The "large and startling" phrase is from Flannery O'Connor—
From Georgia College, Milledgeville, GA— … in Flannery O'Connor's essay "The Fiction Writer and His Country"… she explains why she writes the way she does: "When you can assume that your audience holds the same beliefs you do, you can relax a little and use more normal means of talking to it; when you have to assume that it does not, then you have to make your vision apparent by shock— to the hard of hearing you shout, and for the almost-blind you draw large and startling figures" (Mystery and Manners , p. 34). |

Pope Benedict XVI at the 2012 Easter Vigil on April 7 —
"The great hymn of the Exsultet, which the deacon sings at the beginning of the Easter liturgy, points us quite gently towards a further aspect. It reminds us that this object, the candle, has its origin in the work of bees. So the whole of creation plays its part. In the candle, creation becomes a bearer of light.
But in the mind of the Fathers, the candle also in some sense contains a silent reference to the Church. The cooperation of the living community of believers in the Church in some way resembles the activity of bees. It builds up the community of light."

From Joyce's 1912 Trieste lecture on Blake:
"Michelangelo's influence is felt in all of Blake's work, and especially in some passages of prose collected in the fragments, in which he always insists on the importance of the pure, clean line that evokes and creates the figure on the background of the uncreated void."

An inaccuracy in a passage linked to yesterday—
“The created universe, the whole of things, is,
in words from Joyce’s Ulysses , ‘predicated on the void.'”
The “predicated” phrase seems to be absent from Ulysses .
Joyce does, however, have the following (from ricorso.net)—
“William Blake” (March 1912) – cont.: ‘Armed with this two-edged sword, the art of Michaelangelo and the revelations of Swedenborg, Blake killed the dragon of experience and natural wisdom, and, by minimising space and time and denying the existence of memory and the senses, he tried to paint his works on the void of the divine bosom. [See note, infra.]To him, each moment shorter than a pulse-beat was equivalent in its duration to six thousand years, because in such an infinitely short instant the work of the poet is conceived and born. To him, all space larger than a red globule of human blood was visionary, created by the hammer of Los, while in a space smaller than a globule of blood we approach eternity, of which our vegetable world is but a shadow. Not with the eye, then, but beyond the eye, the soul and the supreme move must look, because the eye, which was born in the night while the soul was sleeping in rays of light, will also die in the night. […] The mental process by which Blake arrives at the threshold of the infinite is a similar process. Flying from the infinitely small to the infinitely large, from a drop of blood to the universe of stars, his soul is consumed by the rapidity of flight, and finds itself renewed and winged and immortal on the edge of th dark ocean of God. And althought he based his art on such idealist premises, convinced that eternity was in love with the products of time, this sons of God with the sons of [MS ends here].’ (Critical Writings, 1959, 1966 Edn., pp.221-22; quoted [in part] in Richard Ellmann, James Joyce, 1965 Edn., p.330.) [For full text, see RICORSO Library, “Major Authors”, via index, or direct.] Note – for “void” [supra] , cf. Stephen in “Scylla & Charybdis”: ‘Fatherhood […] is a mystical estate, an apostolic succession, from only begetter to only begotten. On that mystery and not on the madonna which the cunning Italian intellect flung to the mob of Europe the church is founded and founded irremovably because founded, like the world, macro- and microcosm, upon the void.’ (Ulysses, Penguin Edn. 1967, p.207; [my itals.].) |
Some academics may prefer a more leftist version of
“predicated on the void”—
For St. Dismas, a Holy Saturday story—
"Mr. Rosensaft told another story to illustrate his friend's mix of grit and wit. Mr. Steinberg was negotiating one day with the French culture minister to recover paintings stolen from Jews during the Holocaust. The minister huffed that Mr. Steinberg knew nothing about art.
'You're right,' Mr. Steinberg said. 'I don't know anything about art. I'm from Brooklyn. I know about stolen goods.'"

