半坡遗梦杜爱民

遗址考古的目的是为了发现。考古学的分类方法、对现场清理发掘的注重、以及放射性断代技术的应用,都是为了对发现实施谱系化的步骤和方法。近些年,考古发现的目的越来越多样化。对考古的期待也像是对消费的期待一样,成了永远填不满的无底洞。考古发现被拿出来展示的东西,不外乎是一些质地、工艺、规制的性价比。这是一种奢华的倾向,物质的崇拜,具有我们身处的这个时代的明显特征。

在这样的语境里,半坡的沉落是可想而知的。作为新石器时代仰韶文化母系氏族典型的聚落,被考古界称为仰韶文化的半坡类型,实际包括了半坡和姜寨两个遗址,所出土的器物主要是生产工具、生活用具和艺术品,建筑和设施多为房屋,窑穴、陶窑、墓葬;器物除了取自天然的石、骨之外,最具代表性的便是陶器,以粗质和细泥的红色、红褐色陶为主,粗砂者居多。

可以用单纯来描述半坡的一切。陶罐、小口尖底瓶、钵、盆、碗,甑的器表,只是绳、线、指甲、弦的纹型。色彩也是单一的。是陶本身的红褐和天然的墨黑线描;圆钵口沿的宽带纹上,刻划有二十二种不同的符号,就像是呼吸自然沉落在上面,不着丝毫的痕迹,它们被认为是中国古代文字的渊源之一,其后东方伟大的杰作概源于此。

惊人的东西无比单纯。半坡的彩纹只有人面、鱼、鹿,植物等象生性花纹和三角形、圆点组成的几何图案,它们是形式最基本的元素。就连环、璜、珠、坠,以及耳饰,发饰、镶嵌饰,都是石、骨、陶、蚌磨制而成的。用来鞣制兽皮的工具,是一种制成颗粒状麻面的陶锉。尖底瓶印证出了重心原理。瓶子只要一接触水面会自动倾斜,灌满水后又因为中心移动而自然竖起。这些器物是心和体温的结晶,由大地的元素泥土制成,而不是技术、工艺和机巧堆砌成的块垒。知识技术的缺位,丝毫不影响和减损价值的含量。风吹过粗砂的陶罐嗡嗡有声。这是制陶人的响应。心灵和体温在这里需要的是对心灵和体温的挽留、回应。

彩陶上描绘最多的动物是奔走的鹿,爬行的鼋和伫立的鸟,浅翔的鱼。均是劳动中的所见。平展的侧面形象,直线造型,比例准确,形象写实。人面纹是一种特例。有两种鱼与人面的奇特结合:一为与寓鱼于人面的复合形象。人面的嘴,两旁对称,各衔一鱼,人嘴外轮廓与鱼头构成共鱼形;另一为人面寓于鱼的复合,鱼纹头圆框中植入适合形的人面图像。所谓的"高级"造型艺术,现如今也莫过如此。

在半坡绘画中,看不到标榜与卖弄。内心的反映是什么,便是什么;感受是什么,就是什么。这种鱼人结合的形象,是人和自然有灵之物的相互寄寓和转借,是与自然的交融与共同。被人格化的鱼类图像和各式鱼类图纹是半坡先民的图腾。是氏族的保护神。是惧怕、担忧和敬畏。这些也许就是写意和抒发吧!竟然可以来得如此厚道和平易近人,足以让艺术的洋奴心态,无地自容。

半坡绘画,最初并不是被当作艺术品创作出来的,它们只是劳动中的感受和劳作者的想法,是一种自然状态必然形成的结果,不是自为的有意制作。艺术根本不是通过学习就能够得来的。艺术是天性,是身体自身固有的授予。学习可以积蓄,可以启示和萌发、擦亮艺术的天性,但不是天性本身,不可替代天性。在半坡,这天性不是什么高深的学问,尊贵的智性,贵族或什么东西自己有而别人没有的优越感觉。这天性是人人皆有的厚道本身,是平易亲近的感觉。在半坡,有可能人人都是艺术家,都是知识分子,前提是你要愿意,并且持续不断地去做。

