If premise is true then conclusion must be everything is true a: top down logic, validity, soundness, an argument is valid if it is impossible for its premises to be true and for its conclusion to be false, valid = conclusion necessarily follows from true ( in the logical sense, an argument is sound if and only if it has all true premises, sound = valid and true premise (true to what things really are)
