Discourse spaces are approached in linguistics from two perspectives. First, they are viewed as intra-discursive universes. One such universe would be a discourse space which represents a text world. The elements of this kind of discourse space include the deictic center from which the narrative is done, the narrator’s point of view, the displacement of the point of view and its vector orientation. A different kind of intra-discursive universe would be a discourse space as a cognitive and pragmatic context generated by knowledge (propositions) contained in a discourse. Second, discourse spaces are considered as extra-discursive universes, such as text spaces created by special categories of authors. In this article discourse spaces are understood as extra-discursive universes encompassing interdependent discourses which coexist and function together within the space boundaries. The systemic criteria of acceptability, consistency and disambiguation / interpretation are singled out. These criteria provide the operational basis for the collection of data on variation of discourse spaces. Three types of them are distinguished: physical, virtual and logical discourse spaces. Viewed in this perspective, the notion of discourse space allows to go beyond an individual discourse to the level of systematization of discourses.
