The "same high school or hometown or church" provides social relations on which the "study circles" are later built. The study circles themselves constitute a form of social capital-a cellular form of organization that appears especially valuable for facilitating opposition in any political system intolerant of dissent. Even where political dissent is tolerated, certain activities are not, whether the activities are politically motivated terrorism or simple crime. The organization that makes possible these activities is an especially potent form of social capital.
