여헌(旅軒) 장현광(張顯光)(1554-1637)이다. 그는 한국 16-17세기의 저명한 사상가이다. 그의 사상은 퇴계와 율곡의 학설을 흡수하고 계승하였을 뿐 아니라 자신의 독창성을 드러내고 있다. 그는 퇴계와 율곡의 이기설을 극복하고 종합하여 자신의 독창적인 "이기경위설(理氣經緯說)"을 제기하였고, 그로 인해 한국 성리학의 특색을 갖춘 인물이 되었다. 그는 경위(經緯)의 구조(構造)로 이기(理氣)의 관계를 관찰하고 분석하였으며, "이(理)(경(經))"를 불변의 표준으로 삼고 "기(氣)(위(緯))"를 가변적인 작용(作用)으로 삼았다. 이를 통해 성리학의 이기(理氣) 관계를 새롭게 해석하였다. 세계 구성을 이기(理氣)의 측면에서 현상론적인 측면에서 본다면 이기일물(理氣一物), 이기경위(理氣經緯)는 이기일원론(理氣一元論)으로 해석될 수 있다. 이기경위설(理氣經緯說)의 전제(前提)는 분합론(分合論)으로 이어진다고 본 다. 합(선(先))-분(금(今))-합(후(後))은 시간적 순서, 형이상하적 구분을 의미한다고도 볼 수 있을 것이다.

This paper examines Jang Hyeongwang's cultural awareness and the way of practice by focusing on his spirit of humanities in relation to the understanding of territory and bibliographic materials. In fact, this starts from conflicting evaluations on Jang Hyeongwang's way of learning in the field of Korean history. Jang Hyeongwang emphasizes realization of humanity, which is considered as basic framework of culture. He claims the indivisibility of Dao(道) and culture(mun文) by arguing that almighty principle of Dao manifests itself through phenomena of culture. In other words, Dao is the root of culture and, at the same time, culture is the necessary element of making Dao valuable. Furthermore, he insists that realization of human culture is the gist of manifesting the pattern of nature. In this vein, the roles of human beings are so important in creating humanistic civilization. He considers all kinds of human affairs as the contents of humanistic culture, which are contained in six classics. Especially, He says that the moral is reality of human culture and that literature is a literal expression of humanistic spirit. Thus, he criticizes that there are literatures without moral practices. He pays a special attention to his indigenous culture. He links the cultural understanding of geography, which is the foundation of realizing humanistic spirit, to awareness of Korean territory and grasps the territory in the light of topography of geographic power. Thus, he defines it as "Central Field" which bears comparison with China (middle kingdom). With the positive understanding of his country, he insisted that Korean indigenous culture and custom are as much advanced as China and was so proud of the moral characters and norms that Korean people had formed so far. Moreover, Jang truly exhibited affection to Korean literature, which had formed through Korean history. Kim Hyu, one of his students, activates Jang's will to preservation of Korean culture. Over twenty years, Kim completed Collected Record of Korean Literatures(haedong munhon ch'ongnok 海東文獻總錄). Actually, he started the preparatory works for compiling them. We should keep in mind that this compilation was completed following Japanese Invasion of Korea in 1592. It means that he has cultural awareness of preserving Korean literal heritages. Hence, it can be evaluated as the results of the enhancement of national studies. We have seen that He truly highlights realization of humanistic spirit by insisting the practices of moral values. In fact, his mind is linked to genuine affection to Korean territory, culture and literatures. Such affection can be paraphrased as moral awareness of humanity and its practices. In conclusion, his humanistic spirit should be understood as strong belief on universality of human morality. His cultural awareness of homeland and the will to practices should be considered as cultural pride of Korean intellectual traditions rather than following Chinese culture blindly.

This thesis is for clarifying a few aspects of 'Kyung(敬)' ideology and figures appearing in Yeheon(旅軒)'s poem. This ideology and figures is a kind of a imaginative thing that a poet designed. This feature is a very important subject of Yeheon(旅軒)'s poem world, so that we are going to make it clear. First, we focused his aspirations of virtual uncontaminated areas and found out his big store of life wisdom and knowledge. The second is we thought about a displaying a emphasis of proud spirit[氣像] in his own poem world, and we found that he saw things from an unworldly point of view. Finally we talked about several features of Yeheon(旅軒)'s poem world. Now we have to compare Yeheon(旅軒)'s poem and any other Dohakpa(道學派) poets for example Toegye(退溪), Hwejae(晦齋) etc. And we must clarify the whole poem world of Dohakpa(道學派). In the end, I'm so sure that we will get a prospect of their literature.

