G.k. Chesterton said this quote

But though I might fill the world with dragons I never had the slighest real doubt that heroes ought to fight with dragons. I must stop to challenge many child-lovers for cruelty to children. It is quite false to say that the child dislikes the fable because it is moral. Very often he likes the moral more than the fable. Adults are reading their own weary mockery into a mind still vigorous enough to be entirely serious.
