Abstract
The consequences of Instrumental Reason have sparked a series of extensive discussions about the nature, origin and role of this Reason in contemporary societies, these deliberations were not limited to members of the Frankfurt School and its thinkers of their successive generations. Rather, it extended to include another group of thinkers, philosophers, and scholars who fall classified outside the intellectual space of the aforementioned school, Such as (Martin Heidegger, Jean-François Lyotard, Hannah Arendt, Michel Foucault, Zygmunt Bauman, Edgar Morin) and others. Although many of them meet the theses of the Frankfurt School in many of its main general lines, they were interested in researching The structure of this Reason, the investigation of its roots and its causes, the study of its symptoms and its manifestations, and they have resorted to new methods and approaches to criticize this Reason, deconstruct its fabric and dissect its system, and try to shed more light on the aspects that the leaders of the Frankfurt School neglected, or to deepen and broaden aspects of contemplation, or to address phenomena And practices hidden or unseen associated with this Reason and its ongoing process.
