Van Dijk (2003) stated that CDA is a proposition which emphases on how power abuse, dominance and inequality are exercise in the discursivity of the social and political context. However, Jorgensen and Phillips (2002) supposed CDA as a multi-disciplinary approach to analyse the relation between ‘discourse and social and cultural developments’ in cross cultural fields. Fairclough (1995) argued that the purpose of CDA is to “systematically expose the complex relationship of causality and determine between a) discursive practices, events, and texts, and b) wider social and cultural structures, relations and processes” (p.132). Another exponent of CDA, Janks (1997) observed CDA as a form of social practice whereby critical theories are practiced to analyse the opaque relationship. With reference to the idea above, CDA practices the critical theories which inspects language in relation to power and struggle over power which in return exposes the identities of oppressors. Meanwhile, Van Dijk (2003) said that CDA emphases on how a social group’s mental representation is inclined by social structures. In this event, the theme of a conversation may effect how people focus on the important information in a text or talk.
CDA is considered as an interdisciplinary multi-methodical approach rather than an isolated discipline on its own. Van Dijk (2009) stressed that CDA is a combination of critical theory and application rather than a critical analysis which therefore pointers to the term (critical discourse studies). Van Dijk (2009) and Wodak and Meyer (2009) delineated the aims and tenets of CDA which are engaged in reviewing recent CDA studies:
– CDA is problem-oriented rather than emphases on theory or a particular discipline as its implications are explicitly depicted in layman’s term to the society.
– CDA is an interdisciplinary as it contains various theory, methods and practical application in unbinding serious issues and problem in society.
– CDA is supposed as a social research as its critical research is concerned with social problems and the understanding of human rights, social inequality, power abuse in domains such as racism, classism, sexism, and etc.
– CDA is concerned in unprincipled problems which examine domination group of people whom are subjected to discursive injustice.
– CDA stresses spontaneous assessment as the need to shed light on the phenomenon under investigation and to provide justification on why certain interpretations are effective than others.
