2010年11月分記事へのエム・ワイ君の感想 (M.Y.'s Comments on November-2010 Articles)

In Japanese only

 M.Y. 君から "Ted's Coffeehouse 2" 2010年11月分への感想を12月28日付けで貰った。同君の了承を得て、ここに紹介する。青色の文字をクリックすると、言及されている記事が別ウインドウに開く。




1. 「核なき世界へ:被爆国からのメッセージ」(11月8日付け記事の "From tweets of yesterday" 中)

朝日紙連載「核なき世界へ:被爆国からのメッセージ」に学ぶべき言葉が多い。11月6日付け、月下美紀氏「地上戦を経験した沖縄の人々は広島、長崎に関心を示さない。…中略…『戦争反対』を根底に据えることで、…中略…一緒に考えることができるのではないでしょうか。」11月7日付け、アーサー・ビナード氏「核抑止論はナンセンス。…中略…オバマ氏も見かけ倒しの『チェンジ!』ではなく、命がけでやれば方向転換出来るはずです。そもそも人間が作ったモノをなくすのだから、やる気があれば可能でしょう。

と筆者は、7回にわたる「被爆国からのメッセージ」の中から肝要な言葉を抽出しています。

 オバマ大統領のやる気について、朝日新聞(12月24日付け朝刊)は、米上院が22日、米ロの新戦略兵器削減条約(新START)の批准を承認し、ロシア下院は24日にも批准承認する見通しであり、オバマ氏はこの批准承認後にホワイトハウスで記者会見し、「過去20年間で最も重要な軍縮合意だ。われわれはロシアとともに核兵器を削減する」と語ったことを報道しました。一方で、「核なき世界」に向けて米国が取り組むべき課題も山積しており、オバマ氏はそのために国内政治との相克をどう乗り越えるのか、答えは見えてこなくて、「次の一歩議会が壁」、と解説していました。時間がかかっても、大きな目標に向かい着実に努力し続ける限り、理性ある世界では、核兵器を使用した壊滅的な戦争は回避できるのではないでしょうか。

2. 京大11月祭

 昨日、私は妻と第52回京都大学11月祭を見に行った。会場で長女の家族と落ち合う。今年同大学へ入った孫の一人が、吉田グラウンドでソフトボール部の仲間たちと豚汁の模擬店を出していたので、一杯食する。食べ物を中心に多数の模擬店が並び、大音声でスピーカーから音楽が流れている様子は、私の学生時代と比べて、大いに趣きを異にする。

と筆者は書いています。なるほど。

 私は3回生の時、理学部3、4回生が合同で「11月祭の合唱へ」との募集に応じました。企画、指導、指揮は物理4回生のMさんで、練習は、昼休憩時間に校舎の前の空き地で行うことで、夏前から始まり、合唱曲は「シベリウスのフィンランディア」などでした。このブログで紹介のあった真木和美君は、歌も好きで高い独特の美声を持ち、高音部を歌いました。歌詞は日本語で、比較的簡単なメロディーでしたが、Mさんは「この歌の本式のものはとても美しい。頑張りましょう」と皆を励ましました。この合唱曲は、交響詩「フィンランディア」の中間部に歌が付けられたものです。フィンランドがロシアの圧制から独立を勝ち取った時、この交響詩「自然の美を賛えるフィンラディア」は、国の自由を象徴する存在になりました。

 私はずいぶん後になってこの合唱付き交響詩を聴き、素晴らしい曲だ、あの時はこんなに由緒ある名曲を歌ったのか、と感銘を受けました。当日は、時計台下の講堂で、大勢の聴衆の前で歌いました。京大交響楽団の演奏が音楽会をしめくくりました。また、3回生か4回生か定かではありませんが、文化祭の時に吉田分校の運動場で、ラテン音楽の演奏があり、壇上に平沢興総長が招き上げられて、団員と肩を組んで、「小さな星:Estrellita、コンドルは飛んでいく:El condor pas」 などの馴染み深い演奏に興ぜられ、愛嬌のある一面が見られました。——学園祭についてこのような記憶が甦りました。

3. 秋色、他

 イロハモミジ、サクラ、京都・東大路のイチョウ並木、ハゼノキ、コバノズイナ、ハナミズキ、カエデ、ベニスモモ、団地、校庭の紅葉など、無意識に見過ごしがちな、秋の美しい彩りに気付かせて貰いました。何気ない日常の自然の美しさを感じる心のゆとりを持ちたいものです。「竹田城跡と立雲峡へのバス旅行(4月)」に関連して、YouTube ビデオ 朝霧に浮かぶ「天空の城」が11月5日付け記事に引用されているのを見て、感動しました。

網に写る影 (Shadows on the Net)


