" Bats are flooding out from the hundreds of caves that perforate these mountainsides. I watch them plunge into the mists without any hesitation, trusting in the echoes and silences in which they fly. Are all of us the same, I wonder, navigating our lives by interpreting the silences between words spoken, analyzing the returning echoes of our memory in order to chart the terrain, in order to make sense of the world around us? "
