Anywhere - and, it follows, nowhere - can be a place. As long as we are there, to think and talk, to listen and respond.

What sounds there is not the divine music of celestial spheres, as the ancient Greek mathematicians believed, but the sound of one human after another issuing the daily plea: to be heard, to be understood, to be accommodated.
