Reason that opposes the established order is historical Reason.

Evidence

When historical content enters into the dialectical concept and determines methodologically its development and function, dialectical thought attains the concreteness which links the structure of thought to that of reality. Logical truth becomes historical truth. The ontological tension between essence and appearance, between “is” and “ought” becomes historical tension, and the “inner negativity” of the object-world is understood as the work of the historical subject—man in his struggle with nature and society. Reason becomes historical Reason. It contradicts the established order of men and things on behalf of existing societal forces that reveal the irrational character of this order—for “rational” is a mode of thought and action which is geared to reduce ignorance, destruction, brutality, and oppression. — Herbert Marcuse, One-Dimensional Man, 534
