TRUE: If an argument is sound, then it is valid and has all true premises. Since it is valid, the argument is such that if all the premises are true, then the conclusion must be true. A sound argument really does have all true premises so it does actually follow that its conclusion must be true.
STUDY. If a valid argument has a false conclusion, then it is unsound. True - A sound argument must have both a valid form and true premises.
A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. Otherwise, a deductive argument is said to be invalid.
True. A sound argument is one that is valid with all true premises. If an argument is valid, that means that IF the premises are true, then the conclusion must be true. And if an argument is sound, then the premises are true.
Sound Arguments Firstly, a sound argument is a deductive argument. It's trying to establish conclusive support for its conclusion. Secondly, the argument is valid: the premises, if true, would guarantee that the conclusion is also true. And on top of all that, the premises are actually true.
A sound argument is a valid argument with true premises. Which of the following best describes a premise of an argument: 1. a reason for accepting the conclusion of an argument.
Soundness: An argument is sound if it meets these two criteria: (1) It is valid. (2) Its premises are true. In other words, a sound argument has the right form AND it is true. Note #3: A sound argument will always have a true conclusion.
A sound argument is an argument that is valid and has true premises while an unsound argument is an argument that is invalid or has at least one false premises. Thus, this is the key difference between sound and unsound argument.
