Abstract
In the first part, the concept of instrumental reason is defended. Although we live in the age of pluralism, in which a tendency prevails to put all types of rationality on the same plane, there is a rationality that has a unique position: the instrumental rationality.
The article then examines Lukács's roots of this concept and its elaboration by Adorno and Horkheimer. The second part refers to the current transformation of instrumental reason that these authors could not register.
Instrumental reason is changed so that it can connect several seemingly incoherent elements: postmodern non-objectivity, social and ecological normativity, and reified imperatives of capitalism. This formation is here called over-instrumental instrumental reason.
In conclusion, the article deals with the question of how its non-instrumental component to exempt from its instrumental ones.
