Famous quotes containing the words drug, reference and/or standard:
“Whoever grows angry amid troubles applies a drug worse than the disease and is a physician unskilled about misfortunes.”
—Sophocles (497–406/5 B.C.)
“I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.”
—Carolyn Wells (1862–1942)
“The art of advertisement, after the American manner, has introduced into all our life such a lavish use of superlatives, that no standard of value whatever is intact.”
—Wyndham Lewis (1882–1957)
