In simple terms, a metaphor shows us one thing as another, and in doing so extends the way we see the world, also often refreshing and enlivening our perception. In oral and written language, using the medium of picture imagery, metaphor speaks directly to our imaginative faculties, bypassing our rational brain. Such metaphoric byways and pathways enable us to explore the ideas, forces, and powers that lie behind or beyond our rational thought.
