Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.
— Francis Bacon

Read not to contradict and confute, not to believe and take for granted, not 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 chewed quote

For it is with the mysteries of our religion, as with wholesome pills for the sick, which swallowed whole, have the virtue to cure; but chewed, are for the most part cast up again without effect.
— Thomas Hobbes

The secret to my success is that I bit off more than I could chew and chewed as fast as I could.
— Paul Hogan

In show business, you get chewed up and spit out.
— John Aniston
