"Anyone who clearly sees how, after Socrates, that mystagogue of knowledge, one philosophical school after another, like wave after wave, arose in turn, and how an unimaginable universal greed for knowledge through the full extent of the educated world steered knowledge around on the high seas as the essential task for every person of greater capabilities, a greed which it has been impossible since then completely to expel from scientific knowledge, and how through this universal greed a common net of thinking was cast over the entire earth for the first time (with even glimpses of the rule-bound workings of an entire solar system)—whoever reminds himself of all this, together with that astonishingly high pyramid of contemporary knowledge, cannot deny that in Socrates we see a turning point and vortex of so-called world history."
