Jolsoojae lived in the middle of the 17thcentury in the midst of social irregularities, contradictions and vices caused by severe political strife and controversy. He came to realize through the father of the study of history, Yujogyum, that history is a mirror of the present, and he came to develop a perspective that recognized that reading about history is a scholarly pursuit and that this knowledge must be outwardly expressed in real life. Based on this, in the cultural backdrop of decadence and inconsistency, realizing that only the way for him to have a mutual understanding with the society around him was through his studies and with the mind frame of attempting to find satisfaction from his own misfortune and filtering his resentment through history and great persons of late—this was the background behind writing “Doksa Yoogam.” Thus, through criticism of the political authorities and the social mindset of people of his time, he took aim at the social conditions of his time. He viewed the great people of late and their lives, and expressed his desire to participate in social life, and the hopelessness that he felt from the gap with reality, he resolved by reflecting on nature. The hopelessness that he felt from the conditions of his time and the resentment, the book shows that he tried to overcome by scholarly achievement. Thus, “Doksa Yoogam” reflects on the times through history, suggests a solution to the problems of reality, and reflects well the thinking of Jolsoojae that there is scholastic value within history.
