Abstract
Objectives : This paper aims to suggest alternative interpretations to previous ones of 'Daedong-eo-Hyeobui(大同於協義)' and 'Gakrip-eo-Cheonri(各立於擅利)' in the chapter 'Theories on Nature and Conduct(性命論)' in Donguisusebowon(東醫壽世保元) which have been found to be inadequate. Methods : Previous interpretations were thoroughly examined, then evaluated based on the narrative form and logical probability of the Donguisusebowon(東醫壽世保元). Afterwards, correct interpretations of the contents were suggested based on the context of the chapter 'Theories on Nature and Conduct(性命論).' Results & Conclusions : Of 'Daedong-eo-Hyeobui(大同於協義)', Daedong(大同) should be interpreted as 'to gather largely' instead of 'all the same.' Hyeobui(協義) should be interpreted as 'to submit willingly' and not 'to cooperate to Ui(義).' In the case of 'Gakrip-eo-Cheonri(各立於 擅利)', Gakrip(各立) means for people of same minds to rise against evil individually while Cheonri(擅利) refers to the evil of coveting for gains individually. There are other cases where existing interpretations have been erroneous other than the suggested examples, which prompts thorough re-evaluation of the text.
