本文认为,北京大学择定“盛唐工程”为跨世纪的重点项目是很有眼光的,其《盛唐研究丛书》第一辑的出版就相当成功。理由有三:第一是选题好,第二是操作方法得当,第三是设计合理。同时,本文也就其中的一些具体问题提出了切实的商榷意见。从推进唐研究的宏观角度出发,本文进一步对近几十年流行的历史观进行了重新思考,提出了“快乐历史”的新理念及其建设性的具体意见。 This paper argues that Peking University chose “Tang Dynasty Project” as a key project of the new century with a great vision. The publication of the first series of “Tang Dynasty Study Series” was quite successful. There are three reasons: the first is the topic selection is good, the second is the method of operation properly, the third is the design is reasonable. At the same time, this article also put forward some practical advice on some of the specific problems. From the macro perspective of advancing Tang’s research, this article further re-examines the popular view of history in recent decades and puts forward the new concept of “Happy History” and its constructive concrete opinions.
