flawed arguments

so if a premise is invalid because it is not "true" then it becomes a flawed argument? for example two the premises logically follow the conclusion but since it is not " true" is not valid?

@naty0405,

No, the argument can have false premises and/ or a false conclusion and still be valid. The only rule is that if an argument has all true premises, it must have a true conclusion. Consider the following argument for example:

(1) All animals can fly
(2) Bat is an animal
(3) Therefore, bat can fly.

The first premise is false, the conclusion is true, and the argument overall is valid. Remember that validity only concerns the logic of the argument not the content.

Let me know if you have any further questions.
