Walkers are 'practitioners of the city,' for the city is made to be walked.

Just as language limits what can be said, architecture limits where one can walk, but the walker invents other ways to go.

There's enough food in this world. There's enough housing in this world. There's enough shelter in this world. There's enough clothing in this world. There's enough teachers, there's enough universities for everybody's needs to be met, and the reasons they aren't is not because of lack of resources. It's because of distribution, and that's the politics of hate, which is why this is a movement against that. It's a politics of love.
