  • This study purports to explore the possibility of establishing the theory of ethics education based on the concept 'Gyeong(敬)' in Early Confucianism. There was a negative viewpoint on Confucianism directly after the modernization of Korea. However, a positive trend for Confucianism has emerged in almost all sorts of studies even though the results of the studies in Moral education are not always successful. West moral education theories and traditional ethics education theories should be integrated dialectically so that traditional ethics education may be updated. Recently a reappraisal of traditional values has been undertaken as a replacement of liberal democracy values. Faced with the modern civilization's crisis and a decline in morals in Korea, reverence needs to be dealt with in ethics education. This study is primarily concerned with the nature-transcendental relation whose concrete concept is 'Gyeong(敬)' in Confucianism. And the study attempts to put forward the theory of reverence-centered ethics education. The contents of the study consists of the substance of 'Gyeong(敬)' in Early Confucianism, and practical principles and methods of reverence-based ethics education. Some tasks of moral education are also suggested for the scientific establishment of reverence-centered ethics education.

  • This study attempted an eco-ethical approach to the sporting body, focusing on Toegye's Gyeong. A causes for the conflict between man and nature is a wrong view of nature derived from human desire. Toegye thought that the problem of desire could be overcome through Gyeong. Eco-ethical approaches of Toegye's gyeong thought are possible for the following reasons: First, because Toegye's gyeong is completed in nature. Second, because Toegye's gyeong emphasize human responsibility (consideration) for nature. Third, because gyeong is related to the ability to practice morality. Meanwhile, Toegye understood 'preserving the body well' as self-preservation and at the same time, as the meaning of a natural principle of following the laws of nature. From this perspective, the sporting body has meanings of physical fitness and mental health and at the same time, an aspect of ecological values of understanding man and nature as a single network and following the order of nature. Acquisition of Gyeong through the sporting body suggests the practice of 'gyeongsin (respect for the body)' and 'hwalgyeong (preservation of the ecological environment).' When human beings do physical exercise with nature, they proceed to the stage of building up the virtue of yosan yosu (finding happiness in mountains and water) through nature preserving the ecological environment (hwalgyeong) beyond staying at the stage of gyeongsin.

  • Hanhweon-dang Kim Goeng-pil(1454~1504) sublimated ethics whose lead was opened up by Jeong Mong-ju in late Goryeo as one scholarly tendency. Kim Goeng-pil was called 'the father of ethics in Joseon' and has been respected as a model of ethicist for 400 years since then. Following Kim Goeng-pil, Confucian scholars of Joseon cultivated perseverance through Xiaoxue and the perseverance was sublimated to Confucian scholars' energy and then that of state, which served as driving force to keep the national legacy. Kim Goeng-pil suggested how to study with Xiaoxue and sought moral human beings and ethically ideal societies based on strong practicability which is required in Xiaoxue. Individuals' cultivation and social reform are not at a different dimension. Spirit of 'self-cultivation' that Kim Goeng-pil himself demonstrated advanced to pursuit of ethical, ideal state when reaching a level of Jo Kwang-jo. Kim Goeng-pil thought that teaching in Xiaoxue could be achieved through 'Gyeong (敬, respect).' It is the key of Neo-Confucianism in Joseon to control one's mind through the cultivating method of 'Gyeong.' Kim Goeng-pil settled Joseon's Confucianism as 'practical ethics(心學).' Before Kim Goeng-pil, no scholars had well presented the aspects of practical ethics. After King Myeongjong and Seonjo, Confucianism in Joseon worked as the cornerstone of practical ethics. Since mid-17th century, the system of practical ethics had been firmly established with focus on 'Gyeong. Literary men of Kim Goeng-pil and scholars they fostered led the academic and political world of Joseon after mid-16th century. They played the lead in Sarim faction's(士林派) ruling after King Seonjo came to throne. The very foundation which sublimated Joseon to the ethically ideal state and made the Dynasty a 'state of Sarim' was actually laid by Kim Goeng-pil.

