 What Cassirer calls representative symbolic meaning, a product of the representative function (Darstellungsfunktion) of thought, then has the task of precipitating out of the original mythical flux of “physiognomic” characters a world of stable and enduring substances, distinguishable and reidentifiable as such. Working together with the fundamentally pragmatic orientation towards the world exhibited in the technical and instrumental use of tools and artifacts, it is in natural language, according to Cassirer, that the representative function of thought is then most clearly visible. For it is primarily through the medium of natural language that we construct the “intuitive world” of ordinary sense perception on the basis of what Cassirer calls intuitive space and intuitive time. The demonstrative particles (later articles) and tenses of natural language specify the locations of perceived objects in relation to the changing spatio-temporal position of the speaker (relative to a “here-and-now”), and a unified spatio-temporal order thus arises in which each designated object has a determinate relation to the speaker, his/her point of view, and his/her potential range of pragmatic activities. We are now able to distinguish the enduring thing-substance, on the one side, from its variable manifestations from different points of view and on different occasions, on the other, and we thereby arrive at a new fundamental distinction between appearance and reality. This distinction is then expressed in its most developed form, for Cassirer, in the linguistic notion of propositional truth and thus in the propositional copula. Here the Kantian “categories” of space, time, substance, and causality take on a distinctively intuitive or “presentational” configuration.
