Consciousness, Neurotechnology, and the Future of the Human Person (Lecture 3)

We've spent two lectures arguing machines can't become persons. They lack consciousness and moral agency. They cannot love. This lecture flips the question inside out. What happens when human beings start integrating more deeply with machines, not in some science-fiction future, but right now, in labs and clinics across Europe and North America? I work through two cases in detail. Deep brain stimulation, where the unsettling question is whether a device that changes your personality is giving you back yourself or replacing it. Brain-computer interfaces, where agency gets complicated once a device predicts your intention before you've finished forming it. A third case, memory technology, asks whether erasing a shameful memory relieves suffering or erases the conscience that was supposed to learn from it. Underneath all three sits transhumanism: the assumption that the human being, as currently built, is a problem to be engineered away. I argue the opposite. Our vulnerability and our finitude are not defects to be patched. Neither is the fact that we forget. These are part of what makes moral life possible in the first place. Pope Leo XIV's 2026 encyclical Magnifica Humanitas makes exactly this point the anthropological foundation of the entire document. This is Lecture 3 in a series drawn from my forthcoming book, Vigilant Hope: Preserving Human Dignity in an Age of Artificial Intelligence (Ascension Press). Subscribe for Lecture 4, where we come down from philosophy to the machine room and look at what a large language model actually is, one token at a time. Books Can AI Ever Be Human?
