Space--as landscape, terrain, spectacle, experience--has vanished.

I grew up with landscape as a recourse, with the possibility of exiting the horizontal realm of social relations for a vertical alignment with earth and sky, matter and spirit. Vast open spaces speak best to this craving, the spaces I myself first found in the desert and then in the western grasslands.

Violence always seems to me the worst form of tyranny. It deprives people of their rights, including the right to live.

Everywhere people are at work to build a better world in which we - and some of the beauty of this world - will be guaranteed to survive. Everywhere they are at war with the forces threatening us and the planet.

A restlessness has seized hold of many of us, a sense that we should be doing something else, no matter what we are doing, or doing at least two things at once, or going to check some other medium. It's an anxiety about keeping up, about not being left out or getting behind.

It is the job of artists to open doors and invite in prophesies, the unknown, the unfamiliar; it’s where their work comes from, although its arrival signals the beginning of the long disciplined process of making it their own. Scientists too, as J. Robert Oppenheimer once remarked, ‘live always at the ‘edge of mystery’­—the boundary of the unknown.’ But they transform the unknown into the known, haul it in like fishermen; artists get you out into that dark sea.

In great cities, spaces as well as places are designed and built: walking, witnessing, being in public, are as much part of the design and purpose as is being inside to eat, sleep, make shoes or love or music. The word citizen has to do with cities, and the ideal city is organized around citizenship -- around participation in public life.
