Choosing an external system for knowledge keeping and production forces the learner into a deliberate practice and confronts them with their lack of understanding. This is a large part of the underlying value not only of the zettelkasten, but of the use of a commonplace book which Benjamin Franklin was getting at when recommending that one "read with a pen in your hand". The external system also creates a modality shift from reading to writing by way of thinking which further underlines the value.

What other building blocks are present in addition to: - modality shift - deliberate practice - confrontation of lack of understanding

Are there other systems that do all of these as well as others simultaneously?

mise-en-place is an example of a means of thinking externally with one's environment

'Memory crutch' implies a physical human failing that needs assistance rather than a phrase like aide-mémoire that doesn't draw that same attention.

Barthes kept his system to a 'strict format' of cards which were one quarter the size of his usual sheet of writing paper, though he did adjust the size over time as paper sizes standardized within Europe. Hollier indicates that the collection had considerable 'interior mobility' and the cards were constantly reordered with use. Barthes also apparently frequently annotated and altered his notes on cards, so they were also changing with use over time.

Did he make his own cards or purchase them? The sizing of his paper with respect to his cards might indicate that he made his own as it would have been relatively easy to fold his own paper in half twice and cut it up.

Were his cards numbered or marked so as to be able to put them into some sort of standard order? There's a mention of 'interior mobility' and if this was the case were they just floating around internally or were they somehow indexed and tethered (linked) together?

The fact that they were regularly used, revise, and easily reordered means that they could definitely have been used to elicit creativity in the same manner as Raymond Llull's combinatorial art, though done externally rather than within one's own mind.

spectacular intellectual feats exhibited in science and other areas of systematic enquiry, as well as in the arts, they need to understand the extent to which the mind is reliant upon external scaffolding.” (Ibid.)

Link this to the 9/8 zettel quote from Luhmann about writing being thinking.

Compare the ideas of visual thinking (visualizations) and a visualization of one's thinking being instantiated in writing along with the Feynman quote about the writing being the thinking. What ways are they similar or different? Is there a gradation in which one subsumes the other?

What does Annie Murphy Paul have to say on this topic in The Extended Mind?

Let's be honest that there are certainly methods for doing all of this within our brains and not needing to rely on external structures. This being said, using writing, literacy, and external structures does allow us to process things faster than before.

Can we calculate what the level of greater efficiency allows for doing this? What is the overall throughput difference in being able to forget and write? Not rely on communication with others? What does a back of the envelope calculation for this look like?
