 Traditionally, semantics has been denotational and representational, consisting in a homomorphic valuation from expressions to some range of objects. This approach risks ontological explosion, first in hypostatizing denotations for empty names, predicates, conjunctions, prepositions and so on…, then in seeking values for false propositions in the form of non actual states of affairs. It is also regressive, since a criterion is now needed to determine which non-actual states of affairs are possible, which simply repeats the initial problem. Talk of possible worlds is an attractive metaphor, but does little useful philosophical work and much harm.
