#The sense of different names is different, even when their reference is the same. Frege argued that if an identity statement such as "[[Hesperus]] is the same planet as [[Phosphorus (morning star)|Phosphorus]]" is to be informative, the proper names flanking the identity sign must have a different meaning or sense. But clearly, if the statement is true, they must have the same reference.<ref>"On Sense and Reference", p. 25</ref> The sense is a 'mode of presentation', which serves to illuminate only a single aspect of the referent.<ref>"On Sense and Reference", p. 27</ref>
