"Crafty men condemn studies; simple men admire them; and wise men use them: for they teach not their own use: but that is a wisdom without them, and above them, won by observation. Read not to contradict and confute; not to believe and take for granted; nor to find talk and discourse; 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. Some books also may be ready by deputy, and abstracts made of them by others; but that would be only in the less important arguments, and the meaner sort of books; else distilled books are like common distilled water, flashy things. Reading maketh a full man, conference a ready man, and writing an exact man. And, therefore if a man write little, he had need have a great memory; if he confer little, he had need have a present wit; and if he read little, he had need have much cunning, to seem to know that he doth not."
-Sir Francis Bacon
