Here is a quote from Buenaventura Durruti, the anarchist resistance leader from the Spanish civil war. It is not hard to see what it is making it rounds through the Occupy blogosphere (perhaps via the Indignados?). I am quoting it to show a trend within Occupy to move from camping to squatting and the uncharted world of DIY-architecture beyond that.
"We have always lived in slums and holes in the wall. We will know how to accommodate ourselves for a while. For you must not forget that we can also build. It is we who built these palaces and cities, here in Spain and America and everywhere. We, the workers. We can build others to take their place. And better ones. We are not in the least afraid of ruins. We are going to inherit the earth; there is not the slightest doubt about that. The bourgeoisie might blast and ruin its own world before it leaves the stage of history. We carry a new world here, in our hearts. That world is growing in this minute." - Buenaventura Durruti
