一、“我是一个中国人”1980年10月,《北京文学》杂志发表了一个短篇《受戒》,人们开始注意到一个陌生的名字:汪曾祺。及至《大淖记事》等小说接连刊出之后,人们便都记住,并且喜欢上了这位“年轻”的老作家。汪曾祺1920年3月5日出生于江苏高邮的一个地主家庭。他三岁丧母,两位继母对他都很好。汪曾祺在家中是个“惯宝宝”。父亲是一位画家,擅长花鸟写意,在当地颇有名气。在这样一个富足、温暖的书香家庭出来,他从观念到性情,自然脱不掉传统文化的影响。

1乡下人贫穷,闭塞,一生过着庸常的日子。在低矮的屋檐下,很难冒出一个可以称为骄傲的人。在我们村子,宗元可能是仅有的一个。宗元身材高大,黄铜色皮肤,肩膀多出两块隆起的肌肉,显得特别健壮。他活到快七十岁,一直留着青年小分头,有一搭头发老是落在前额上,得不时地伸手抹一下,那动作却是出奇地柔缓。

精神性存在于现实世界的非物质领域中,它滋养人类的灵魂,让人类在生存中寻找根本的价值和意义,并以此发展自身的精神生活。精神的形态,决定文学的形态、结构和品质。比较世界文学,中国文学的精神性是匮乏的。唯有五四时代,文学洋溢着自由精神、反抗精神、战斗精神。失去了五四精神,就失去了新文学的生命。在新的历史境遇里,除了强制性因素之外,还充斥着景观社会、物质主义的各种挑战和考验,所有这些,对于以精神为生命的文学来说都是致命的。'我们是谁?我们从哪里来?我们到哪里去?'这仍然是一个问题。中国文学呼唤着精神还乡,返回到人的存在上来,回到新文学的源头里来,重振五四时代'人的文学'的精神。
