Postmodernism = Heidegger - Being

Many of the most celebrated postmodern theorists - the liquefactionists, essentially - are influenced by Heidegger, in a way, but they missed the entire point of Heidegger's philosophy.  Heidegger insisted, again and again, that what he writing was not epistemology, or existentialism, or the study of consciousness, or religion, or ethics, or least of all, politics - but rather ontology - the study of being.  The question he concerned himself with was the question of being.  We can think of several related questions, like "What is being?" or "What is nothing?" or "Why is there something rather than nothing?"  For Heidegger, none of these were the question of being.  That was a question that he did not even know how to pose, let alone answer.  

Is there any practical purpose or use to working on the question of being or any of these related questions?  I would say no.  You certainly cannot simply jump from one level to the other and assume that you understand everything.  There's a gap between the ontic and the ontological, such that success on one level is failure on the other.  So, while pondering being is interesting - for me, too - I wouldn't say that it leads to correct ethics or any other practical result.  It is sui generis.

Yet these latter "Heideggerians" studiously ignore the question of being.  The result is a philosophy that entirely worthless and pointless.  Remove being from Heidegger and there is nothing worthwhile left.