  • The purpose of this study was to re-examine the neglected and forgotten Cheongdo Geoyeonjeong, to correct the wrong contents, examine the changes and conditions of the garden, and to establish basic data on the components of the forest in the future. In addition, it was extended to the Gongampungbyeog Cliff, the influence area of the Geoyeonjeongwonlim, and the results of the study were as follows; First, Based on the recitation of "Seonyu pungryu(仙遊風流)" in the "Cheongsuheon-yugo(聽水軒遺稿),", Dongchangcheon Stream and Gongampungbyeog(孔巖楓壁) were influenced by the outer gardens of the Georyeonjeongwonrim. Second, Small pavilion was built and arranged under the rock of Byeongam(Byeongpungbawi) in the management history of Geoyeonjeong Pavilion. The records show that Cheongsuheon used the Geoyeonjeong Pavilion as the original forest and even recognized Oewon, which is a scenic influence, as the Gongampungbyeog Cliff. Third, Many of the poems related to Gongam were recognized as Seunggyeong, which represents the Unmun area, and the eight scenery of Cheongdo and Unmungugok were established here as proof that Gongampungbyeog Cliff was very faithful to the traditional Seunggyeong aspect of Gongampungbyeog Cliff, and the crystalline structure of the location was implied as an external source of Geoyeonjeongwonlim. Fourth, The lower part of Dongchangcheon Stream, which stretches from Geoyeonjeongwonrim to Gongam, is filled with attractions consisting of cancerous areas such as Punghodae, Moseongam, Buangdae, Gokcheondae, Saganjeong, Hakgadae, and Hyeongjeam, which provide a clearer picture of the space and landscape of the Geyeonjeongwonrim Outer Garden. Fifth, The expression "dragging water, spilling it into the courtyard, and sending it back to the downtown of the field" of the Cheongsuheon-yugo suggests that the site of Geoyeonjeong Pavilion was originally a prevention. It is also inferred that Cheng Shu-heon also wanted to respect runners and pursue natural views like runners. Sixth, The record of planting a description of spring water and willow trees in "Geoyeonjeong Manyeong(居然亭晩影)」" and "Sanggukseol(霜菊說)」" suggests that the chrysanthemum was planted and planted, and that the chrysanthemum was used to describe the Osanggojeol(傲霜孤節), which means that he would not yield and keep his incision alone despite severe frost. Seventh, It is believed that the writing was written by Cheongsuheon in 1844 during the period of the creation of the Wonrim. The rock letters on the floor of Geoyeonjeong suggest the names of the receiving and the winning prizes. Most of the passages are based on nuclear power plants, including Muidogyo of the Zhuzi, and most of them incorporate the virtues of the Gunja and the natural views of the Eunja. In addition, the rock writing 'Gyeong(敬)' or 'Uidang(義堂)' is a substitute for special worship objects or introspection, adding to the significance and scenic properties of the Georyeon Garden Forest.

