QUOTATION
In quoting of books, quote such authors as are usually read; others you may read for your own satisfaction, but not name them.
Quoting of authors is most for matter of fact; and then I write them as I would produce a witness; sometimes for a free expression, and then I give the author his due, and gain myself praise by reading him.
To quote a modern Dutchman where I may use a classic author, is as if I were to justify my reputation, and I neglect all persons of note and quality that know me, and bring the testimonial of the scullion in the kitchen.—J. Selden. Table Talk.
