Lord Chesterfield, Letters to His Son (122):
You cannot study much in the Academy; but you may study usefully there, if you are an economist of your time, and bestow only upon good books those quarters and halves of hours, which occur to everybody in the course of almost every day; and which, at the year’s end, amount to a very considerable sum of time. Let Greek, without fail, share some part of every day; I do not mean the Greek poets, the catches of Anacreon, or the tender complaints of Theocritus, or even the porter-like language of Homer’s heroes; of whom all smatterers in Greek know a little, quote often, and talk of always; but I mean Plato, Aristoteles, Demosthenes, and Thucydides, whom none but adepts know. It is Greek that must distinguish you in the learned world, Latin alone will not: and Greek must be sought to be retained, for it never occurs like Latin. When you read history or other books of amusement, let every language you are master of have its turn, so that you may not only retain, but improve in everyone.
