Here's another one:
"Abstraction is the enemy wherever it is found. The abstractions of sustainability can ruin the world just as surely as the abstractions of industrial economics. Local life may be as much endangered by those who would 'save the planet' as by those who would 'conquer the world'. for 'saving the planet' calls for abstract purposes and central powers that cannot know - and thus will destroy - the integrity of local nature and local community."
(Both recent quotes taken from his collection of essays 'Sex, Economy, Freedom and Community'. Highly recommended.)
