An argument is called “valid” when it’s form is correct and does not lend to a mistake in reasoning due to a faulty structure. An argument is deemed “cogent” when its form is valid and its premises are sound. In logic, “valid” means that if the premises are true, the conclusion is also true. A fallacy can occur when the form is adulterated to reach a false conclusion.
