Abstract
This paper considers the problem involving ideological issues in the trial of Marguerite Porete and her book Mirouer des Simples Ames. She was burned at the stake in Paris in 1310. It is noted that she was given this sentence after 15 articles from her book were condemned as heresy; however, only three are currently known. That is, the concepts of virtue, nature, and "intent upon God" are held in question in their respective articles. The problem of the concept of virtue is concerned with the understanding about the reversal of a mentoring relationship between the Virtue and the Soul over "licentia," and the concept concerning custom. Also, the concept of nature should be viewed from the perspective of "body" and "necessity." Thus it has been shown that those concepts are not connected with moral indulgence. Lastly, the concept of "intent upon God" is considered in the context of the concepts of "consolation" and "gifts," and the meaning of being "wholly intent upon God." Porete claims that the annihilated soul should not care for consolation and gifts, because she is wholly intent upon God. Poret's own understanding concerning those concepts will be demonstrated through the above examinations.
