It gives an intimate view inside the main character.
This passage gives an intimate view inside the main character; it gives us his intimate tastes for listening to other people speaking. He describes very well these thoughts as something he never shares with anyone, he mentions these thoughts only to himself like inner wisdom, like holding a prize, and he knows it is a prize that nobody or very few possess. This is why he feels proud of himself, because he is one of the very few who can really listen, for him it is listening a skill that overpowers humanity, a humanity so timeless to give importance to what really empowers it. He considers this skill, this art of listening so important that he never sees his own topics of conversation as worthy of sharing and when he speaks it is because he feels that what he is listening lacks variety and decides to intervene so that the speaker can find different words to express his or her ideas.
