A '''valid argument''', in [[formal logic]], one in which the conclusion is correctly derived from the premises. That is, a valid argument is one in which, if the premises are true, the conclusion must also be true.
{{quotebox|A deductive argument is said to be valid when the inference from premises to conclusion is perfect. [http://www.philosophypages.com/lg/e01.htm Arguments and Inference: truth and validity] }}
