礼学，既是一个对象，也是一个视角；既是一个范围，也是一个领域。礼学在历史的发展过程中，在礼学家的著述中，呈现出一种解说与论证的多样化学术形式和学术诉求。其与各种思想表达的连接，也有不同的呈现。这是在本书所作的个案考察和论述中所能够看到的。本书选取了魏晋南北朝以降至于宋明一些重要的礼学人物，以八章的规模，或集中或分别地加以考察和论述。首先是王肃、熊安生和皇侃的《礼记》学，以及唐代孔颖达对他们学说的引述和评议，包括后世学者的评价等等方面的研究，即成为第一章的内容。而后将时代跨越到宋代，即李觏、王安石、程颢、程颐、朱熹的礼学思想，分别成为第二章至五章的论述内容，其中，礼学所承载的政治理想、变法实践，以及形而上的理论建构，还有礼学文本体系的重构及对家族之礼的重视，可以说是两宋礼学代表人物的学术与思想之博大精深的体现。吴澄、方孝孺、黄道周，是元明时期礼学著述和思想表达的代表人物，他们的篇章著述与学术思想的表述形式各不相同，本书最后三章选取其特点鲜明的礼学篇章进行考察分析，以呈现其不同样式的礼学思想风貌。

Etiquette, both an object and a perspective; It is both a scope and a field. In the process of historical development, the study of etiquette presents a diversified academic form and academic appeal of interpretation and argument in the writings of etiquette scholars. Its connection to various expressions of ideas is also presented differently. This can be seen in the case studies and discussions made in this book. This book selects some important liturgical figures from the Wei, Jin, Southern and Northern Dynasties to the Song and Ming dynasties, and examines and discusses them in the scale of eight chapters, either intensively or separately. The first is the study of Wang Su, Xiong Ansheng, and Huang Kan's "Book of Rites", as well as Kong Yingda's quotations and comments on their doctrines in the Tang Dynasty, including the evaluation of later scholars, which became the content of the first chapter. Then, the era spanned to the Song Dynasty, that is, the ideas of Li Xiao, Wang Anshi, Cheng Hao, Cheng Yi and Zhu Xi became the discussion content of chapters 2 to 5 respectively, in which the political ideals, the practice of changing the law, and the metaphysical theoretical construction carried by the etiquette studies, as well as the reconstruction of the text system of the etiquette and the emphasis on family etiquette, can be said to be the broad and profound embodiment of the scholarship and thought of the representative figures of the two Song Dynasties. Wu Cheng, Fang Xiaoxiao, and Huang Daozhou are representative figures of liturgical writings and ideological expression in the Yuan and Ming Dynasties, and their chapters and academic ideas have different forms of expression, and the last three chapters of this book select their distinctive liturgical chapters for investigation and analysis to present their different styles of liturgical thought.（AI翻译）
