[영문]Evidence from two studies of social exclusion based in England are drawn on to suggest that responsible agency can be seen as a feature of resilience. I argue that this agency, or capacity to act effectively in the world, is developed relationally and is evident in people's thoughtful actions in their worlds, but is also contingent on the affordances for such action in any environment. That is, resilience can be seen as responsible engagement with one's world as well as a capacity to withstand difficulties. The theoretical basis of this argument is Cultural Historical Activity Theory (CHAT) which proposes that we are shaped by but also shape our worlds. The implications for professional practices are discussed.
