### Soundness
# Soundness
Recall that in the definition of [deductive validity](Validity%20and%20entailment.md#validity) we do not say: an argument is valid iff if the premises _are true_ and the conclusion _is true_. We say _if it is possible for the premises to be true_. This is important: we are not interested in the actual truth of the premises or the conclusion.
