"obscurantism" seems a bit, er, on the contrary, derogatory...no?

That depends on what you're trying to obscure, Inselpeter.

Sometimes it's the only way to get satire published.

As you indicated in your original post, Inselpeter, it is not Yeat's label you are looking for. It's a commentator's label. That commentator may be no more credible in summing up Yeat's oeuvre than you or I.

"Intuetics" fits the bill, quite nicely, wouldn't you say?

If "poetics" is the study of "poetry", then "intuetics" is the study of "intuition". The conclusion is irresistible.

Two groshen, or an opera, whichever comes first. I think I'll settle for one groschen upfront, Inselpeter ... tho a "groschen" is "Inuit Poetry" to me.
