Walking itself is the intentional act closest to the unwilled rhythms of the body, to breathing and the beating of the heart. It strikes a delicate balance between working and idling, being and doing. It is a bodily labor that produces nothing but thoughts, experiences, arrivals.

Language is like a road, it cannot be perceived all at once because it unfolds in time, whether heard or read. This narrative or temporal element has made writing and walking resemble each other.

There are those who receive as birthright an adequate or at least unquestioned sense of self and those who set out to reinvent themselves, for survival or for satisfaction, and travel far. Some people inherit values and practices as a house they inhabit; some of us have to burn down that house, find our own ground, build from scratch, even as a psychological metamorphosis.

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.

Time itself is our tragedy and most of us are fighting some kind of war against it.

For millions of years, this world has been a great gift to nearly everything living on it, a planet whose atmosphere, temperature, air, water, seasons, and weather were precisely calibrated to allow us - the big us, including forests and oceans, species large and small - to flourish.

How will you go about finding that thing the nature of which is totally unknown to you?
