A valid logical argument is one in which the truth of the premises indeed guarantees the truth of the conclusion. For example, the following logical argument is valid: If the forecast calls for rain, I will not wear sandals. The forecast calls for rain. Therefore, I will not wear sandals. This argument has two premises which, together, guarantee the truth of the conclusion. An argument can be logically valid even if its premises are false. See also invalid argument and sound argument.
