| The main formal object under discussion is a [[logical operation]] on two [[logical value]]s, typically the values of two [[proposition]]s, that produces a value of ''false'' just in case the first operand is true and the second operand is false. By way of a temporary name, the logical operation in question may be written as Cond (''p'', ''q''), where ''p'' and ''q'' are logical values.
