摘要:AF TERthe optimism which followed the falling of the Berlin Wall, onehas found out that the alternative to Cold War wasn't the Global Peace.Regional con.icts have grown stronger, becoming more intense than ever. Atseveral levels, some taken-for-granted evidences were shaken by new social,cultural, political and technological phenomena.Risk, contingence, and entropy became major categories of contemporarytheoretical approaches. The post-modern society appears now to contempo-rary thought as a new world shaped by social and cultural fragmentation, andthe eruption of new identities. The emergence of a novel public sphere con-cerned, mainly, with emergent social and political rights of minorities; andthe constant .ow of people, either immigrants or refugees crossing culturaland geographic spaces, brought to light new and old identities, leading thoseancient and secure borders to collapse. Some con.uent phenomena such as en-vironmental problems, contemporary hazards associated with nuclear power,chemical pollution, terrorism, changes on cultural attitudes, the "women's lib"and their subsequent arrival to labour market, the crisis of the old traditionalmediation apparatus (Church, Family, Tradition), the decadence of ideologies,emerge as main features of a society where everything that was solid meltedon air (Adam, Beck, e van Loom 2000: pp 6-7). Increasing re.exivity in faceof answers once taken-for-granted challenged by those enormous changes, andanxiety in face of a changing world makes that concern with security and riskbecome a major problem of our societies. Insecurity is thus an existential con-text: we don't know anymore how to go on the basis of tradition. The implicitvalidity claims of taken-for-granted values and traditions become problematicand potentially questioned (Adam, Beck e van Loom, 2000:37)-
