I sometimes feel a bit like Don Quixote, who read hundreds of books on chivalry and knighthood and then foolishly determined to wander the world imitating them by righting wrongs, helping ladies in distress, and bringing nobility back to the people along his path. Quixote often scolded Sancho Panza, his infinitely cleverer companion, for laughing at his expense, talking too much, and questioning his actions. A wickedly funny character created by Miguel de Cervantes for his famous novel by the same name, Don Quixote is perhaps the greatest idealist in history, fictional or true. He is at times a holy fool, a saint (according to W. H. Auden), and a mirror image of each person who tries hard to be something he or she has read about in books.
Don Quixote is considered foolish precisely because he wholeheartedly believes that what he has read in books about medieval knights actually happened. He is egotistical because he sincerely believes that he, too, can be a gallant knight. But irony is rich throughout the novel, as we are never quite sure if Don Quixote might actually be the sanest person around. He never seems to know that he is playing a role, as in a play—because a knight is very clearly not what Don Quixote is, deep down, with all of his bumbling and mistakes.
Perhaps such role-playing is what we all are doing who read the Lives of saints, at least those of us who are trying to imitate the explorers and exemplars who have gone before us.
