On purpose

[-JKP-]

...
I was not suggesting for a moment that the author was "doing calligraphy for fun", which should be obvious from what I have written. The pleasure that the author was getting from it was not the pleasure of practising calligraphy just as when Newton wrote his Principia he didn't do it, because he wanted to practice his calligraphy....

Then what was the fun? You have suggested on numerous threads that there might be a high proportion of "nullwords". Which means the actual content would be quite low and the writing itself would be mostly work rather than fun. It's more than 200 pages.
