Bioethics and the value of disagreement.

What does it mean to be a bioethicist? How should the role(s) of bioethics be understood in the context of a world of intense value conflict and polarisation? Bioethics is-in all its various forms and traditions-potentially well-positioned to contribute to addressing many of the most pressing challenges of value polarisation and conflict in diverse societies. However, realising this potential is going to require moving beyond currently foregrounded methods and developing new models for engaging with moral disagreement. This paper proposes an approach, 'adversarial cooperation,' drawing on the concepts of 'adversarial collaboration' from the sciences and 'antagonistic cooperation' from the humanities. Adversarial cooperation aims to combine the rigour and structured methodology of adversarial collaboration with the cultural sensitivity and expansive vision of antagonistic cooperation. The paper also addresses key challenges to adversarial cooperation, including ethical considerations, tensions between substantive and procedural values, the problem of misinformation and the need for decision-making amidst ongoing disagreement. Ultimately, adversarial cooperation suggests a reimagining of bioethical expertise, emphasising skills in mediation, the arts and humanities and participatory decision-making alongside established philosophical competencies. This implies a model of normative bioethical authority grounded in the ability to facilitate inclusive and trustworthy processes of moral deliberation. Realising the potential of adversarial cooperation will require significant changes in bioethics training and practice, as well as a commitment to reflexivity, humility and the amplification of marginalised voices. By embracing this approach, bioethics can play a vital role in navigating the complex moral landscapes of pluralistic societies.
