“He who knows only his own side of the case, knows little of that.”

“How many a man has dated a new era in his life from the reading of a book.”

“Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.”

Not every book deserves the same kind of attention; readers should match effort and depth to the value and purpose of the work.

Source note: Essay “Of Studies”; Bacon distinguishes different depths and purposes of reading.
