 According to MacFarlane’s theory the truth of a statement should be relativised to both a context of utterance and a context of assessment. The context of utterance is the context in which the speech act is made. The context of assessment is the context in which we assess the speech act. According to the theory, a statement \(S\) is true as used in the context \(C\) and assessed in the context \(C'\), if and only if \(S\) is true at \(m\) for every chronicle \(c\) passing through \(m\) and \(m'\), where \(m\) and \(m'\) are moments within the contexts \(C\) and \(C'\) with \(m \le m'\). This means that a statement like “it will be sunny tomorrow” is true as uttered yesterday and assessed from today, given that it is in fact sunny today. But it will not be true assessed from yesterday, given that it was not settled yesterday that today would be sunny.
