Don Quixote is a clear example of an idealist. On the other hand, Don Quixote's squire Sancho Panza, is a sarcastic man that function as a realist and helps his master to see the world as it is. For instance, Sancho Panza warned Don Quixote when he tried to fight "ferocious giants" that were in fact windmills.
