A reader follows up on Cohen’s Law.

Derb — Concerning: “Whoever resorts to the argument that ‘whoever resorts to the argument that … has automatically lost the debate’ has automatically lost the debate.”
In technical documents (and, I suspect, legal ones), there’s often a need to have a blank page inserted. These are usually identified by the sentence:
“This page intentionally left blank, except for the sentence ‘This page intentionally left blank, except for … …blank.”
Sometimes the text fills the entire page.

[Me] Seems to me it could fill a great deal more than that. In fact, as I recall, it is written out in full in the book of house rules for Hilbert’s Hotel.
