“The affair of love, which, out of conformity with the Stoic philosophy, we shall here treat as a disease.”—Fielding's Tom Jones. IT has been pointed out that a motif or idea which plays an outstanding part in a poet's imagination and recurs frequently in his invention, is likely also to manifest itself in the form of his linguistic expression. It will crop up wherever the poet embellishes his discourse with simile, wherever emotional tension drives him to metaphoric expression, i.e., to the substitution of a word which carries more feeling than the word of common usage, or to an effort to express an idea which cannot properly be conveyed by the vocables at his disposal. This principle, it appears to me, becomes particularly significant from an æsthetic point of view when it manifests itself, as it sometimes does, with unusual strength within the scope of a single work. It may then give a very decided color and tone to the language of the whole work, producing metaphor after metaphor, simile after simile, all harping on one dominant theme throughout the book and so playing a continuous accompaniment, as it were, which keeps a major theme of the composition ringing in our ears as the story progresses through other motifs. This theme then becomes a style determinant, shaping the linguistic expression throughout a work of considerable length and making for a uniformity of tone.
