The following essay is composed of two parts: chapter I tries to trace the main intention for Hans Blumenberg's "Theorie der Unbegrifflichkeit", which was developed between 1960 and 1980, and wants to integrate it into the transdisciplinary paradigm of the 'prelogical' or 'savage thought' since 1900. Chapter II describes Blumenberg's speculative approach to the hypothetical 'primal scene' of anthropogenesis by linking anthropology and aesthetics.
