Quotes that stood out for me:
"He [the conductor] depends on his power for his ability to make other people powerful."
"My job is to awaken possibility in other people."
"Who am I being that my children's eyes are not shining?"
These speak to my passion as a teacher. And I hope (or maybe would like) as a person.
The context was how some believe classical music is only for a few, and maybe if we work hard a few more could like it. The speaker argued instead that maybe classical music was for all, why not pursue a goal to help all people learn to recognize their love for mathematical activity.
This is how I certainly prefer to think of mathematics and answer why teach math. I was lucky to study with a professor at Univ. of Georgia whose dissertation and basic research/theory building program was to ask this question: Why teach Math? One of my last student-research activities while at UGA was to interview him and another well-known equity educator in mathematics. I asked him his question, what he calls the justification question, one last time (he retired a few months after the interview). His answer: that mathematics seems to be “this interesting phenomena that has arisen among human beings, and thus worthy of study because it’s such an important part of human life, historically.”
