In everyday English usage, the words ‘literal’ and ‘figurative’ are normally taken to be opposite in meaning. It is an opposition with very ancient roots. One of its forbears was the medieval theory of Scriptural hermeneutics, which distinguished among the literal, allegorical, moral, and anagogic senses of Scripture. This itself had an ancestry in pre-Augustinian times: Augustine tells in his Confessions how he learned from Ambrose the trick of interpreting Scripture figuratively, thus eliminating the problems and contradictions created by a literal reading. Earlier still, the distinction and the opposition were at least implicit in Poetics 21, where Aristotle differentiated between the standard or normal name for a thing, and various other types of name among which he listed metaphor. The antonymy of the literal and the figurative is therefore deeply embedded in our intellectual history, and it is perhaps for this reason that it has remained, to a large extent, unexamined and unquestioned.
