This adherence to a static cultural ideal has a surprising and presumably unintended consequence: not only does it ground certain permissible forms of debate but it also permits and perhaps even encourages the day-to-day subversion of norms. This comes about because the very rigidity of outward forms provides some actors with a mask with which to conceal a variety of messages, just as a strict morality may sometimes enable--through the mastery of its codes--remarkable freedom of individual action. This is why official ideologies generally deny semantic lability: acknowledging that lability would lead to the realization (p.22) that official meanings were themselves unstable. 引自 Chapter One
