This essay seeks to demonstrate that the practice of phenomenological philosophy entails a practice of social and political criticism. The original demand of phenomenology is that theoretical and scientific judgments must be based upon the giving of the ‘things themselves’ in self-evident intuition. The continuous radicalization of this demand is what characterizes phenomenological philosophy and determines a practice of social and political criticism which can be traced through four phases: 1. a critique of institutions through the method of unbuilding (Abbau, (...) Destruktion, déconstruction); 2. presencing, or coming into presence, that directs one’s attention to the social movements of one’s time through which that which is pressed-out of the social form manifests itself; 3. authentic being-with (Mitsein) in which the sociality of human life is brought to the limit-condition of human life in being-toward-death; 4. nothingness, or negation, in which that which withdraws in any manifestation is incapable of a Hegelian re-immanentization as negation of the negation and thus points to an ethical dimension outside of history.
