At least in my neighborhood, we didn’t shoot hoops or play Scrabble. We didn’t play cards to pass the time, we didn’t watch TV, we didn’t shop, we most certainly did not go to the mall. The first organized activity that I saw in New York, that same day, was singing. People sang. People sang around fire houses, people sang “We Shall Overcome”. Lots of people sang America the Beautiful. The first organized public event that I remember was the Brahms Requiem, later that week, at Lincoln Center, with the New York Philharmonic. The first organized public expression of grief, our first communal response to that historic event, was a concert. That was the beginning of a sense that life might go on. The US Military secured the airspace, but recovery was led by the arts, and by music in particular, that very night.
He talks extensively about Messiaen's Quartet for the End of Time and other artworks created in concentration camps, and uses these experiences to argue that the arts are as essential to human life as eating and breathing. He continues to charge the Boston freshmen with these words:
Frankly, ladies and gentlemen, I expect you not only to master music; I expect you to save the planet. If there is a future wave of wellness on this planet, of harmony, of peace, of an end to war, of mutual understanding, of equality, of fairness, I don’t expect it will come from a government, a military force or a corporation....I expect it will come from the artists, because that’s what we do.
