Having Meaning and Irony

According to the Semantic theory typically characterized as 'Platonist', words 'have meaning' because they are copies of self-subsisting Forms.  However, one shortcoming of that theory is one that Plato himself would have to acknowledge--its applicability to those situations in which Socrates communicates to Plato and others meanings that are the opposite of those possessed by the words that he utters, i. e. applicability to 'irony'.  Furthermore, such examples suggest a different genesis of the attribution of Meaning to Words: 1. The 'meaning' of words is their utterer's hoped-for response from an addressee; 2. The entire scenario is generalized as--a hypothetical generic utterer, projected as using words to elicit a hoped-for response, from a hypothetical generic addressee--resulting in the meanings of those words being conceived as 'generally accepted'; and 3. The abstraction of the those words and their acquired meanings from any interpersonal, purposive context.  That Plato himself illustrates a Semantic theory different than the one typically associated with his name is, of course, ironic.
