Two mutually exclusive same-type sets can become one same-type set, by crossing a boundary. Statements {contraction statement} can name two classes {categorizing, laws of form} and a relation {description, laws of form}, such as equality, with a reference point from which to relate members. Instructions {selection rule, laws of form} can be about how to select members. Processes can cross boundaries.
