Final answer:
Sister Sara did not argue against the mistaken belief that evil was good, simply smiling instead. This teaches a lesson about choosing when it is wise to correct misunderstandings, as some may be too entrenched in their limited perspectives to see clearly, compared to a 'frog in a well'.
Step-by-step explanation:
In the context provided, Sister Sara exhibits a tranquil and wise response by simply smiling sweetly and choosing not to engage in a futile argument with someone who has mistaken evil for the good. This scenario underlines the importance of perception and understanding. The reference to someone no better than a 'frog in a well' suggests limited perspective or ignorance. Similarly, in the LibreTexts quote, the mention of a person making a mistake and needing education to see the error resonates with the idea that misconceptions should be corrected through enlightenment and knowledge.
Agreeing or disagreeing with the need for education in the face of error depends on one's belief in the potential for people to learn and grow. If one believes that individuals can change and develop a better understanding, then education is imperative when mistakes are made. However, if one believes that certain misconceptions are ingrained and unalterable, they may argue against the notion.
