The primary substance of the poetic imagination.
A metaphor is not merely a clever embellishment of the poet's truth.
It is often the only precise embodiment of that vision!
Nor is it a riddle to be solved or a semantic obstacle to be leapt over;
before the poem's meaning can be discovered?
It is in itself: a solution, a leap, a meaning, and a discovery!
~M. Haley, The Semeiosis of Poetic Metaphor~
