This seems relevant, so I'm going to post it here.
I read an essay for my upcoming exams that oddly has a lot to offer this discussion. Unfortunately, I'm having trouble finding it via my library's search engine. It's included in an anthology titled
Observing Complexity: Systems Theory and Postmodernity, edited by William Rasch and Cary Wolfe.
In the essay, which is by Rasch and titled "The Limit of Modernity: Luhmann and Lyotard on Exclusion," the author delineates between two varying modes of speaking about exclusion - the logical and the political (or moral). The author contends that (following systems theory) exclusion is an operation of the world; it is simply a process by which complex systems designate themselves and make decisions. Every decision necessitates an exclusion of some kind (I choose this and not this).
However, while exclusion in a logical sense is unavoidable, exclusion in a moral sense is to be avoided at all costs. We encounter a dilemma when we realize that the decision to include someone/something can only be done at the cost of excluding something else. All decisions necessitate an inclusion and an exclusion. Rasch argues that rather than admit defeat or privilege one side, we have to recognize that neither side is "right" in any kind of evaluative sense; rather, both sides simply operate according to different codes, and these codes remain incompatible with each other. In a politicized society, the inevitability of decisive operations will always be interpreted as oppressive:
More than a logical necessity, exclusion is thus read as a series of existential consequences of ideological choice. From such a political perspective, to maintain a logical or scientific (wissenschaftlich) observation of the logical necessity of exclusion is deemed an evasion or denial of the victimized other, if not, in fact, a further masculinist [Rasch is speaking specifically about patriarchal critique in this case] strategy of domination. Indeed, according to this view, logic itself, by hiding (excluding) the political analysis, becomes ideological.
Any attempt to appeal to logic in order to erase the political dynamics of social operations (or move past them, dissolve them, assuage them via appropriation) - that is, to exclude the logic of exclusion - becomes an ideological act because it appears to will the ignorance of political plight, or to make the assumption that such suffering is over, done, in the past.