William Hamilton, the retired theologian who declared in the 1960s that God was dead, died Tuesday [Feb. 28, 2012] in his downtown Portland apartment at 87. Hamilton said he'd been haunted by questions about God since he was a teenager. Years later, when his conclusion was published in the April 8, 1966, edition of Time Magazine, he found himself in a hornet's nest. Time christened the new movement "radical theology" and Hamilton, one of its key figures, received death threats and inspired angry letters to the editor in newspapers that carried the story. He encountered hostility at Colgate Rochester Crozer Divinity School, where he had been teaching theology, and lost his endowed chair in 1967. Hamilton moved on to teach religion at New College in Sarasota, Fla. |

"To some, Inception is a film about the creative process, specifically filmmaking, with Cobb as the director, Saito the producer, Ariadne the screenwriter, Eames the actor, and so on. To others the entire movie is a dream in that the film supports Carl Jungs' dream analysis; with all of the supporting characters acting as classical archetypes to Cobb's multiple personalities (which would also justify the lack of development in the supporting characters). The fact that Inception , in the few months since its initial release, has already given rise to so much discussion and critical thought is much more revelatory than whether or not Cobb is still dreaming."

March 28 review in the Times Literary Supplement of
George Steiner's new book The Poetry of Thought—
"If this new book opens with the concession that
language has neither the performative power of music
nor the elegant precision of mathematics,
it is language, for Steiner, that defines the human.
The survey accordingly begins from the ancient Greek
view of man as the 'language-animal.'"
A check of this phrase yields, in a 1969 Steiner essay,
"The Language Animal," a Greek form of the phrase—
In short, the least inadequate definition we can arrive at
of the genus homo , the definition that fully distinguishes
him from all neighbouring life-forms, is this:
man is a zoon phonanta , a language-animal.
— p. 10 in Encounter , August 1969 (essay on pp. 7-23)
After introducing "language-animal" as a translation of "zoon phonanta " in 1969,
Steiner in later writing went on to attribute this phrase to the ancient Greeks.
"The inception of critical thought, of a philosophic anthropology,
is contained in the archaic Greek definition of man as a
'language-animal'…."
— George Steiner, Real Presences , U. of Chicago Press, 1991, p. 89
"… the 'language-animal' we have been since ancient Greece
so designated us…. "
— George Steiner, Grammars of Creation , Yale U. Press, 2002, p. 265
Despite this, there seems to be no evidence for use of this phrase
by the ancient Greeks.

There are also no results from searches for the similar phrases
"ζωον φωναντα," "ζωον φωνᾶντα," and "ζῷον φωναντα."

Doodle Dandy and The Purloined Diamond (scroll down).
From “Schrödinger’s Cat,” by Ursula K. Le Guin (Buffalo Gals and Other Animal Presences ) …. There was silence then: deep silence. We both gazed, I afoot, Rover kneeling, at the box. No sound. Nothing happened. Nothing would happen. Nothing would ever happen, until we lifted the lid of the box. “Like Pandora,” I said in a weak whisper. I could not quite recall Pandora’s legend. She had let all the plagues and evils out of the box, of course, but there had been something else, too. After all the devils were let loose, something quite different, quite unexpected, had been left. What had it been? Hope? A dead cat? I could not remember. Impatience welled up in me. I turned on Rover, glaring. He returned the look with expressive brown eyes. You can’t tell me dogs haven’t got souls. “Just exactly what are you trying to prove?” I demanded. “That the cat will be dead, or not dead,” he murmured submissively. “Certainty. All I want is certainty. To know for sure that God does play dice with the world.” I looked at him for a while with fascinated incredulity. “Whether he does, or doesn’t,” I said, “do you think he’s going to leave you a note in the box?” I went to the box, and with a rather dramatic gesture, flung the lid back. Rover staggered up from his knees, gasping, to look. The cat was, of course, not there. Rover neither barked, nor fainted, nor cursed, nor wept. He really took it very well. “Where is the cat?” he asked at last. “Where is the box?” “Here.” “Where’s here?” “Here is now.” “We used to think so,” I said, “but really we should use larger boxes.” He gazed about in mute bewilderment, and did not flinch even when the roof of the house was lifted off just like the lid of the box, letting in the unconscionable, inordinate light of the stars. He had just time to breathe, “Oh, wow!” I have identified the note that keeps sounding. I checked it on the mandolin before the glue melted. It is the note A, the one that drove the composer Schumann mad. It is a beautiful, clear tone, much clearer now that the stars are visible. I shall miss the cat. I wonder if he found what it was we lost? |

The diamond shape of yesterday's noon post
is not wholly without mathematical interest …
"Every triangle is an n -replica" is true
if and only if n is a square.
The 16 subdiamonds of the above figure clearly
may be mapped by an affine transformation
to 16 subsquares of a square array.
(See the diamond lattice in Weyl's Symmetry .)
Similarly for any square n , not just 16.
There is a group of 322,560 natural transformations
that permute the centers of the 16 subsquares
in a 16-part square array. The same group may be
viewed as permuting the centers of the 16 subtriangles
in a 16-part triangular array.
(Updated March 29, 2012, to correct wording and add Weyl link.)
The diamond from the Chi-rho page

