Seo Yu-gu (; 1764âÂÂ1845) was a Korean Neo-Confucian scholar, agricultural administrator and encyclopedist in the Korean Joseon Dynasty. His pen name was Pungseok (), his courtesy name was Junpyeong (), and his posthumous name was Mungan (). He came from the Daegu Seo clan ().
He was born at Jangdan, Paju, Gyeonggi-do in 1764. At that time, the practical science called Silhak () was prevalent among the Joseon intellectuals, but unfortunately, it was rarely adopted by the Royal Court. He authored the huge 113 volume encyclopedia, Imwon Gyeongjeji () for more than 30 years from 1806. Though the series of Encyclopedia Koreana on Rural Living were not published in his lifetime, Seo Yu-gu wished to share with fellow gentlemen how to live a wonderful living in the country.
Seo Yu-gu's family history was highly respectable. His great-grandfather was Seo Jong-ok () who served as the minister of interior. His grandfather was Seo Myeong-eung (), who was the head of the Royal Academy. His father, Seo Ho-su (), also served as the minister of the interior. He was adopted to his uncle Seo Cheol-su ().
Following his family tradition, Seo passed both the state examination and the king-ordered specific selection test () in 1790, and was appointed as the country governor in rural areas.
Like his father and grandfather, both of whom were interested in agriculture and farming and authored some agricultural books, Seo collected a lot of books about agriculture at home and from China. While staying at Sunchang, Jeolla-do, he made a suggestion to King Jeongjo that agricultural specialists should be stationed to each province to research and experiment indigenous farming technologies of the country and the whole collection of such research results be published to help and educate farmers and citizens in the country. Though his suggestion was not adopted by the Royal Court, it was the beginning of his own encyclopedia.
In 1806, when his uncle was expelled from the government as an accomplice of treason, Seo Yu-gu went into a self-imposed exile. He stayed in his farmland for 18 years. Later, returning to the capital city, he served as the minister of interior, minister of finance and the chief of the Royal Library.
In his self-imposed exile, Seo came back to his hometown at Jangdan and practiced farming and fishing, sometimes making food and rice wine by himself. For more than thirty years, he was engaged in writing and editing the volumes of his life's work with one collaboratorâÂÂhis son. Upon completion, Seo tried to publish the whole series without success. He died at the age of 82.
In a word, Imwon Gyeongjeji could be applied to the daily life of not only ordinary Confucian gentlemen but also peasants in the country.
The Encyclopedia Koreana on Rural Living is the life-long works of Seo Yu-gu who successfully incorporated his knowledge and experiences into his own framework of informed encyclopedic volumes based on hundreds of references from Korea as well as China. As he made a careful citation, the readers could made a list of all references some of which are not available today. This book provides resources for the study of Korean history of science and technology, particularly agricultural technology. The author's understanding of environmental connections between heating systems, forest degradation and bare mountains display a holistic analysis of landscape. His historical approach to the development of costume led to suggestions of adaptation for the sake of daily practicalities.
The 113-volume Encyclopedia Koreana on Rural Living contains 2,520 thousand Classic Chinese characters and 28 thousand items in 16 areas.
Notwithstanding the practical nature of the books, the author was not affluent enough to publish the huge volumes at his own expenses without any subsidy from the government. At that time, few bureaucrats could acknowledge the practical value of his works.
So there remain only three copies: original at Seoul National University Gyujanggak Library (), one copy at Korea University Library. Another copy maintained by Seo family clan is preserved at the Osaka City Library.
Only a part of the works have been translated into Korean and published step by step in a series because of financial constraints. Their first introductory book Imwon Gyeongjeji was published in June 2012 by Sower Publishing Co.
This project for translation and publication of Imwon Gyeongjeji has been staged by the Imwon Gyeongje Institute () founded by Jeong Myung-hyun and his fellow researchers in March 2008.
The speed of work in this project is very slow because most of participants are part-timers. For example, in 2015, they hosted an experimental event in association with Pungseok Cultural Foundation (). Their purpose was to prove that Seo was a great chef by actually making several dishes as illustrated in Imwon Gyeongjeji.
Contrary to the prevailing trend of the learned in the 19th Century, Seo Yu-gu studied and collected books and materials of practical use like what to eat, what to use, where to live, how to enjoy hobbies in a daily rural living. He criticized his fellow gentlemen who were inclined to the conceptual or literary works and Confucian classics. He mocked that they liked to speak of conceptual meals of soup cooked with soil and cakes made of papers (), Instead, he recommended a practical approach to becoming well and prosperous in rural life.
Thus far, his works have not seen full publication. Firstly, the entire series is too big to be easily copied and translated into plain Korean. Secondly, there is a famous scholarly rival of the same time named Dasan Jeong Yak-yong (), whose works have been widely translated into Korean and other languages.
