Bust of Nietzsche. Max Klinger 1902.
They are residues of a dream world. The realization of dream elements, in the course of waking up, is the paradigm of dialectical thinking. Thus, dialectical thinking is the organ of historical awakening. Every epoch, in fact, not only dreams the one to follow but, in dreaming, precipitates its awakening. It bears its end within itself and unfolds it – as Hegel noticed – by cunning.
