 Consider a very simple framework with three primitive sentences: \(h\) (for the state hot), \(r\) (for rainy) and \(w\) (for windy). This framework generates a very small space of eight possibilities. The eight maximal conjunctions (like \(h \amp r \amp w, {\sim}h \amp r \amp w,\) etc.) of the three primitive sentences and of their negations express those possibilities.
