It is important to be aware of the difference between truth and validity. Though often confused, they are in fact quite different. First, truth has to do only with statements, whereas validity has to do only with that structural arrangement of statements that we call an argument. Second, a statement is true if what it asserts reflects what is objectively the case. An argument is valid, to echo what was just said, if its structure is such that it will ensure a true conclusion—if its premises are true.