  • This research is to investigate his creative perspective to Deahak through Seoktan Lee Shin-Ui's Daehakcharok. Lee Shin-Ui is a scholar and politician in the middle of Joseon Dynasty. His ancestral home is Jeonui. The honor name is Gyeongchik and pen name is Seoktan. The posthumous name is MunJeong. His Daehakcharok was written in the process of taking basic foundation as the politic leader. It was a record that he usually wrote down things realized after reading Deahakjanggu. Seoktan clearly classified the meaning of Jang (chapter) and Gu (phrase) as the structure of Deahakjanggu, and created new realm about the method of classified study. In the preface of Deahakjanggu, he emphasized that the core of Deahak is in Gyeong (敬, respect or honor), and clarified that Deahak deals with Sim (心, mind) and Seong (性, human nature). In the interpretation of Daehakdeajeon, he thought that the core of Samgangnyeong (三綱領, three doctrines or essential principles) depended on Myeong (明, realizing), Shin (新, taking re-newness), and Ji (止, achieving) as the meaning of 'realizing, taking re-newness, and achieving', and interpreted the context of Tao (道, the way), Myeong (明, realizing), and Deuk (德, virtue) in detail. In addition, he interpreted various concepts and meaning of Deahak with Myeongmyeongdeuk (明明德, realizing human nature) and Sinmin (新民, renewing people) as relationship with Ji(知, realization), Haeng(行, practice), Che(體, main structure), and Yong (用, dealing with), and developed Neo-Confucianism deeply. In case of the main interpretation of Deahakjanggu, he analytically reviewed 50 phrases one by one throughout 10 total chapters. In case of chapter five which includes Zhuzi's the theory of Gyeokmul (格物, approaching things or persons), he interpreted it in three parts and classified Gyeokmulchiji (格物致知, approaching things or persons and then realizing their nature) about researching deeply of principle and each thing, and Mulgyeokjiji (物格知至, approaching things or persons and then realizing them) about all things. He arranged in order of 'principle- researching-result' as well. In final, chapter ten showing the core of politic thought emphasized the way of Hyeolgu (?矩, considering others' situation through his/her own experience) intensively and informed that it is the best virtue for a governor.

  • This thesis aims to research the original landscape of an area in Chirwon by comparing and interpreting the current and the former landscape of the time around 1860, in which was created. Inside the painting, MuGi-YeonDang(舞沂蓮塘), its nearby garden facilities and landscape are described. The conclusions of the research are as follows. Around the inner garden(內園) called Gukdam(菊潭), core spaces of Mugi-YeonDang were Hahwanjeong(何換亭) and Pungyongnu(風浴樓). After 1971, Chunghyosa(忠孝祠), Yeongjeonggak(影幀閣) which was built as inheritance of Giyangseowon (沂陽書院), and other buildings were added. On the opposite of Hahwanjeong, there is a designed pond inside Gukdam, in which three pieces of bizarre stones and colorful flower plants and trees reside. In the middle of the pond, there is an center island(中島), constructed with Bonghwangseok(鳳凰石) and Napduseok(衲頭石). Two different kinds of trees are settled on top of the stones, and one of them is identified as a maple. In the external scenery(外境), Jakdaesan Mountain and Cheonjusan Mountain are located at the upper part of Mugi-Yeondang, and Bibo Forest(裨補林), which does not exist anymore, was located at the lower part of it. A notable achievement in own research was to discover the Ju family's graveyard(朱氏墓群) consisted of more than 10 murals at the lower part of Mt. Jakdaesan in the outer space and the remains of 'Byeoreop(別業) Yuhoejeong(有懷亭)' at the nearby Sanjeong-ri(山亭里) area, which was the Ju family's gravesite(Seonsan, 先山). The discovered remains showed the presence of a square pond(方塘) and an island in the center of it(中島) in the form of Seokgasan(an artificial mountain made with stones), a stone monument called Mangchudae(望楸臺), etc. The Seokgasan was consisted of processed natural stones, and layers of the stones were piled up for it. On the side of the layered stones, 'Gyeongam(敬嵒)' and 'Sesim(洗心)' are engraved. Especially, Gyeongja(letter Gyeong, 敬字) is a copy of the Gyeongja Rock(敬字岩) of Sosu-Seowon(紹修書院), which is a symbolic garden language mutually used in the signboards of Pungyongnu and Musansa(武山祠), a place built to enshrine Ju, Sebung(周世鵬). Through the written names of the building found in , it can be assumed that the name of the square pond with Seokgasan was Taehwaji or Jeongwudang, and the name of the Seokgasan was Sogeumgang(小金剛) or Sobangjang(小方丈). The names correspond to the names of the Seokgasan of Gukdam, which was Yangsimdae(養心臺) and Bongnaesan(蓬萊山). By means of the corresponding names, it can be inferred that the relations between the spaces were intended. was originally created as 'a manor painting(莊園圖)', led by the 15th generation of the Ju family who moved into Chirwon-ri, Haman. The painting describes not only the back garden but also the external scenery, thus it provides important evidences for understanding Mugi-YeonDang and its nearby landscape, and is helpful to its maintenance and restoration.

