A pair of analytical essays probe marriage as a social institution, combining pseudo-serious meditations and sharp satire. The first part offers theoretical reflections on laws, adultery, and the development of marital customs, arguing that marriage evolves with manners and exposing causes of conjugal unhappiness. The second assembles brief sketches and anecdotes that dramatize petty domestic conflicts, hypocrisy, and utility-driven sentiments. Tone shifts from mordant irony to occasional moments of genuine feeling, while legal, moral, and social observations recur throughout, mixing philosophical generalizations with lively, often judgmental portraits of private life.
