Law professor David Forte, in his brief piece in The Meaning of Marriage on the Framers' attitude to marriage, offers a helpful aside.
The American Revolution was made by practical Aristotelians, and therefore was pro-family. They saw the family as one of the seedbeds of virtue necessary to make worthy citizens of a republic.
The French Revolution, by contrast, was made by utopian Platonists, and therefore was anti-family. They saw the family as standing against the state, which alone has the capacity to educate citizens to virtue.
