  Nevertheless, Kaplan’s theory still has implications for utterances and speech acts. Suppose that Mary utters the sentence ‘I am a philosopher’ in world \(w\). Mary’s utterance has an agent in \(w\), namely Mary, and it occurs at a certain location and time in \(w\). So, her utterance in \(w\) determines a Kaplanian context. Call this context ‘Mary’s context’. On Kaplan’s theory, the sentence Mary utters has a content in Mary’s context, namely the singular proposition that Mary is a philosopher. If Mary utters the sentence assertively, then she (probably) asserts the content of that sentence in her context. So, Kaplan’s theory, together with other plausible assumptions, has important implications for what Mary asserts in her utterance.
