"Venture All His Eggs In One Basket"
Context: Having freed a group of galley slaves, Don Quixote orders them to proceed to Toboso and tell his lady Dulcinea about the feats of her Knight. Sancho begs his master to leave that part of the country before the Holy Brotherhood, the rural constabulary, comes after them. He uses sophistry to persuade the warrior knight:
. . . to withdraw is not to run away, and to stay is no wise action, when there is more reason to fear than to hope; 'tis the part of a wise man to keep himself today for tomorrow, and not venture all his eggs in one basket. And for all I'm but a clown, or a bumpkin, as you may say, yet I'd have you to know I know what's what, and have always taken care of the main chance; therefore don't be ashamed of being ruled by me. . . .
