When we read, another person thinks for us: we merely repeat his mental process. (...) For the more one reads the fewer are the traces left of what one has read; the mind is like a tablet that has been written over and over. Hence it is impossible to reflect; and it is only by reflection that one can assimilate what one has read if one reads straight ahead without pondering over it later, what has been read does not take root, but is for the most part lost. Indeed, it is the same with mental as with bodily food: scarcely the fifth part of what a man takes is assimilated; the remainder passes off in evaporation, respiration, and the like.
— Schopenhauer
The main premise is there though — notes are short, they usually contain one idea, even if I can't name it yet (this also leads to interesting note titles, like spreadsheets might be a wrong model, or understanding requires effort). Notes are interlinked through direct links, and automatic backlinks (via muninn cli tooling). If I have a bunch of notes which seem related in some way, I create index note to collect them together, enforcing a specific point of view. Single note can be in multiple different indexes that way (connections are usually better than taxonomies).
