This search for order pushes one to seek out under-lying patterns and trends, to find relations that may betypical and causal.
Finding order and relations (and their particular types), is a form of linking ideas found in some of the more complex zettelkasten and knowledge management spaces. It's not as explicit here and he doesn't seem to be focusing on stating or writing explicit links within his notes. He does, however, place some focus on the quality and types of links he's making (or at least thinking about), something which isn't frequently seen in the current PKM space. For example, no one is creating user interfaces that show links between ideas which are opposite (or in opposition or antonym relation) to each other.
