We count objects that are distinct, not the same.
Drawing a distinction separates what an object is from what it is not. An object is in fact a relationship between these two opposites.
In the sections above, we explored how a sheep (a) can be counted by making a tally mark, then the tally mark can be counted by sliding a bead across a wire in an abacus (c).
Each “what is an object” is separated by a “what is not an object” and each “what is not an object is separated by a “what is an object”. The two are mutually exclusive. The same number is counted whether we count “what is an object”s or the “what is not an object”s.
