Sein und Nichts

This work is the final volume of a Trilogy of Being , the first two volumes of which, Structure and Being and Being and God , were published in 2006 and 2010, respectively. This volume presents a comprehensive theory on Being comprising two (sub) theories: the theory of (Being of) beings (ontology) and the theory of Being as such (einailogy). The theory of Being is the result of the systematic development of the difference between being(s) and Being and of the clarification of the concept of nothingness.
