We cannot do without it, and yet we disgrace and vilify the same. It may be compared to a cage, the birds without despair to get in, and those within despair to get out.

[Il en advient ce qui se veiod aux cages: les oyseaux qui en sont dehors, desperent d’y entrer: et d’un pareil soing en sortir, ceuix qui sont au dedans.]

Michel de Montaigne (1533-1592) French essayist
“Upon Some Verses of Virgil,” Essays (1580-88)

On marriage. For more discussion of others who have used this metaphor, see here.
