Persuasion, even exaggeration, does not fit here. Artists with words perennially try to bridge this gap. Many philosophers, too, have tried to describe the relationship between language and truth. Social Philosophers such as George Steiner in such books as Language and Silence ponder the value and place of speech and its absence. Similarly, educationalists, centers of civic reform, institutes for civic society and such centers of language-excellence studies share in recent and contemporary attempts to reform language in the direction of that truth which is also compassion and insight.
Ancient philosophers can also help today.
In the ancient writings of Plato, the ideal and the real are inextricably linked. Computer programmers, poets, singers, orators, preachers and the purveyors of many kinds of 'literature' concur in the search for an 'ideal language'. This is question towards which world religions also have had their contributions. Judaism, Christianity and Islam agree with the need for words to express truth, and the importance of true witness. The Semitic religions understand that words can calm and heal or inflame and wound.
