Early in Don Quixote, our hero's niece and other alarmed members of society set about to burn books that they believe caused his "insanity". Whether Don Quixote is actually the insane one is a question I don't set about answering just yet.
Book burning is something I never can agree with. After all, is it music and books that lead our ideas and our actions, or are these simply forms of speech? (And free speech is protected.) It is the personal choice to act in some manner, and the responsibility falls upon the doer, not upon pieces of paper and musical arrangements.
You can't kill an idea... The burning of the books of knights of old, of chivalry, of adventure, of holy nonsense, will not change Don Quixote's character or or his heartfelt, inherent beliefs.
