In quite modern times, that is to say, since about the period of the French Revolution, an idea has grown up that marriage should be the outcome of romantic love. Most moderns, at any rate in English-speaking countries, take this for granted, and have no idea that not long ago it was a revolutionary innovation.
... In America, where the romantic view of marriage has been taken more seriously than anywhere else, and where law and custom alike are based upon the dreams of spinsters, the result has been an extreme prevalence of divorce and an extreme rarity of happy marriages.
