Hegel's logic is a dialectical metaphysics, or system of dialectics; it is a development of the idea that thought and being are one active entity. The classic Aristotelian syllogism is included in Science of Logic as well; however, it is envisioned as a stage of the "initial unity of thinking and existence" rather than as an impersonal, formal tool of reasoning.



Hegel considered Immanuel Kant's assertion that thought shapes reality (being) from the inside out and that reality (being) is, in many ways, identical to thought to be the most significant contribution of German idealism, which began with Kant and culminated in his own philosophy. In the end, subject and object, thought, and existence have the same structural components. Hegel believed that all reality eventually has a rational structure, therefore logic is not just about reasoning or argumentation but also the rational, structural heart of all reality and all of its dimensions. As a result, analyses of being, emptiness, becoming, existence, reality, essence, reflection, concept, and method are among the topics covered in Hegel's Science of Logic. It contained the most thorough explanation of his dialectic as it was developed.