Jang Hyeon-gwang(張顯光, 1554-1637), whose pseudonym or courtesy name is 'Yeoheon(旅軒)', had made a thorough study on the intrinsic nature of Neo-Confucianism in a more sincere fashion, when comparing him with other Neo-Confucianists in Joseon period. Also he was a renowned scholar who expanded its philosophical system in-depth. Yeoheon thereby had strengthened his philosophical system accordant with the Great Learning(大學) and Doctrine of the Mean(中庸), which are the fundamental systems of Neo-Confucianistic education. Based on such considerations, Yeoheon's thought on education can be illuminated from three different perspectives. First, Yeoheon deepened his a theory of good governance by a virtuous ruler(聖人君主論, pronounced, 'Seongingunjuron') as the standard of education. Essentially, his theory pursues Refraining from desire, and preserving the laws of nature(存天理?人欲, pronounced, 'Joncheolliarinnyok'), and put emphasis on ethical awakening, and the governance through a virtue of moral excellence. Second, Yeoheon stressed the learning theories related to 'sincerity' or true heart(誠) and 'piety' or 'respect'(敬)) as the form of education(誠敬, pronounced, 'Seonggyeong'). Also he expounded that people needs "to establish a ground of Respect and Sincerity in their mind." He recognized the differences between the two virtues, meanwhile, however, he understood it as in an identical context. Third, Yeoheon advocated harmony between separation and integration(分合, pronounced, 'Bunhap') as a method for education. Through his unique 'Discourse on Longitude and Latitude', dubbed, 'Li-Gi Gyeongwiseol (理氣經緯說) in which the principle(Li, 理) is equal to the intrinsic energy or material force(Gi, 氣), he maintained his view on the Doctrine of the Mean, in that he was not inclined to either sides according to the logic of Change(易, pronounced 'Yeok'). When reviewing Yeoheon's contemplation in education in the meaning of modern education, he laid the standards for education on the establishment of morality, and he also provides us with an idea which induces us to look through the form and method for education from the perspective of Doctrine of the Mean. In short, Yeoheon's view on education embodies wisdom of traditional Neo-Confucianistic Education having consistency, and it provides for an implication of the review of the importance of the balance in relation to methodological bias toward confusion in the standards for modern education, and unsystematic contents therein.

In this paper, I focused on analyzing Yeoheon Chang Hyeon-gwang's literary theory and his prose in the genealogy of Confucian scholars in Chosun. Through this study, I would like to examine the trend of concentrating on 16th century when we treat the literary tendency of Confucian scholars. With this goal, I tried to seek the direction which was pursued by Confucian scholars who lived during the 17th century. Yeoheon tried to construct the spirit of humanities cosmically as an aim of his life, study, and literature. And he had a new understanding of human independence by suffering from Japanese invasion in the late of 16th century. He insisted that only human can realize the spirit of humanities on a cosmic base. He also thought that the morality(道) could be settled only by literature(文). We may interpret this concept as a progressive idea about literature comparing to the former Confucian scholars. On the other hands, Yeoheon tried to accept the literary theory of former scholars such like Park Young, Cho Sik, and Seong Woon who embraced Taoism. Yet he erased the color of Taoism in the field of topic, and he also tried to keep his distance from them in the field of literary form. This concept actually came from Lee Hwang's opinion, while Yeoheon tried to rouse scholar's independence. Through above, we may realize that the Confucian scholars of 17th century were not just imitators of 16th century. They tried to examine the former study and also tried to renew the theory.

Kim, Kyung Jang(1597~1653) as a disciple of Jang Hyun Gwang was very famous for his virtuous conduct. But his collection of works has been published recently. There has never been any studies about his thoughts, learning and life. Therefore this study has a target to arrange the process of his life and events, and to introduce outlines of his learning. The items of this study will be as follows: The first category will be his lineage, his life, and writings. The second category will be his learning. This category has two lower categories. The first will be focused on his intention to morally accomplished self by the method of self cultivation and practise of Confucian proprieties. The second will be focused on his learning of the Change and of the Confucian proprieties. And giving attention to his 6 diagrams that have symbolized principles of the Change, this paper tries to compare these to the other scholars ones and so will explane the features of his diagrams. The most important thing in this paper is to define his learning as so called in the rhetoric of Confucianism Wi-gi-ji-hak(爲己之學), which means self organization of one's moral personality by the method of self cultivation and to distinguish the steps of his learning developed. This method has never been applied, but this is expected to become a effective method for explanation of the truth of the Confucian scholar's world of learning.
