Discourse analysis enables the identification of what social actors say and do but also of what they represent in terms of values and motivation Such an analysis can also unearth ideological representations which legitimize the reproduction of social structures, irrespective of whether such representations reflect some objective reality or not. In their turn, such structures are contingent and incomplete, and are subject to changes. Discourse analysis examines their political and historical construction and functioning. What this approach does is help us understand how certain facts and non-facts make it to the political agenda whilst others do not, and how they are interpreted within the public sphere.
