Evaluation and Technical Reason

While Platonism holds that the Circle has a supernatural origin, it has difficulty explaining the derivation of the concept of Wheel from that source.  Likewise, Know-How seems independent of Pure Reason--of both the Theoretical and the Practical varieties.  Thus, the evaluation of Artifactuality, i. e. the world of what humans make, has an exclusively human, all too human source--Technical Reason, i. e. is opaque to any supernatural forces.  So, it may not be until his late, and brief, consideration of Architecture, in Twilight of the Idols, that Nietzsche entertains a clear exemplar of the scope of his theory of Evaluation.
