Tateando ao menos duas fronteiras de um campo para a comunicação

Abstract

The communication, understood as the main practice that creates the public space, raises a field of knowledge, still in formation, which aims at understanding the practice and the communicational nature ofthe public space. There are plural efforts that intend to create the autonomy ofthis field, according to several theoretical paradigms. A central question that guides the article is: can concepts and notions o f other domains win a new width in the field ofthe communication? In other words: can these ideas, that are strange to the field of communication in their origins, be helpful to this field when it needs to think itself?
