 Functors - Psychology Dictionary of Arguments
 
Functors: A functor in logic is a function that maps from one logical structure to another. It preserves the structure of the original logical structure, but it may change the specific values of the logical elements. For example, a functor could be used to map from a propositional calculus formula to a first-order logic formula. This functor would preserve the logical structure of the formula, but it would replace the propositional variables with predicate variables. See also Variables, Propositional calculus, Predicate calculus, Logic, Logical formuulas.
