Case-based recording and discourse of philosophy also was a target for compilation. Similar to how medical knowledge had a prototypical template for future works, Huang Zongxi's writings in the field had largely served a similar purpose. However, despite popular discourse among scholars of this era, philosophical writing had suffered immensely from two problems. Firstly, was a lack of clear definition regarding philosophical writings as a whole, giving rise to two separate, but equal definitions. "Archival" would mean that the philosophical work would be defined as a scholarly article. Whereas, "cultural" would mean the literature would be rearranged as a Buddhist Kōan, though any writing presented this way would be interpreted in a more literal fashion as compared to the traditional rhetorical question. Chinese philosophical writing's other problem at this time would be a lack of bibliographical classification, largely in part due to authors and previous compilers not considering any philosophical work as part of a historical record. As such, compilers for the "Siku Quanshu" redefined the classifications of several compilations that made it into the published copies, and set boundaries based on the author's biographical history and intent of their writing in an attempt to remedy these dilemmas.
