A lone walker is both present and detached, more than an audience but less than a participant. Walking assuages or legitimizes this alienation.

The poor have often been subversive just because they don't always believe their own depiction as brutes and loafers and leeches, and new economy is making lots more poor or recognize their fellowship with the insecurity of the poor, the portion of the population for whom the system does not work.

The art is not one of forgetting but letting go. And when everything else is gone, you can be rich in loss.

Think of civil society and the state as joined in a marriage of necessity. You already know who the wife is, the one who is supposed to love, cherish and obey: that's civil society. Think of the state as the domineering husband who expects to have a monopoly on power, on violence, on planning and policymaking.

Cities have always offered anonymity, variety, and conjunction, qualities best basked in by walking: one does not have to go into the bakery or the fortune-teller's, only to know that one might. A city always contains more than any inhabitant can know, and a great city always makes the unknown and the possible spurs to the imagination.

Perhaps it’s that you can’t go back in time, but you can return to the scenes of a love, of a crime, of happiness, and of a fatal decision; the places are what remain, are what you can possess, are what is immortal. They become the tangible landscape of memory, the places that made you, and in some way you too become them. They are what you can possess and in the end what possesses you.

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.
