“Sophism sets in once philosophy is reduced to the level of mere discourse or conversation, that is, when it is cut off from the active prescription of its conditions and so considered “as detached from its act.” As soon as it is reduced to propositions or a discursive regime, philosophy is sophistic . For the “essence of philosophy lies in the act of grasping truths, and not in the rhetorical montage of its linguistic operation”
