”If for I want that glib and oily art,
To speak and purpose not…”
This is a quote from Shakespeare’s King Lear. It refers of course to rhetoric – that dangerous dark art of manipulating words to speak and purpose not! Rhetoric is still today seen as a dirty word that is often used to accuse adversaries of possessing a questionable disposition. For example, the media only really uses the word ‘rhetoric’ when they are talking about Donald Trump or North Korea (when they are talking of Obama they tend to use the word oratory).
