 A useful way of visualizing the dual role played by possible worlds in a 2D framework is to construct a two-dimensional matrix (Stalnaker 1978). To represent Kaplan’s theory of indexicals, we array possible circumstances of evaluation along the horizontal axis and possible contexts of utterance along the vertical axis. Each horizontal row of the matrix represents the content the target expression would have if used in the context specified for that row. This content is (partially) represented by recording the extension of the term at each possible circumstance arrayed along the horizontal axis. This procedure is then repeated for each context listed along the vertical axis.
