 Among the most frequently-identified principles that are introspectively brought forth – and one that was the standard for German Idealist philosophers such as Fichte, Schelling and Hegel who were philosophizing within the Cartesian tradition – is the principle of self-consciousness. With the belief that acts of self-consciousness exemplify a self-creative process akin to divine creation, and developing a logic that reflects the structure of self-consciousness, namely, the dialectical logic of position, opposition and reconciliation (sometimes described as the logic of thesis, antithesis and synthesis), the German Idealists maintained that dialectical logic mirrors the structure not only of human productions, both individual and social, but the structure of reality as a whole, conceived of as a thinking substance or conceptually-structured-and-constituted being.