 上掲の写真は近くの高校の運動場の金網塀を撮ったものである。金網塀の内側に、もっと目の細かい網が吊り下げられている。それでも外からは、運動場がかなりよく透けて見えるのだが、網の向こうに木や校舎があるところでは、網の緑色が濃くなり、透明性が減って、陰の部分を作っている。その部分に、右斜め上からの日光によって、さらに黒っぽい木の影が重なり出来て、そこでは透明性が回復している。——これは、そういういう面白い光景である。内外の網の破れ目などもあって、注意深く見ていると、しばらく見飽きない。(2010年12月10日撮影)

The photo above shows the fence of the playground of the senior high school near my house. It is made of wire netting. Inside the fence, a sheet of finer netting is hung. From the outside, we can see the playground fairly well through the nets. Where school buildings and trees stand beyond, the internal net become darker green, reducing the transparency and forming the shade regions. Onto those regions, the sunlight from upper right projects the much darker shadows of trees, and transparency is restored there. — This is such a fascinating spectacle. Carefully looking at this photo, I also find rents on both the inner and the outer net, and do not get tired of scrutinizing the image for a while. (The photo was taken on December 10, 2010.)

薄明光線 (Crepuscular Rays)


 一昨日、上掲の写真に向って右側の光景を撮った写真を掲載し、そこに見られる放射状の光の筋の集合を何と呼べばよいかという疑問を記しておいた。これに対して、一人の方からコメント欄で「天使の梯子(はしご)」、「レンブラント光」、それに「雲間からの光芒」(彼自身が使用しているもの)という呼び方を教えて貰った。

 そこで、「天使の梯子」でインターネット検索をしたところ、『ウィキペディア』 の「薄明光線」の項[2010年11月13日 (土) 21:43]が見つかった。これが気象現象としての名称で、一般的には「天使の梯子」がよく知られている、と説明されている。そして、他に「天使の階段」、「ヤコブの梯子」、「レンブラント光線」、「光芒」の名も挙げてある。

 ヤコブの梯子、天使の梯子という名称は、旧約聖書創世記28章12節に、ヤコブが夢の中で、雲の切れ間から差す光のような梯子が天から地上に伸び、そこを天使が上り下りしている光景を見たという記述があることに由来するそうだ。また、レンブラント光線という名称は、レンブラント (1606–1669) がこれを好んで描いたことに由来するという。

Two days ago, I posted a photo of the scenery at the right of that of the above photo and wrote the question what we should call a group of radial light-rays seen there. In reply to this, one person wrote in the comment column the following names: "天使の梯子 (angel's ladder)," "レンブラント光 (Rembrandt ray)" and "雲間からの光茫 [light beams through gaps in clouds (the commenter's own words)]."

Thus, I made an Internet search of "天使の梯子" and found the page "薄明光線 (crepuscular rays)" of Wikipedia [Japanese edition, 13 November 2010 at 21:43]. The phrase "crepuscular rays" represents the atmospheric phenomenon just in my photos of Tuesday and today. According to the above Web page, crepuscular rays are better known by the name of "angel's ladder" [in Japan], and other names of this phenomenon are "angel's stairs, angel's stairway," "Jacob's ladder," "Rembrandt ray" and "light beams."

The names "Jacob's ladder" and "angel's ladder" come from the following description in the Book of Genesis (28:12): Jacob dreamed that there was a ladder set up on the earth, and the top of it reached to heaven, like the light beam through clouds; and the angels of God were ascending and descending on it [adapted from "Jacob's ladder" page of Wikipedia (English version, 5 December 2010 at 22:08)]. The name of "Rembrandt ray" comes from the fact that Harmenszoon van Rijn Rembrandt (1606–1669) liked to draw crepuscular rays.

映画『ブロンド少女は過激に美しく』 (The film "Eccentricities of a Blonde-haired Girl"

 昨日、阪急電車・十三駅の近くにある第七芸術劇場という映画館まで出かけて、私の好むマノエル・デ・オリヴェイラ監督の『ブロンド少女は過激に美しく』を見て来た(この映画の撮影中に、同監督は100歳になったそうだ)。

 時刻あるいは季節を変えて何度か映し出される海岸の街・リスボンの全景の美しさや、文化的な社交の場の様子などは、はるばる見に来たかいがあったと思わせるものだった。64分の中編なので、終わったときは、いささかあっけない感がしたが、これは結論的な印象ではない。結末につながる伏線が早くにありながら、観客は間もなくそれを忘れさせられ、結末にいたって思い出させられる、という繊細なプロットが巧みに映像化されていたことを振り返ってみると、この映画の注意深い技術と味わい深さに気づく。

Yesterday, I went to the Seventh Art Theater near Juso Station of Hankyu Railway in order to look at the movie "Singularidades de uma Rapariga Loura (Eccentricities of a Blonde-haired Girl)" directed by one of my favorite directors, Manoel de Oliveira (we hear that he became 100 years old during the making of this film).

Panoramic views of the coastal town Risbon, at different times or seasons, repeatedly shown, were so beautiful and cultural atmosphere of the social occasion included in the story was so smart to make me think that it was worthwhile to come to see this movie all the way. I got a little bit of anticlimactic feeling when this film of only 64 minutes finished, but this was not the decisive impression. In the earlier part of the story, there was a foreshadowing event, but we are forced to forget about it, being reminded of it by the final episode. Looking back that such an intricate plot was finely depicted, we perceive the meticulous technique and rich flavor of this film.

