Pragmatism, in trying to turn experimental physics into a prototype of all science and to model all spheres of intellectual life after the techniques… - Max Horkheimer

No criticism can be brought against a branch of technical science from outside; no thought fitted out with the knowledge of a period and setting its course by definite historical aims could have anything to say to the specialist. Such thought and the critical, dialectical element it communicates to the process of cognition, thereby maintaining conscious connection between that process and historical life, do not exist for empiricism; nor do the associated categories, such as the distinction between essence and appearance, identity in change, and rationality of ends, indeed, the concept of man, of personality, even of society and class taken in the sense that presupposes specific viewpoints and directions of interest.

With the abolition of otium and of the ego no aloof thinking is left. … Without otium philosophical thought is impossible, cannot be conceived or understood.

Thought must be judged by something that is not thought, by its effect on production or its impact on social conduct, as art today is being ultimately gauged in every detail by something that is not art, be it box-office or propaganda value.
