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. A deductive argument is sound if and only if it is both valid , and all of its premises are actually true.

## What is a valid argument philosophy?

## What makes a logical premise strong?

Logical strength is the degree of support that the premises , if true, confer on the conclusion. This attribute applies to both deductive arguments (by virtue of validity) and inductive arguments (by virtue of inductive strength.) A good deductive argument is not only valid, but is also sound.
