It is a near truism of philosophy of language that sentences are prior to words--that they are the only things that fundamentally have meaning. Robert's Stainton's study interrogates this idea, drawing on a wide body of evidence to argue that speakers can and do use mere words, not sentences, to communicate complex thoughts.

Some twenty years ago, semanticists of natural language came to be overwhelmed by the problem of semantic analysis of belief sentences (and sentences reporting other kinds of propositional attitudes): the trouble was that sentences of the shapes X believes that A and X believes that B appeared to be able to have different truth values even in cases when A and B shared the same intension, i.e. were, from the viewpoint of intensional semantics, synonymous 1 . Thus, taking intensional semantics for granted, belief sentences appeared to violate the principle of intersubstitutivity of synonyms. The verdict of the gurus of intensional semantics was that hence intensional semantics is inadequate, or at least insufficient for the purposes of analysis of propositional attitudes; and that we need a kind of a ‘hyperintensional semantics’.

Propositional attitude ascribing sentences seem to give rise to failures of substitution. Is this phenomena best accounted for semantically, by constructing a semantics for propositional attitude ascribing sentences that invalidates the Substitution Principle, or pragmatically? In this paper I argue against semantic accounts of such phenomena. I argue that any semantic theory that respects all our apparent substitution failure intuitions will entail that the noun-phrase position outside the scope of the attitude verb is not open to substitution salva veritate, which is counter-intuitive.

It is commonly assumed that natural languages, construed as sets of sentences, contain denumerably many sentences. One argument for this claim is that the sentences of a language must be recursively enumerable by a grammar, if we are to understand how a speaker-hearer could exhibit unbounded competence in a language. The paper defends this reasoning by articulating and defending a principle that excludes the construction of a sentence non-denumerably many words long.
