Public Books on Pope Leo XIV’s AI Encyclical and the New Politics of Technology

A new Public Books essay takes an unexpected route into the artificial intelligence debate: through the first encyclical of Pope Leo XIV. The article says the pope’s document, "Magnifica Humanitas," is devoted to "Safeguarding the Human Person in the Time of Artificial Intelligence," and treats it as a major attempt to address the social consequences of AI from outside the usual circles of Silicon Valley and policy think tanks.

The author begins from unease. Hearing that the pope was weighing in on AI initially triggered dread, especially given religion’s uneven record with novelty and invention. But the essay quickly shifts from suspicion to admiration, arguing that Leo XIV’s intervention is neither a rejection of technology nor a theatrical moral panic. Instead, it is framed as an effort to confront the power structures behind AI: the corporate and governmental opacity, the speed of change, and the sense that the rules are being rewritten for the benefit of a few.

One reason the article finds the encyclical notable is its historical self-consciousness. Public Books points out that "Magnifica Humanitas" is dated exactly 135 years after Leo XIII’s "Rerum Novarum," the 1891 text associated with the Church’s social doctrine and its response to industrial capitalism and labor relations. That connection matters because Leo XIV is presented as reworking a familiar papal concern: how economic power shapes human life, and how institutions might respond when workers, consumers, and nearby communities are left with little leverage.

The essay identifies six major claims in the encyclical. First, Leo warns that AI development is driven largely by private, often transnational actors with resources greater than many governments possess. Second, he argues that genuine diversity of thought and experience is preferable to a corporate monoculture, and that the danger lies in a homogenizing logic that treats people as data and profit as the highest good. In this framing, the Church appears not as a barrier to diversity but as a defender of difference, listening, and dialogue against what Leo calls a “Babel syndrome.”

A third theme is education versus speed. Public Books highlights Leo’s insistence that AI should not encourage people to accept quick answers in place of patient thought, or information in place of understanding. The essay links this to Plato and to E. M. Forster’s "The Machine Stops," emphasizing Leo’s warning that cognitive offloading can weaken curiosity itself. The point is not only that AI can be used badly, but that it can train users to value immediacy over judgment.

The article then turns to justice. Leo, as described by Public Books, wants binding principles that would prevent new forms of exclusion, surveillance, and algorithmic discrimination. He is wary of post-humanist language that obscures the fact that human beings, not machines, remain responsible for decisions about labor, control, and exploitation. The essay stresses that the pope links these questions to older histories of slavery and colonialism, arguing that today’s AI systems can reproduce analogous hierarchies under newer alibis.

That historical argument gives the encyclical its sharpest edge. Public Books notes that Leo explicitly revisits the Church’s gradual condemnation of slavery and presents that history as a stain on Christian memory, but also as evidence that moral understanding can expand. For the essay’s author, this gives "Magnifica Humanitas" an unusual kind of force: not papal infallibility, but a sustained attempt to use words alone to challenge the political economy of AI. Whether readers agree with the pope or not, the piece suggests, the encyclical deserves attention because it enters the public argument over technology, labor, and human dignity on unusually broad terms.
