In this euphemistic Bedlam, Louis Althusser would have felt at home.
Althusser observed that society consists of practices: economic, political and ideological. He defines a practice as:
"Any process of transformation of a determinate product, affected by a determinate human labour, using determinate means (of production)."
The economic practice (the historically specific mode of production, currently capitalism) transforms raw materials to finished products deploying human labour and other means of production in interactive webs. The political practice does the same using social relations as raw materials.
America's social superstructure, for instance, is highly ideological. The elite regards itself as the global guardian and defender of liberal-democratic and capitalistic values (labeled "good") against alternative moral and thought systems (labeled "evil"). This self-assigned mission is suffused with belligerent religiosity in confluence with malignant forms of individualism (mutated to narcissism) and progress (turned materialism).
Althusser's conception of ideology is especially applicable to America's demonisation of Saddam Hussein (admittedly, not a tough job) and its subsequent attempt to justify violence as the only efficacious form of exorcism.
People relate to the conditions of existence through the practice of ideology. It smoothes over contradictions and offers false (though seemingly true) solutions to real problems. Thus, ideology has a realistic attribute - and a dimension of representations (myths, concepts, ideas, images). There is harsh, conflicting reality - and the way that we represent it both to ourselves and to others.
"This applies to both dominant and subordinate groups and classes; ideologies do not just convince oppressed groups and classes that all is well (more or less) with the world, they also reassure dominant groups and classes that what others might call exploitation and oppression is in fact something quite different: the operations and processes of universal necessity"
(Guide to Modern Literary and Cultural Theorists, ed. Stuart Sim, Prentice-Hall, 1995, p. 10)
To achieve the above, ideology must not be seen to err or, worse, remain speechless. It, therefore, confronts and poses (to itself) only questions it can answer. This way, it is confined to a fabulous, fantastic, contradiction-free domain. It ignores other types of queries altogether. It is a closed, solipsistic, autistic, self-consistent, and intolerant thought system. Hence the United States' adamant refusal to countenance any alternative points of view or solutions to the Iraqi crisis.
"The objective internal reference ... the system of questions commanding the answers given."
The Problematic determines which issues, questions and answers are part of the narrative - and which are overlooked. It is a structure of theory (ideology), a framework and the repertoire of discourses which - ultimately - yield a text or a practice. All the rest is excluded.