The Comparison of 'Oneness between Heaven and Man(天人合一)' thoughts between Zhoudunyi(周敦頤) and Kwonkun(權近) - Focusing on "Taijirushuo (太極圖說)" and "Ip-Hak-Do-Seol(入學圖說)" (주돈이와 권근의 천인합일사상 비교 - 『태극도설』과 『입학도설』을 중심으로 -)

  • This article is an attempt to identify the difference between "Oneness between Heaven and Man(天人合一)" thought proposed by Zhoudunyi(周敦?) in 'Taijirushuo(太極圖說)' and "Cheon-In-Sim-Seong-Haap-Il(A diagram about Unifying Heaven, Human, and Mind-and-Heart)(天人心性合一)" thought presented by Kwonkun(權近) in 'Ip-Hak-Do-Seol(入學圖說)'. Oneness between Heaven and Man thought, which have developed into practical ideas centered on self-cultivation theory, have a philosophical depth and logical system by Zhoudunyi(周敦?) with 'Taijirushuo(太極圖說)' in order to summarize the metaphysical cosmology and the treatise of human nature in Dynasty Song. Zhoudunyi established the concept of Wuji(無極) corresponding to Heaven(天), and suggested unified cosmology of 'Wuji(無極)-Taiji(太極)-Yin and Yang(陰 陽)-Five elements(五行)-Human(人間)-Everything(萬物)'. His cosmology is the perception that heaven, the creator of all things, is the relationship of unity, which is connected by man as the creature and the Order(命)and Nature(性). Thus, when people restores one's nature and realized that it is a mandate from Heaven, he said that heavenly unity can be realized and become a Saint(聖人). The idea of Zhoudunyi(周敦?) comes to Zhu Xi(朱熹) about 120 years later and it is concluded to be converged the Neo-Confucianism with Lichi theory. Accordingly, Zhoudunyi(周敦?) is evaluated as the master of the Neo-Confucianism to posterity. KwonKun suggested the idea of "Cheon-In-Sim-Seong-Haap-Il(A diagram about Unifying Heaven, Human, and Mind-and-Heart)(天人心性合一)" in 'Ip-Hak-Do-Seol(入學圖說)' at the end of Goryeo Dynasty. KwonKun's "Cheon-In-Sim-Seong-Haap-Il" thought is logically coherent by adding an element of the doctrines of Chu-tzu to his teacher Yi Saek's "Chun-In-Mu-Gan" and arranging that the functions of my mind and Li(理) are all together. Whereas Zhuodunyi is concerned with the creation principle of the universe and all things, KwonKun mainly cares about Heaven(天), Human(人), and Heart (心), and Nature(性) in the view of psychology. In addition, he suggested that "Cheon-In-Sim-Seong-Haap-Il" can be achieved by self-cultivation centered of Gyeong-thought(敬思想). The idea of KwonKun has become a stepping stone to the development of the doctrines of Chu-tzu based on psychology. His ideas came to Yi Hwang about 150 year later, and are integrated into four clue-seven emotion (Sadan Chiljung四端七情) thesis and Gyeong-thought(敬思想). However, unlike the Zhoudunyi, KwonKun is not properly evaluated despite his academic accomplishments.

