Language IS understanding, which makes an author's use of language a clear guide to the nature of that author's understanding. As social decay is caused by a widespread decay in the clarity of thought, this must obtain a widespread decay in the clarity of expression. The symptoms of which can only be a general discarding of the disciplines of spelling, punctuation and grammar, along with the loss of short plain sentiments; evidence that is available to everyone and easy to recognise. Qualities that make consideration of the general use of language an ideal tool to diagnose decline and explain why the history of English literature is a diary of the rise and decline of English speaking civilization.

The general deterioration in the quality of expression can be easily seen by:

1. Comparing books published in the eighteenth century with contemporary works, e.g. two works on the subject of Economics. "An Inquiry Into the Nature and Causes of the Wealth of Nations" written in 1776 by Adam Smith, is lucid, whereas "The General Theory Of Employment, Interest, And Money" written in 1935 by John Maynard Keynes, is incomprehensible—it is not plain English.

2. Reading the book 'Death Sentence: The Decay Of Public Language' by Don Watson, published in 2003.
