From Don Jewett
Feedback is apologetic over not having been able to name a category that Mike Trier suggested – “The category of [named] categories of interesting names” (16 April).
In the interests of full disclosure and the safety warnings that so intrigue you, you should have alerted your readers not to try to name “The category of un-named categories of interesting names”.
Bertrand Russell became almost suicidal about whether such a category would contain itself. Let not this problem spread beyond UK shores, by modern means of meta-categorisation.
