I just learned about it when I googled the Rose of Temperaments after Luka mentioned it. I haven't looked into it though, nor am I familiar at all with Goethe, really.
But that is an interesting point of departure. If you'll permit a naive swing into computational theory...
I think there are these two variations of binary code, one called "return to zero" and one called "non-return to zero"
Return to zero
Non Return to Zero
Not quite sure about the technical side, but Return to Zero seems to have a strange liminal state
between a binary, while Non Return to Zero is a stricter binary. But somehow, they are both binary.
1 - With light/dark as presence/absence, one extremity is the absence (Non Return to Zero).
2 - With light/dark as positive/negative, the absence is between the extremities, which are both presences (Return to Zero).
These two seem to be a hugely impactful meta-dialectic of sorts, one that I think is worth understanding.
But I really should look into the Goethe theory more. You have any other leads?
