Can an argument be sound but invalid?
Question originally answered: Can a sound argument be invalid.
No, it cannot.
A sound argument is defined as a valid argument, with the extra property that the premises of the argument are true.
A valid argument is an argument which has the property that if the premises are true that then the conclusion must be true..
Are invalid arguments weak?
If a deductive argument is valid, then we go ahead and check the factual claim, because only then is it possible that the argument might be sound. An invalid argument is always unsound. An argument is sound if it is valid and the premises are all actually true.
Are all inductive arguments invalid?
Inductive argument: involves the claim that the truth of its premises provides some grounds for its conclusion or makes the conclusion more probable; the terms valid and invalid cannot be applied. … If this is possible, the argument is invalid. Validity and invalidity apply only to arguments, not statements.
What makes an inductive argument valid?
Inductive validity means that when one reasons inductively, such reasoning will contain three elements: 1) a premise (the first guiding point), 2) supporting evidence (what makes you believe the premise is true), and 3) a conclusion that is true and viable (valid) AS FAR AS YOU KNOW.
What are some examples of inductive arguments?
An example of inductive logic is, “The coin I pulled from the bag is a penny. That coin is a penny. A third coin from the bag is a penny. Therefore, all the coins in the bag are pennies.”
What is valid and invalid arguments?
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.
What is an example of an invalid argument?
An argument can be invalid even if the conclusion and the premises are all actually true. To give you another example, here is another invalid argument with a true premise and a true conclusion : “Paris is the capital of France. … The premises and the conclusion of an invalid argument can all be true.
What is an example of deductive and inductive arguments?
Deductive and inductive refer to how the arguer is claiming the premises support the conclusion. For example, the following is a deductive argument because I am claiming the conclusion must follow if the premises are assumed true: All whales are mammals. Shamu is a mammal.
Can valid arguments have false premises?
A valid argument can have false premises; and it can have a false conclusion. But if a valid argument has all true premises, then it must have a true conclusion.
What is the difference between inductive and deductive?
In logic, we often refer to the two broad methods of reasoning as the deductive and inductive approaches. Deductive reasoning works from the more general to the more specific. … Inductive reasoning works the other way, moving from specific observations to broader generalizations and theories.
What does invalid argument mean?
An invalid argument is a argument in which the premises do not provide conclusive reasons for the conclusion.
What is weak inductive argument?
A weak inductive argument is one where the conclusion probably would not follow from the premises, if they were true.
