Yi Gyu-gyeong (Korean: 이규경; Hanja: 李圭景; 1788 – year of death unknown) was a Silhak scholar in the Joseon period from the late 18th century to the mid-19th century who succeeded the accomplishments of Silhak and sought erudition. He was born in Jeonju and his courtesy name was Baekgyu (伯揆). His pen name is Oju (오주; 五洲) or So-un-geosa (소운거사; 嘯雲居士). His grandfather was Editor-Compiler Yi Deokmu (이덕무; 李德懋) and his father was Yi Gwanggyu (이광규; 李光葵).
Yi dedicated his life to writing his own books and reading many books from Korea and China. He was deeply interested in studying astronomy, geography, history, literature, culture, religion, paintings, calligraphy, and customs while remaining out of public office. In particular, he published Oju yeonmun jangjeon sango (Korean: 오주연문장전산고; Hanja: 五洲書種博物攷辨, Random Expatiations of Oju) which was received to be the best encyclopedia in the 19th century. Consistent with analysis and dialectics, his style of writing and academic characteristics gave birth to works of detailed scientific techniques that were distinguished from other works of the Joseon dynasty, contributing to an expansion in the scope of Silhak to natural history.
Yi's studies was influenced by his ancestors. His grandfather, Yi Deokmu, was scholarly and well-versed in the Hundred Schools of Thought. His writings created a new style to describe the heart of the people and social conditions in detail. When King Jeongjo opened the Kyujanggak, he appointed well-known scholars whose duties were to compile, proofread and transcribe books, such as Geomseogwan (檢書官). Yi Deokmu was called the Four Geomseo along with Yu Deuk-gong (유득공; 柳得恭), Bak Jega (박제가; 朴齊家) and Seo Isu (서이수; 徐理修). Yi won the King’s favor. He participated whenever there were letters to compile at Kyujanggak. His son, Yi Gwanggyu, succeeded his father as a Geomseo, serving at Kyujanggak for a long time. Yi Gyu-gyeong was influenced by such family tradition and the Silhak of the Qing dynasty that prevailed at that time.[1]
The late Joseon dynasty, during which Yi Gyu-gyeong lived, saw the development of commerce and handicrafts as the agricultural productivity increased. Active in the mid-19th century, he sought erudition as a new turning point from Neo-Confucianism academic method “Gewu Zhizhi (格物致知)”, which was an epistemological concept of Confucianism that dominated the then society, and academia in the period of transition from agricultural to industrial society. Studying and recognizing objects with Neo-Confucian academic methodology inevitably led to difficulties in obtaining specific information on existing objects and interpreting various phenomena. In particular, as the state-led mining development project broadened to the private sector after the mid-18th century. The boundaries of society-led industries started expanding in all areas, and society posed the need to transition the recognition standard of the subjects who recognize social issues. Among them, the pursuit of encyclopedia-based studying and the borrowing of the erudite academic method were of interest to Silhak scholars who tried to suggest various academic turning points, noting the changing social conditions at the time. Yi defined his academic identity as erudition and continued. His erudition did not simply mean “having extensive knowledge”. He tried to recognize objects and issues accurately and firmly in many ways[2]
Yi inherited numerous books and reading notes accumulated by his grandfather and father. Based on them, he pioneered a wider academic world. From what is now known, there are traces of continuous writing from 1800 to 1855. In particular, his book Oju yeonmun jangjeon sango is a 50-year-long masterpiece which was amended and supplemented until just before his final breath. It represents the early and mid-19th century books.
The list of Yi's books shows that he had a wide range of interests and concentrated on editing practical books. Of course, even though he did not personally experience and experiment in various fields, but he did organize the books of Silhak for future generations to use which were in fashion in the early Joseon dynasty. He also organized professional technical books of the Ming and Qing Dynasties, and books written by western missionaries. By doing so, he made great achievements in providing the basis for information aggregation and scientific analysis methods.
Yi left nearly twenty books including his masterpiece Oju yeonmun jangjeon sango. This focused on the compiling of practical books rather than on the traditional Confusianism, and gathered the knowledge of those days in encyclopedia style.[3]
Yi is regarded as an erudite scholar who flourished Silhak in the late Joseon dynasty Silhak by succeeding Silhak accomplished by his grandfather Yi Deokmu, without holding a government post during his lifetime. He compiled various specialized books, including Oju yeonmun jangjeon sango, known as the best encyclopedia of the 19th century. He opened up the horizons of Korean erudition by organizing information on all creation of those days in an encyclopedia. It is meaningful in that it set an example of the erudite study of ancient documents by freely studying, categorizing and describing objects in a vast but systematic manner, freeing from the existing Neo-Confucian reasoning method.[4] The new knowledge and innovative ideas that Yi suggested so that they could be widely communicated to objects of all ages and countries seem to have been seriously and desperately accepted by early enlightenment leaders.[1]
