Emerson’s Nature (1836) says some interesting things about figurative language, mostly in Chapter IV.

Chapter IV LANGUAGE

Language is a third use which Nature subserves to man. Nature is the vehicle, and threefold degree.

1. Words are signs of natural facts.
2. Particular natural facts are symbols of particular spiritual facts.
3. Nature is the symbol of spirit.

1. Words are signs of natural facts. The use of natural history is to give us aid in supernatural history: the use of the outer creation, to give us language for the beings and changes of the inward creation. Every word which is used to express a moral or intellectual fact, if traced to its root, is found to be borrowed from some material appearance. Right means straight; wrong means twisted. Spirit primarily means wind; transgression, the crossing of a line; supercilious, the raising of the eyebrow. We say the heart to express emotion, the head to denote thought; and thought and emotion are words borrowed from sensible things, and now appropriated to spiritual nature. Most of the process by which this transformation is made, is hidden from us in the remote time when language was framed; but the same tendency may be daily observed in children. Children and savages use only nouns or names of things, which they convert into verbs, and apply to analogous mental acts.

2. But this origin of all words that convey a spiritual import, -- so conspicuous a fact in the history of language, -- is our least debt to nature. It is not words only that are emblematic; it is things which are emblematic. Every natural fact is a symbol of some spiritual fact. Every appearance in nature corresponds to some state of the mind, and that state of the mind can only be described by presenting that natural appearance as its picture. An enraged man is a lion, a cunning man is a fox, a firm man is a rock, a learned man is a torch. A lamb is innocence; a snake is subtle spite; flowers express to us the delicate affections. Light and darkness are our familiar expression for knowledge and ignorance; and heat for love. Visible distance behind and before us, is respectively our image of memory and hope.
