 Enumeration2 is “a preliminary survey or setting out of the grounds of a demonstration” (Beck 1952: 143; based on Rule 7, AT 10: 388–392, CSM 1: 25–28). Here, enumeration precedes both intuition and deduction. Enumeration2 determines (a) whatever simpler problems are contained in a complex problem, and (b) the order in which each of these problems must be solved, beginning with the simplest problem of all (for an example, see  Section 3).