Academic Enrichment beginning from the Great Learning(大學, Dae Hak, or Da Xue in Chinese) toward the Essentials of the Studies of the Sages(聖學輯要, Seong Hak Jibyo) in the respect of Cultivating Oneself(修己, sugi) (수기(修己)의 측면에서 본 『대학(大學)』에서 『성학집요(聖學輯要)』로의 학문적 심화)

  • This paper was a quest of pattern of holding "Dae Hak - the Great Learning" during Joseon Period having investigated the characteristics of the Essentials of the Studies of the Sages(聖學輯要, Seong Hak Jibyo) that was compiled by Lee I was a reinterpretation of the Great Learning, and also academic enrichment. During the period of Joseon Dynasty, the Great Learning had held the most important position as core scripture in the intellectual society that pursued Seong Hak(聖學, sage learning). Throughout the Joseon Period, the Great Learning was the essential text for the Emperorship Learning(帝王學, Jewang Hak) as well as Seong Hak, and it can also be said that Seong Hak Jibyo compiled by Yulgok - the courtesy name of Lee I, was the comprehensive collections thereof. While compiling Seong Hak Jibyo, Yulgok presented a model of Seong Hak of Joseon, which was based on "the Great Learning". Yul Gok organized the system of "Seong Hak Jibyo" largely in five parts, and properly arranged the Three Cardinal Principles(三綱領, samgangryeong) and Eight Articles or Steps(八條目, paljomok) therein. Particularly, in the Chapter Two, "Cultivating Oneself(修己, sugi)", Yulgok deal with 'being able to manifest one's bright virtue'(明明德, myeong myeong deok) among the Three Cardinal Principles as the core curriculum, meanwhile, Yulgok also covered "Investigation of things, gyeongmul(格物)," "Extension of knowledge, chiji(致知)," "Sincerity of the will, Seongui(誠意)," "Rectification of the mind, Jeongshim(正心)," "Cultivation of the personal life, susin(修身)," among Paljomok(eight steps) as the ultimate purpose of 'Stopping in perfect goodness'(止於至善, jieojiseon) These well preserve the principal system of Confucianism where "Cultivating oneself and regulating others (修己治人, sugichiin)" are core value, and his instructions as such also back up academic validity logically by presenting specific guidelines for practice according to each domain. Reinterpretation of "The Great Learning" by Yulgok in Seong Hak Jibyo is an arena to investigate the characteristics of Confucianism in Joseon Period, which was different from that of China, furthermore, such guidelines might take a role as criteria to understand the characteristics of humans and learning possessed by Korean people.

A Study on Heart-Mind of Daesoon Thought from the Perspective of Neo-Confucianism: Focused on Numinous Emptiness, Wise-awakening, and Divine Beings (주자학으로 본 대순사상의 마음에 관한 연구 - 허령, 지각, 신명을 중심으로 -)

  • This study aims to look into Daesoon Thought from the perspective of Neo-Confucianism. Numinous emptiness (虛靈), wise-awakening (知覺), and divine beings (神明) in the Scripture of the Black Tortoise (Hyeonmu-gyeong) are often mentioned as characteristics of the mind in Neo-Confucianism. Accordingly, this research take up the 'Che-Yong (substance, 體 and function, 用)' of mind by classifying numinous emptiness as Origin-Substance (本體), wise-awaking as function, and divine beings as subjects. Numinous emptiness enables an individual to have been born with Li (理) of Taegeuk (太極), which is a mandate from Heaven and the nature of humanity; whereas one embodies spirit and brightness mind based on Origin-Substance. This numinous emptiness of mind is precisely the mind-spirit. Wise-awakening is a function of mind, which actually awakens numinous emptiness (理) and objects (氣). The mind which realizes the Li of Taegeuk as numinous emptiness is conscientiousness and can be taken as a Dao-Mind. The mind which desires objects refers to the Human Mind or a selfish motive. Such propensity in terms of wise-awakening determines the state of mind. One should reach the state of a quiet mind by wisely awakening through the scripture. Divine beings correspond to metaphysical Origin-Substance and physical objects respectively. In addition, they comprehend all and preside over wise-awakening as subjects. The subject recognizes wise-awakening and responds to it. Mind is a path traveled upon by divine beings as they enter and exit. In this regard, the human mind refers to the organ used by immanent deities, which accumulates physical senses, innermost mental processes, and awakened activities. Furthermore, Transcendental deities also come in and out through mental correspondence, leading to changes in one's physical constitution or personality. This paper focuses on the mind perceived in Daesoon Thought as follows: first, besides the existing spiritual perspective, the research takes a view on surveying numinous emptiness, wise-awakening, and divine beings in Neo-Confucianism. Secondly, the Che-Yong of mind is closely looked into by means of innate numinous emptiness as Che and wise-awakening as Yong. Lastly, the essence, energy, and divinity as well as spiritual soul and physical soul are mentioned according to the concept of an immanent deity. The paper also clarifies the fact that divine beings preside over the mind as subjects.

