Abstract
The section dealing with the "phenomenology of consciousness" is finally dominated by the question, How does consciousness become self-consciousness, or how does consciousness become conscious that it is self-consciousness? This assertion, however, that consciousness is self-consciousness, is a central teaching of modern philosophy since Descartes. To this extent, Hegel’s idea of phenomenology lies in the Cartesian line. Contemporary parallels show how much this is the case, especially the quite unknown book of Sinclair, the friend of Hölderlin and Hegel, which deals with the Sphragis in the Rhein hymn, and is entitled Truth and Certitude. The work attempts, beginning quite explicitly with the Cartesian concept cogito me cogitare, to lead one along the path from certitude to truth in two rather similar fashions, through Fichte, and, almost contemporaneously, in Hegel.
