Rewiring the Brain – Dr. William Hurlbut

Jan 14, 2026

Dr. William Hurlbut, a physician and adjunct professor at Stanford, dives into the fascinating realm of neuroplasticity and neurotechnology. He explores how education and lifestyle can reshape the brain while cautioning about the risks of our digital culture and addictive behaviors. Dr. Hurlbut discusses the ethical implications of biotechnology in enhancing human capabilities, warning against the potential dangers of transhumanist goals. He emphasizes the need for a public dialogue that incorporates science, philosophy, and ethics to navigate the future of brain intervention.

ADVICE

Reserve Brain Implants For Clear Need

Be cautious about brain-computer implants; reserve them for clear therapeutic need.
Hurlbut personally rejects elective chips and urges prudence in adoption.

INSIGHT

Primitive Brain-to-Brain Links Exist

Early experiments show wireless brain-to-brain links between animals are possible.
Hurlbut suggests this could one day enable direct mind-to-mind communication.

INSIGHT

Deep Brain Stimulation’s Broad Reach

Deep brain stimulation powerfully treats Parkinson's and is explored for many psychiatric conditions.
Hurlbut highlights DBS's transformative clinical and speculative future uses.

About the Speakers:

William B. Hurlbut is a physician and Adjunct Professor in the Department of Neurobiology at Stanford University Medical Center. After receiving his undergraduate and medical training at Stanford, he completed postdoctoral studies in theology and medical ethics, studying with Robert Hamerton-Kelly, the Dean of the Chapel at Stanford, and subsequently with the Rev. Louis Bouyer of the Institut Catholique de Paris.

His primary areas of interest involve the ethical issues associated with advancing biomedical technology, the biological basis of moral awareness, and studies in the integration of theology and philosophy of biology. He was instrumental in establishing the first course in biomedical ethics at Stanford Medical Center and subsequently taught bioethics to over six thousand Stanford undergraduate students in the Program in Human Biology.

Dr. Hurlbut is the author of numerous publications on science and ethics including the co-edited volume Altruism and Altruistic Love: Science, Philosophy, and Religion in Dialogue (2002, Oxford University Press), and “Science, Religion and the Human Spirit” in the Oxford Handbook of Science and Religion. He has organized and co-chaired three multi-year interdisciplinary faculty projects at Stanford University, “Becoming Human: The Evolutionary Origins of Spiritual, Religious and Moral Awareness,” “Brain Mind and Emergence,” and the ongoing “The Boundaries of Humanity: Human, Animals, and Machines in the Age of Biotechnology.” In addition, he was Co-leader, together with U.C. Berkeley professor Jennifer Doudna of “The challenge and opportunity of gene editing: a project for reflection, deliberation and education.”
