In 1881, Ibsen’s Ghosts was considered shocking for its critique of conventional morality and its unabashed treatment of venereal disease and religious hypocrisy, among other topics. While the specifics of the social issues that the characters grapple with are not pressing today—syphilis is a curable disease, a woman trying to leave an unhappy marriage is not unthinkable, nor is the idea that a person of high social rank might be a degenerate—moral hypocrisy, patriarchy, class resentment, and generational trauma are always ripe for the stage. The gripping, finely acted production of Ghosts now playing at Lincoln Center, directed by Jack O’Brien and adapted by Mark O’Rowe, threads this needle: it retains the historical setting (though with a framing device) and yet makes the moral debates feel like more than artifacts from another era.
