 The descriptive conventions associate sentences with (types of) ways for things to be: ways for situations, things, events, etc. to be. For instance, the sentence “The cat is on the mat” is associated with a type of way for things to be in which the cat is on the mat. A variety of different historic situations might be of that type. For instance, one historic situation of that type might involve Logos (Derrida’s cat), while a different historic situation of the same type might involve Nothing (Sartre’s cat). Similarly, cat-mat pairings that took place at different times would be different historic situations or events and yet might be of the same type.
