| Rationalizing the usage of boolean variables to represent propositional features and functions in this manner, I can now discuss these concepts in greater detail, introducing additional notation along the way. | | Rationalizing the usage of boolean variables to represent propositional features and functions in this manner, I can now discuss these concepts in greater detail, introducing additional notation along the way. |

| 1. The sign "xi", appearing in the contextual frame "_ : Bn >B", whether explicitly or implicitly, can be interpreted as denoting the ith coordinate function xi : Bn >B. The entire collection of coordinate maps in X = {xi} contributes to the definition of the "coordinate space" or "vector space" X : Bn, notated as follows: | | 1.
