GHBN Summer School 2025

The 14th Annual GHBN Summer School was held in Cape Town in September 2025. 54 participants from 15 countries explored topics ranging from mental health and climate change; bioethics in contexts of conflict; ethical challenges faced by minority groups in medicine; and ethics and AI—including a lively debate on whether AI should guide end-of-life decisions—to comparative ethical frameworks, navigating between empirical and normative bioethics, and the future of the field amid today’s geopolitical shifts. A moving bioethics “pilgrimage” through the Castle of Good Hope was a highlight of the week. We left with renewed courage, sharper insight, deeper friendships, and a shared resolve to champion the value of bioethics.
