Read not to contradict and confute; nor 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.
~ Francis Bacon ~
My high school teacher made us read this essay by Francis Bacon, and this quote- to me- is breathtaking.