A Study on Yulgok School Scholars' Theory to Study "Daehak(大學, Great Learning)"-Focusing on Horon(湖論) and Nakron(洛論) Scholars' Opinions of Bunyeom(浮念) and Pyeonnyeom(偏念) (율곡학파 학자들의 『대학』 공부론 연구- 부념(浮念)과 편념(偏念)에 관한 호론과 낙론 학자들의 견해를 중심으로 -)

  • In this thesis, based on Yulgok's theory to study "Daehak", it was examined how scholars of Horn and Nakron developed the theory to study "Daehak" regarding Bunyeom and Pyeonnyeom in the context of the history of ideas. The scholars of Horon and Nakron developed Yulgok's theory to study "Daehak" arguing that one could fully recover a saint's mind only after studying Seongeui(誠意, sincerity) to get rid of Aknyeom(惡念, an evil intention), Jeongsim(正心, an upright heart) to control Bunyeom, and Susin(修身, moral training) to control study and Pyeonnyeom. Yet, as scholars of Nakron criticized Horon scholars' argument considering the study of Jeongsim to control Bunyeom as Jeongsi(靜時, calm time), the controversy over the theory to study "Daehak" developed. The scholars of Horon generally insisted that because the method of Seongchal(省察, introspection) suggested in "Jeongsimjang(正心章, Chapter of Upright Heart)" of "Daehak" was not going into Dongsi(動時, dynamic time) and fathoming with Saryeo(思慮, consideration), but releasing it at the very moment of catching the indication of four troubles relevant to Bunyeom, the study on Jeongsim in "Daehak" should be the study of Jeongsi(靜時, calm time) for Jonyang(存養, developing good nature) of the main part of mind. On the other hand, the scholars of Nakron mostly contended that because Sim(心, mind) discussed in "Jeongsimjang" of "Daehak" referred to the whole mind and was not limited to Mibalsim(未發心, mind not manifested yet) of Jeongsi(靜時, calm time), the study on Jeongsim should include Dongjeong(動靜, movements). Yulgok once commented on Lee Yeon-pyeong(李延平)'s study on Mi-bal-che-in(未發體 認) in the same context of the study methods of release at the very moment of light reflection(輕輕照管·輕輕放退). In this respect, study on Jeongsim to control Bunyeom can be separated and belong to the study on Mibal of Jeongsi(靜時, calm time) as the scholars of Horon did. On the other hand, from the aspect that regarding the study on Jeongsim, Yulgok discussed both Jonyang(存養, developing good nature) and Seongchal(省察, introspection) with Mibal(未發, not manifested) and Yibal(已發, already manifested) together, it seems to have no problem to think of Jeongsim as the study including Dongjeong(動靜, movements). There were no different opinions between the scholars of Horon and those of Nakron regarding that there was study of Jeongsi(靜時, calm time) in "Daehak", too. However, while the scholars of Horon usually understood the study of Jeongsim in "Daehak" itself as the study of Mibal in "Jungyong", some scholars of Nakron thought that even though the study of Jeongsim of "Daehak" corresponded to Dongsi(動時, dynamic time), it included the study on Mibal because of the logic of Che-yong-il-won(體用一源). It can be said that the discussion over the study of Jeongsim to control Bunyeom and the study of Susin to control Pyeonnyeom were not limited to the proposal of the methodology to just control Bunyeom and Pyeonnyeom, but developed into the understanding of "Daehak" and "Jungyong" as one system of study.
