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 there any good invalid arguments?

Which kinds of arguments can either be cogent or Uncogent?

As such, we do not speak of validity/invalidity or soundness/unsoundness when it comes to inductive arguments. Instead, inductive arguments are either strong/weak or cogent/uncogent. A strong, inductive argument is such that that it is improbable that the premises are true and the conclusion is false.

Is it possible to have an argument that is neither strong nor cogent?

How do you know if an argument is cogent?

A cogent argument is by definition non-deductive, which means that the premises are intended to establish probable (but not conclusive) support for the conclusion. Furthermore, a cogent argument is strong, so the premises, if they were true, would succeed in providing probable support for the conclusion.

Are all weak arguments Uncogent?

A strong argument is uncogent when at least one of the premises is false. All weak arguments are uncogent, since strength is a part of the definition of cogency.

What is an example of a cogent argument?
