Von Bu ̈ low and Krusche analyze this system as a medium of “conversationwith oneself,” where the Zettelkasten stands in for lacking or absent inter-locutors.19
They write this, but was it before or after Luhmann wrote his essay on Communication with the Slip Box to suggest the idea? Presumably there was heavy influence here.
Ulrich von Bu ̈ low and Dorit Krusche have documented Blumenberg’selaborate method of systematically arranging excerpts from the vast varietyof texts he read: “In Blumenberg’s case, nearly all acts of reading, interpre-tation and ordering took material shape within the Zettelkasten.” 17
What sort of ordering did Blumenberg's zettelkasten exhibit?
17 “Bei Blumenberg haben nahezu alle Aspekte der Lektu ̈ re, der Interpretation und der Ordnung im Zettelkasten materielle Gestalt angenommen,” von Bu ̈ low and Krusche, “Vorla ̈ ufiges,” 275.
