“Some books are to be tasted, others to swallowed, and some few to be chewed and digested; that is, some books are to be read only in parts; others to be read, but not curiously; and some few to be read wholly, and with diligence and attention.”
–Francis Bacon, “Of Studies” in The Works of Francis Bacon (New York: Hurd and Houghton, 1869), 12: 252-253.
