Being, in whose name Heidegger's philosophy increasingly concentrates itself, is for him-as a pure self-presentation to passive consciousness-just as immediate, just as independent of the mediations of the subject as the facts and the sensory data are for the positivists. In both philosophical movements thinking becomes a necessary evil and is broadly discredited. Thinking loses its element of independence. The autonomy of reason vanishes: the part of reason that exceeds the subordinate reflection upon and adjustment to pre-given data. With it, however, goes the conception of freedom and, potentially, the self-determination of human society.
