Professor Neil Messer, Professor of Theological Bioethics at Baylor University in Texas, gives a fascinating lecture on neurotechnologies and the common good. Neil’s talk is expertly crafted to give everyone the science and the theological and ethical frameworks that we need to make the distinction between what might be considered as the good ‘therapeutic’ use of AI in health care and what might be simply ‘enhancement’ for enhancement’s sake. The questions raised by Neil’s research are relevant to everyone who is interested in protecting the common good of society – a key principle of Catholic Social Teaching which seeks to provide the good of all individuals and groups in our society.