半坡人把死去的婴孩埋放在居住的房子附近。大人们把婴孩的尸体放在大陶瓮或罐里,上面盖着陶钵或陶盆,并在当中凿个小洞,供孩子的亡灵进出,便于回到家里。较大的孩子则用两个陶瓮对接起来埋放,表示父母对孩子的眷恋之情。尽管自然条件恶劣,生活艰苦,半坡人是乐生的。有了陶泥作成的甬道,死亡就不再是一道界线。灵魂可以在其间自由出进。

没有黄金的材质,没有等级,也不见欲望。半坡只有遗梦。只有梦,才能让身体和心灵安睡。

A.在半坡,只要在劳动中有感受和想法,并且愿意表现出来,就有可能创作出有艺术价值的绘画作品来。

B.半坡人在绘画中自然地流露出了对鱼的崇拜,表现出一种艺术的天性。

C.半坡人以浪漫的形式埋葬孩子,乞求他们能早日进入极乐世界。

D.半坡文物没有黄金的材质,没有等级,也不见欲望,这让我们看到了半坡人不重视实的内在特征。

单项选择题

Soon after his appointment as secretary-general of the United Nations in 1997, Kofi Annan lamented that he was being accused of failing to reform the world body in six weeks. "But what are you complaining about" asked the Russian ambassador. "You’ve had more time than God." Ah, Mr. Annan quipped back, "but God had one big advantage. He worked alone without a General Assembly, a Security Council and [all] the committees."

Recounting that anecdote to journalists in New York this week, Mr. Annan sought to explain why a draft declaration on UN reform and tackling world poverty, due to be endorsed by some 150 heads of state and government at a world summit in the city on September 14th-16th, had turned into such a pale shadow of the proposals that he himself had put forward in March. "With 191 member states", he sighed, "it’s not easy to get an agreement."

Most countries put the blame on the United States, in the form of its abrasive new ambassador, John Bolton, for insisting at the end of August on hundreds of last-minute amendments and a line-by-line renegotiation of a text most others had thought was almost settled. But a group of middle-income developing nations, including Pakistan, Cuba, Iran, Egypt, Syria and Venezuela, also came up with plenty of last-minute changes of their own. The risk of having no document at all, and thus nothing for the world’s leaders to come to New York for, was averted only by marathon all-night and all-weekend talks.

The 35-page final document is not wholly devoid of substance. It calls for the creation of a Peacebuilding Commission to supervise the reconstruction of countries after wars; the replacement of the discredited UN Commission on Human Rights by a supposedly tougher Human Rights Council; the recognition of a new "responsibility to protect" peoples from genocide and other atrocities when national authorities fail to take action, including, if necessary, by force; and an "early" reform of the Security Council. Although much pared down, all these proposals have at least survived.

Others have not. Either they proved so contentious that they were omitted altogether, such as the sections on disarmament and non-proliferation and the International Criminal Court, or they were watered down to little more than empty platitudes. The important section on collective security and the use of force no longer even mentions the vexed issue of pre-emptive strikes; meanwhile the section on terrorism condemns it "in all its forms and manifestations, committed by whomever, wherever and for whatever purposes", but fails to provide the clear definition the Americans wanted.

Both Mr. Annan and, more surprisingly, George Bush have nevertheless sought to put a good face on things, with Mr. Annan describing the summit document as "an important step forward" and Mr. Bush saying the UN had taken "the first steps" towards reform. Mr. Annan and Mr. Bolton are determined to go a lot further. It is now up to the General Assembly to flesh out the document’s skeleton proposals and propose new ones. But its chances of success appear slim.

According to the last paragraph, the General Assembly ()

A. is deleting the document’s skeleton proposals

B. is determined to go further toward disarmament

C. is attempting to put forward new proposals

D. is unlikely to work out relevant details and advance novel proposals
