Don Quixote’s madness stems from his literal reading of books of chivalric romance and his deluded belief that he actually is a knight errant. He rides out into the realist world of Cervantes’ novel with a lofty dedication, inflicting his good intentions on others, and time and again is buffeted by stubborn reality. Quixote is generous, brave, courteous, resilient, knowledgeable, eloquent, and a complete idiot. I wrote about Part 1 of the novel last month. He rides out again, in Part 2, with his trusty squire Sancho Panza, having been revived after a month’s rest and the consumption of six hundred eggs.
