Wissenschaft der Logik.

Hegel's work The Science of Logic (German: Wissenschaft der Logik) outlined his vision of logic, which is an ontology that incorporates the traditional Aristotelian syllogism as a sub-component rather than a basis. For Hegel, the most important achievement of German Idealism, starting with Kant and culminating in his own philosophy, was the demonstration that reality is shaped through and through by mind and, when properly understood, is mind. Thus ultimately the structures of thought and reality, subject and object, are identical. And since for Hegel the underlying structure of all of reality is ultimately rational, logic is not merely about reasoning or argument but rather is also the rational, structural core of all of reality and every dimension of it. Thus Hegel's Science of Logic includes among other things analyses of being, nothingness, becoming, existence, reality, essence, reflection, concept, and method. As developed, it included the fullest description of his dialectic.
