So why water? Things present themselves most intensely right at the edge of their absence. This is the intrinsic drama of the urban waterfront — so much complexity right up against what reads to us as vast emptiness. Touching a large body of water is a contact-with-the-infinite that intensifies my sensation of the richness of the finite. So, after touching the water, I turn back — to the city or landscape that was behind me — and can how feel (not just know) that I’m seeing something that is vulnerable, contingent, even doomed sooner or later, and therefore real.
