Max as a gca over others. I think he was trying to sound like he gets his ideas from a higher source, and to be just as confusing as he can be to make others think he knows more than they possibly ever can. Perhaps he is related to David Moriarity or Tom MacWood? (Just kidding, but similar thought processes to anyone who argues a lot)
I think its also a case of the more words used, the less validity to the theory. I would have preferred he said "I like rough edge bunkers to smooth capes and bays" to all that. (I would also prefer most participants here just say that, too)
That is all he can really tell us. However, the bunker he picks to illustrate the article is oddly smooth and simple on one side, and rugged on the other. If that is his idea of a naturally appearing bunker, its a miserable fail. It looks no more natural than any other bunker. And if not, then why not use a more artistic MacKenzie style bunker, even if artificial.
What is more "sincere" architecture - trying to look natural when its nearly impossible, or trying to be artistic when you know you can't be natural?
