substitutes in a quote

"Fantasies are more than substitutes for unpleasant reality they are also dress rehearsals, plans. All acts performed in the world begin in the imagination."

"Democracy is a form of government that substitutes election by the incompetent many for appointment by the corrupt few."

"There are no adequate substitutes for father, mother, and children bound together in a loving commitment to nurture and protect. No government, no matter how well-intentioned, can take the place of the family in the scheme of things."
