How to read a card

Every concept is a two-dimensional card. One axis defines it (what it is, what it is not, its essence, necessary conditions, common misconceptions); the other axis guides practice (how to deal with it, what to do, what to avoid, examples). Concepts form a tree, from broad ideas down to specific subtopics.
