actualists disagree with both possibilists and Meinongians whether there are possible objects, e.g. unicorns, while actualists and possibilists disagree with Meinongians whether there are impossible objects, e.g. round squares. The disagreements between these three views touch many areas in philosophy, including the semantics of natural language and the problem of intentionality. This is due to the fact that various expressions commonly used in natural language seem to refer to merely possible and in some cases even impossible objects. Since actualists deny the existence of such objects, it would seem that they are committed to the view that these expressions don't refer to anything and are therefore meaningless. This would be a rather unintuitive consequence of actualism, which is why actualists have proposed different strategies for different types of expressions in order to avoid this conclusion. These strategies usually involve some kind of paraphrase that transforms a sentence with apparently problematic ontological commitments into one that is free of such commitments. Names and definite descriptions Names of non-existent entities, like the 'planet' Vulcan, or names of fictional characters, like Sherlock Holmes, are one type of problematic expressions. These expressions are usually considered meaningful despite the fact that neither Vulcan nor Sherlock Holmes have actual existence. Similar cases come from definite descriptions that fail to refer, like "the present king of France". Possibilists and Meinongians have no problem to account for the meaning of these expressions: they just refer to possible objects. (Possibilists share this problem with the actualists in case of definite descriptions involving impossibility like "the round square") A widely known solution to these problems comes from Bertrand Russell. He proposed to analyze both names and definite descriptions in terms of quantified expressions. For example, the expression "The present king of France is bald" could be paraphrased as "there is exactly one thing that is currently king of France, and all such things are bald". This sentence is false, but it doesn't contain a reference to any non-actual entities anymore, thanks to the paraphrase. So the actualist has solved the problem of accounting for its meaning. Intentional attitude reports Intentional attitude reports about non-actual entities are another type of problematic cases, for example "Peter likes Superman". Possibilists can interpret the intentional attitude, in this case the liking, as a relation between Peter, an actual person, and Superman, a possible person. One actualist solution to this problem involves treating intentional attitudes
