A deductive argument is said to be valid when the inference from premises to conclusion is perfect. Here are two equivalent ways of stating that standard: If the premises of a valid argument are true, then its conclusion must also be true.

(Considering the premises as a set of propositions, we will say that the premises are true only on those occasions when each and every one of those propositions is true.)
