"There is nothing I can say about myself as a whole simply and completely, without intermingling and admixture. The most universal article of my own Logic is Distinguo. I always mean to speak well of what is good..."
-Michel de Montaigne, "Of the inconstancy of our actions", tr. M.A. Screech
Today is (or rather, was) the Feast of St. Barbara. She did not exist, but if she had existed she would certainly have been confined to a tower with two windows, and insisted that a third needed to be added; and she would have not only specified this declaratively ("Look, I insist that nWindows == 3") but directed the workers in carrying it out. Thus, she is the patron saint of engineers, and by extension mathematicians; and by even more extension of gunners and other People Who Knock Holes In Things, and by even more extension of those in danger of sudden death, though picking a specific martyr for that seems a little exclusionary -- there was a lot of danger of sudden death for Nonconformists in those days. Anyway, since I am sort of a mathematician and sort of an engineer, this is a mildly celebratory day for me; and I feel entitled to indulge in wanton contrafactuals like the one that began this paragraph, since I am also something of a logician. It is, as following the first link will confirm, not an official feast anymore, but then I am not exactly an official anything myself these days; my excuses for parties are ecumenical, though leaning towards more familiar (to me) traditions.
I also wished to argue for extending Barbara's patronage to many-valued logic: if there was ever a clear message that two values are not enough to capture all truths, hers was it.
But out of the third lattice Under low eaves like wings Is a new corner of the sky And the other side of things. --G.K. Chesterton, "The Ballad of Saint Barbara"
