The aim of the paper is to show that Russell’s theory of denoting phrases (particularly, that of definite descriptions) is, first and foremost, a theory of logical form of sentences involving denoting phrases. A proper argument against this theory should impugn its capability to fulfil its task. This strategy is followed by Tichý’s argument from sentences concerning notional attitudes; unfortunately, it is unjustly ignored in the literature. On the other hand, the most popular counterarguments, such as Strawson’s well-known attack, are concerned with features that are irrelevant to Russell’s theory.
