A simile, to be perfect, must both illustrate and ennoble the subject; must show it to the understanding in a clearer view, and display it to the fancy with greater dignity; but either of these qualities may be sufficient to recommend it.... That it may be complete, it is required to exhibit, independently of its references, a pleasing image; for a simile is said to be a short episode.
Samuel JohnsonWhen the desire of wealth is taking hold of the heart, let us look round and see how it operates upon than whose industry or fortune has obtained it. When we find them oppressed with their own abundance, luxurious without pleasure, idle without ease, impatient and querulous in themselves, and despised or hated by the rest of mankind, we shall soon be convinced that if the real wants of our condition are satisfied, there remains little to be sought with solicitude or desired with eagerness.
Samuel JohnsonWhen a poet mentions the spring, we know that the zephyrs are about to whisper, that the groves are to recover their verdure, the linnets to warble forth their notes of love, and the flocks and herds to frisk over vales painted with flowers: yet, who is there so insensible of the beauties of nature, so little delighted with the renovation of the world, as not to feel his heart bound at the mention of the spring?
Samuel Johnson
