The present thesis examines child aggressiveness in contemporary society. Starting with Winnicott s conceptualization of aggression, it investigates a specific concept, the anti-social tendencies, and how it can be useful in our understanding about the children aggressiveness. This thesis investigates also some contextual aspects of contemporary society responsible for today s increase in antisocial behavior. Decline of parental roles and childhood eclipse are signed as some of these aspects. It is assumed that children s anti-social behaviors constitute survival strategies in a world with moving boundaries and unstable rules. The thesis argues that anti-social acts manifest a failure of the social pact, which in turn results in a failure of the primordial Oedipal pact. It also argues that antisocial acts are a communication in an incommunicable world.
