Reading maketh a full man and writing an exact man. Read not to contradict and confute; nor to believe and take for granted; but to weigh and consider. Some books are to be tasted, others to be 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.
