Emily Dickinson Lexicon

CON'TRAST, n.

1. Opposition or dissimilitude of figures, by which one contributes to the visibility or effect of the other. – Johnson. Contrast, in this sense, is applicable to things of a similar kind. We never speak of a contrast between a man and a mountain, or between a dog and a tree; but we observe the contrast between an oak and a shrub, and between a palace and a cottage.
2. Opposition, or difference of position, attitude, &c., of figures, or of their several members; as, in painting and sculpture.
3. Opposition, of things or qualities; or the placing of opposite things in view, to exhibit the superior excellence of one to more advantage. What a contrast between modesty and impudence, or between a well-bred man and a clown!