光の何? (What of Light?)


 この写真のような空の光景を見て、中学生だった頃の私に、「光のしまが見えるよ」といったのは母だったか、あるいは、伯母だったか。そのとき私は、「しま」を「島」と受け取り、いささか妙だが、雲間あるいは雲の中の明るい部分を、海に浮かぶ島に見立てての詩的な表現だと思った。しかし少し後で、それは何本もの光の筋が暗い部分を挟んで並んでいる様子を指しての「縞」だったと気づいた。「縞」はおおむね並行に走る模様をいうので、このように放射状である場合、それを指していることが、聞いた瞬間には分かりにくかったのだと思う。それでは、このような光の模様を何と呼べばよいのか。「放射状の光線の束」というような長たらしい表現になるだろうか。

Pointing to the sky as seen in this picture, my mother (or was it my aunt?) said to me, "We see shima of light there." It was probably in my junior high school days. At that time, I thought that she meant "island" by shima (one of the meanings of the Japanese word shima is "island") and that it was a poetic expression of the bright areas among or in the clouds, likening them to the islands in the sea, though it sounded a little strange. However, I noticed soon later that she had referred to the light rays with dark portions among them (another meaning of shima is "stripes") The "stripes," however, commonly run in parallel. Perhaps, this made it difficult for me, at the moment of hearing them, to realize that her words referred to the radial pattern. Then, what is the suitable expression for the pattern of light rays as seen here? Is it such a lengthy expression as "a bundle of radial light rays"?

サントリー1万人の第9 (Suntory Presents Beethoven's 9th with a Cast of 10000)


 昨日、妻と大阪城ホールへ表記の演奏会(第28回)を聞きに行った。娘の一人が1万人の合唱メンバーに参加したのである。オープニングで「Japanese Soccer Anthem(日本サッカーの歌)」が演奏され、プログラムの第1部には歌手・平原綾香が登場し、「Jupiter」、「威風堂々」、交響曲第9番第3楽章にオリジナル歌詞をつけた「Love Story」、そして「Joyful, Joyful」を歌った。第2部が交響曲第9番である。総監督を務めた指揮者・佐渡裕は今回の公演のテーマとして「野性味」を考えたそうだが、合唱部分では、それが十分に発揮された力強い歌声が広いホール一杯に響いた。最後に聴衆も加わって「蛍の光」の合唱があり、午後3時から始まった演奏会は、午後6時近くに、文字通り全員の歓喜のうちに終了した。会場を出ると、ライトアップされた大阪城が夜空にくっきりとした姿を見せていた(上掲の写真)。

Yesterday, I went to the Osaka Castle Hall with my wife in order to listen to "Symphony No. 9 with a chorus by ten-thousand people (the 28th)." One of our daughters took part in the chorus. At the opening, "Japanese Soccer Anthem" was played. In Part I of the program, Ayaka Hirahara joined to sing "Jupiter," "Pomp and Circumstance," "Love Story" (her original lyrics for the third movement of Symphony No. 9) and "Joyful, Joyful." Part II consisted of Symphony No. 9. Conductor Yutaka Sado, who was the general director of this event, chose "wild style" as the concept of this year's performance, and the voice of the chorus strongly sounded just with the flavor of these words to the every corner of the big hall. At the end, the audience also joined the chorus of "Auld Lang Syne." The concert, which had begun at 3 o'clock, closed a little before 6 o'clock with the joy of all the participants. Going out of the hall, we saw the lighted tower of Osak Castle clearly in the night sky (the picture above).

About Peace and Politics

NHK ニュースは最近、政治家の発言について「認識を示した」という言い方をする。日常使わない固い表現である。「考えを述べた」ではいけないのか。——と思っていた矢先、『図書』12月号に丸谷才一が長谷部恭男著『憲法の imagination』中の「認識を示す」という文を紹介しているのを読んだ。長谷部は、「あたかも価値判断を全く含んでいないかのように装いつつ、実は特定の価値判断を前提として人々の行動を一定の方向に誘導することにこそ、『認識』は示されている」と論じているという。これを読むと、「認識」という語の発生源は NHK でなく、政治家たちのようだが、そうなのだろうか。

先のツイートが肯定されるならば、私が好ましくないと思った NHK ニュースの言葉遣いの責任は、政治家たちにあることになりそうだ。しかし、この言葉遣いの発端が政治家たちにあるにしても、「認識を示した」という報道語は、政治家の発言引用の外にある。つまり、毎回のこの形の報道内容において、政治家自身が「認識」の語を使ったかどうかは明らかでない。したがって、長谷部によるこの語の意味からすれば、客観的に報道すべき NHK が、人々の行動を一定の方向に誘導しているという疑いが残り、やはり好ましくない言葉遣いであることになる。
