在《易》类书籍标点中,六十四卦卦名是否应加书名号,各书观点不一,莫衷一是。现行《周易》由《经》和《传》两部分构成,《经》指《上经》和《下经》,《传》指《上彖》、《下彖》、《上象》、《下象》、《上系》、《下系》、《文言》、《说卦》、《序卦》、《杂卦》十篇。《上下经》为六十四卦总名,可加书名号;六十四卦为经文之正文,可不加书名号。其实六十四卦卦名作为专名更早于篇名,专名之义更广于篇名之义。若加上书名号,则六十四卦违离卦名取义于卦象之原理,于《易》源于象之旨远矣。在通行《周易》各本中,六十四卦卦名多在目录中出现。这种做法只是为了方便读者检索,并不等同于篇名。六十四卦卦名勿须加书名号。
There are different ideas about whether there should be punctuations for the 64 divinatory symbols in books like "Book of Change". The current version of "Book of Change" is composed of two parts : "Divination" and "Annotation". "Divination" includes "Upper" and "Lower" parts,which are the general divinatory symbols, so it is suggested to use "title identifiers" while the 64 pieces of divination are the content of "divination" so "title identifiers" are not necessary. If they are marked with the "title identifiers" it will break the philosophy of making inference from the symbols. In the current version of "Book of Change" ,the 64 divinatory symbols usually appear on the list of table of contents for the convenience of searching hut they are not the titles so they should not be marked with "title identifiers".
