This study is about the origin of Toigye's SaDanChilJeongRiGiHoBalRon (四端七情理氣互發論: theory of humanity and the relation between humanity and heaven's principle). In this study, I looked into the influences of Toigye's elders on such theory of Toigye. In this process, I introduced SimHakJangGuJipJuDaeJeon (心學章句集註大全) I obtained recently as a main material. This book was written by an uncelebrated scholar born in 60 years before Toigye. It showed "SaDanRiBalYiGiSuJi ChilJeongGiBalRiSeungJi (四端理發而氣隨之 七情氣發而理乘之)", which was as same as Toigye's study logic. Regarding the fact that such two logics were same, I traced the transferring path of such logic weighing the possibility of transferring such book or HoBalRon shown in such book while not completely neglecting an accidental coincidence. I also induced that the pro-Toigye-era also had the academic circumstance under which RiGiHoBalRon could be born even supposing an accidental coincidence. In addition, I also emphasized that such book was positioned to pioneer Toigye's neo-Confucianism in various aspects.
