In §§ 4–5, I examine the socio-evolutionary circumstances under which a closed combinatory, such as the one triggered by the Llullian art, was replaced by an open-ended combinatory, such as the one triggered by a card index based on removable entries. In early modernity, improvement in abstraction compelled scholars to abandon the idea that the order of knowledge should mirror the order of nature. This development also implied giving up the use of space as a type of externalization and as the main rule for checking consis-tency.
F*ck! I've been scooped!
Apparently I'm not the only one who has noticed this, though I notice that he doesn't cite Frances A. Yates, which would have certainly been the place for having come up with this historical background (at least that's where I found it.)
The Llullian arts can be more easily practiced with ideas placed on moveable index cards than they might be with ideas stored in one's own memory. Thus the index card as a tool significantly decreases the overhead and provides an easier user interface for permuting one's ideas and combining them. This decrease in mental work appearing at a time of information overload also puts specific pressure on the older use of the art of memory to put it out of fashion.
