We are moving into a world of unaccountable and secretive corporations that manage all our communications and work hand in hand with governments to make us visible to them. Our privacy is being strip-mined and hoarded.

The magic of the street is the mingling of the errand and the epiphany.

I feel like we're in a truly revolutionary period, not just in terms of practical activities to overthrow regimes in the Middle East or Occupy but also in terms of radical redefinitions. I feel like workers are a big part of it, but there's so much more going on.

A labyrinth is a symbolic journey . . . but it is a map we can really walk on, blurring the difference between map and world.

There is so much information that our ability to focus on any piece of it is interrupted by other information, so that we bathe in information but hardly absorb or analyse it. Data are interrupted by other data before we've thought about the first round, and contemplating three streams of data at once may be a way to think about none of them.

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

Books are solitudes in which we meet.
