If the linguistic behavior blocks conceptual development, if it militates against abstraction and mediation, if it surrenders to the immediate facts, it repels recognition of the factors behind the facts, and thus repels recognition of the facts, and of their historical content. In and for the society, this organization of functional discourse is of vital importance; it serves as a vehicle of coordination and subordination. The unified, functional language is an irreconcilably anti-critical and anti-dialectical language. In it, operational and behavioral rationality absorbs the transcendent, negative, oppositional elements of Reason.
....any mode of thinking which is not confined to pragmatic orientation within the status quo - can recognize the facts and respond to the facts only by "going behind" them. Experience takes place before a curtain which conceals and, if the world is the appearance of something behind the curtain of immediate experience, then, in Hegel's terms, it is we ourselves who are behind the curtain. We ourselves not as the subjects of common sense, as in linguistic analysis, nor as the "purified" subjects of scientific measurement, but as the subjects and objects of the historical struggle of man with nature and with society. Facts are what they are as occurrences in this struggle. Their factuality is historical, even where it is still that of brute, unconquered nature.
