Abstract
Intensional expressions can be either expressions containing free variables or expressions which do not contain such variables. An expression E, which contains no free variables, is an intensional expression if it can be transformed into a non-equivalent expression Eby replacing one of its constituents by an expression which is equivalent with that constituent.
