Adventures of Don Quixote

Duke:
Beware, gentle knight. There is no greater monster than reason.

Don Quixote:
Happy the days and happy the centuries to which the ancients gave the name of "golden". Those who lived then did not know the meaning of those fateful words "thine" and "mine"... And it is only in these detestable, corrupted times that a knight-errant is needed...

Officer of the Holy Brotherhood:
We are releasing this troublemaker into your care, and you will be responsible for any further misdeeds that he may commit.

Village Priest:
But he's mad, poor fellow, not wicked. Half the rooms in his brain are vacant.
