Abstract

Some philosophy – Wittgenstein's would be an example – is written in clear sentences, yet most people find it obscure at a first reading. This is because the prime location of clarity in philosophy is not sentences but structures. Only if a reader can relate what he is currently reading to a wider framework does he know where he is. Coherent utterance in all discursive media – not only language but mathematics, for example, or music – possesses two kinds of structure at the same time. In this article these are distinguished, and their radically different relationships with language shown. In the process, the commonest causes of unclarity are also identified.
