Modern feminism has spent the last century fighting to give women the freedom to have jurisdiction over their voting rights, their ambitions, and their bodies. Some of the movement has done great good. But some of it has done great harm by reinforcing a common and problematic idea: that women’s rights ought to be understood in terms of property rights. “Owning your own body” seems like a natural enough freedom—who wouldn’t want it?—but in fact, it delivers a reductionistic conception of human flourishing that fails both women and the unborn.
