Greening of America (book by Charles Reich): “There is a revolution coming. It will not be like revolutions of the past. It will not require violence to succeed, and it cannot be successfully resisted by violence. It promises a higher reason, a more human community, and a liberated individual. Its ultimate creation will be a renewed relationship to society, to nature, and to the land.”
