The correct answer is “Being content does not always lead to growth” and “Learning about the past can bring wisdom.”
Indeed, the participant first person narrator begins his recollection by stating how happy his knowledge of the “Old Books” made him back then. However, he immediately states that he still had “questions he could not answer”. Then he uses a very interesting metaphor for knowledge: “fire”. It is interesting because fire has both a positive and a negative property, it gives both light and warmth but also it burns and consumes. Thus, knowledge is positive because it helps a person understand himself and his world, to “light” the way and it also improves life as the inventorial description of the technological and educational advances show (the spin wool wheel, the Old books). However, fire also consumes wood, so to keep it burning more wood is required just like knowledge shows a person that although he knows many things there are a lot more things the he does not know (lack of knowledge) and that new knowledge will light the way of humanity and make it grow. The fact that he decides to leave his family after such reflection shows that he is leaving to get more wood for his inner, sacred fire, to get more knowledge for his mind.
