Some ideas are neither thinkable nor knowable without language. At the same time, language, as a privileged form of representation, exacts a price (Rorty, 1979). Language can homogenize; that is, it tends to treat things as members of a class—that is an oak tree, this is a cat… No doubt, classification is crucial. But oak trees are not all alike, nor are cats, dogs, houses, or clouds. To the extent that classification short-circuits the perceptual exploration of the individuality of objects and events, it undermines what can be known about them. In the ideal world we need to encourage and develop not only the ability to classify, but also the appetite to individuate.
One form of language is propositional: it is designed to provide precise relationships between subject and predicate and to diminish ambiguity—to the extent possible—between the linguistic terms employed and their referents. The language of science is an exemplar of propositional language. Mathematics, a nonlinguistic language, is the most compelling example of a precise “propositional” form.
Eisner, Elliot W. (1998) The Kind of Schools We Need. Heinemann: Portsmouth, NH.Poetry employs meaning systems that differ as much from literature as literature differs from science. Poetry may have no propositions whatsoever. Indeed, the primary meanings of poetry, like some of those in literature, are nondiscursive; that is, poetic meaning is obtained from the forms the language takes. These forms convey what, paradoxically, words cannot say.
