“…van Leeuwen and Wodak (1999) and van Leeuwen (2007) distinguish four sub-categories of justifying strategies, namely (1) authorisation through personal or impersonal institutionalised authorities (e.g., experts, parent, teacher, the law, through conformity ['everybody does it', use of statistics]), (2) instrumental or theoretical rationalisation through purposes (e.g., intrusion into privacy is justified 'to protects rights and freedom of others ' [van Leeuwen & Wodak, 1999, p. 106]), (3) moral abstractions and evaluations that link activities to values such as leadership and governmental control, economic values (economic interest of a country), values of public interest, national security or public order, and (4) mythopoesis through telling stories. Similar legitimation strategies were also used in Schulze's (2015) analysis of the surveillance discourse of German politicians. In addition, van Dijk (2006, p. 380) describes various forms of positive self-presentation and negative other-presentation through 'enhancing the power, moral superiority and credibility of the speaker(s), and discrediting dissidents, while vilifying the Others, the enemy; the use of emotional appeals; and adducing seemingly irrefutable proofs of one's beliefs and reasons'.…”
