Untitled

The following was presented by Boolos in the Harvard Review of Philosophy, 1996.

Three Gods, A B and C, are called, in some order, True
False and Random. True always speaks truly, False
always speaks falsely, but whether Random speaks truly
or falsely is a completely random matter. Your task is
to determine the identities of A, B and C by asking
three yes-no questions; each question must be put to
exactly one God. The Gods understand English, but will
answer all questions in their own language, in which
the words for 'yes' and 'no' are 'da' and 'ja', in some

And yes, I did solve it myself. That strikes me as the best evidence that it's no that difficult: I'm just not that smart.) Captain Wacky 07:13, 5 March 2006 (UTC)[reply]

Frege's Basic Law V

In the article, the 3rd paragraph of the section Work mentions Boolos' work on Frege's Grundgesetze and the influence of Russell's paradox on it. At the end, the sentence "The resulting system [Frege Arithmetic, i.e., Frege's logic of Grundgesetze with Basic Law V replaced with Hume's Principle] has since been the subject of intense work" has the tag {{Citation needed}}. Would a reference to, for instance, Richard Heck's book Frege's Theorem (Book info // list of Heck's publications) — which discusses Frege Arithmetic almost exclusively — be considered as a suitable citation?