Remarks on Citizen Kane from The New York Times—
"… a kind of metaphysical detective story…. At the end we realize that the fragments are not governed by any secret unity: the detested Charles Foster Kane is a simulacrum, a chaos of appearances.” Borges concluded by quoting Chesterton, "there is nothing more frightening than a labyrinth that has no center." *
* The actual quote is from a Father Brown mystery, "The Head of Caesar," "'What we all dread most,' said the priest in a low voice, 'is a maze with no centre….'"

"Abramson did not always get his way; he didn't have to win, but never took his eye off the ball— the Museum had to emerge the better. He did not take loses personally but pragmatically. A design for the Museum building done by an architect from his firm was charitably speaking 'mediocre.' It was replaced by a brilliant building designed by James Ingo Freed who rightfully regarded it as the master work of his distinguished career. Abramson became Freed's champion. He pushed the design team for a happy ending, saying that he knew the American people and they needed an uplifting ending since the subject of the Holocaust was so very depressing."

"The first half of the film has the predominant

half, the film becomes darker as it delves deeper

the line between the sane and the insane."

On Harvard's Memorial Church in 2007—
"John Harvard left no male heir to carry on the Harvard family name. Instead, the naming of the College in his honor was the undying legacy that his friends decided to grant to him. In so doing, they were saying to every succeeding generation that this was the kind of man whom they wanted others to emulate, whose spirit of courage, self-sacrifice and generosity embodied the very best of what they hoped Harvard College should become. On November 4, 2007, the gift of a tablet was presented to Harvard Memorial Church by the dean of Southwark Cathedral, London, the Rev. Colin Slee, and Emmanuel College, to commemorate the 400th anniversary of John Harvard's baptism. This, along with a combined brief exhibit called 'Heralds of Light,' which consisted in part of showing John Harvard's baptismal page from the Southwark records and his Emmanuel College signature— brought over for the occasion from England by Southwark and Emmanuel representatives—was about all the attention that Harvard University could muster to remember the 400th birthday of its namesake." — Arseny James Melnick (A.M., Harvard University, 1977), |

REVISITING ‘THE LADY FROM DUBUQUE’
Origin of the title: Harold Ross, founding editor of The New Yorker, was once asked to describe the average reader of the magazine. He said, “One thing I know, the magazine is not going to be written for the little old lady from Dubuque.” Naming his character after Ross’s imaginary small-town creature was typically whimsical of Albee. The play’s title character is extremely worldly and other-worldly at the same time. “If The New Yorker is written for anyone, it’s written for her,” Albee said. |

A search tonight for material related to the four-color
decomposition theorem yielded the Wikipedia article
Functional decomposition.
The article, of more philosophical than mathematical
interest, is largely due to one David Fass at Rutgers.
(See the article's revision history for mid-August 2007.)
Fass's interest in function decomposition may or may not
be related to the above-mentioned theorem, which
originated in the investigation of functions into the
four-element Galois field from a 4×4 square domain.

Yesterday afternoon's post Universals Revisited linked
(indirectly) to an article in the current New Yorker on
the Book of Revelation —
"The Big Reveal: Why Does the Bible End That Way?"
The connection in that post between universals and Revelation
may have eluded readers unfamiliar with a novel by
Charles Williams, The Place of the Lion (London, Gollancz, 1931).
The article's author, Adam Gopnik, appears in the following
Google Book Search, which may or may not help such readers.
Should Gopnik desire further information on Williams and salvation,
he may consult Steps Toward Salvation: An Examination of Coinherence
and Substitution in the Seven Novels of Charles Williams ,

Below is a screenshot of the new home page for

The impressive building in the photo is not the math department.
The building is actually Columbia's Butler Library.
"Along the front and sides of the library are inscribed the names of
Homer, Herodotus, Sophocles, Plato, Aristotle, Desmosthenes,
Cicero, Virgil, Horace, Tacitus, Saint Augustine, Aquinas, Dante,
Cervantes, Shakespeare, Milton, Voltaire, and Goethe." —Wikipedia
The inscribed names outline a defense of liberal education
perhaps more robust than the Feb. 26 effort of Andrew Delbanco,
which University Diaries calls "tepid." (See the previous Log24 post.)
"But even if the religious note is dissonant to some of us,
