The aim of this session is to explain why a conception of person-centred care based on Phenomenology needs to incorporate profound elements from Naturalism – and why both these predominant knowledge cultures need to give up their foundationalist claims – in order to cope with the conditions that make us human. Starting from my book Science as a Quest for Truth: The Interpretation Lab (2019, in English 2024), I will elaborate on an alternative “broken” ontology that invites philosophy of science to focus on “laboratories of interpretations” and practical knowledge as a guarantee for a sustainable quest for truth. Person-centred care, acknowledged as an ethical aim combining teleological and deontological perspectives, motivates a new focus on the well-informed judgement of the profession in health care. Thus, the two questions, “What makes us human?” and “What is science?”, need to be correlated if we really are interested in “knowledge(s) and innovations for health in changing societies” – as well as changing sciences! This particular convergent conceptualization of both person-centred care and philosophy of science, mainly inspired by Paul Ricoeur (1913-2005), has also been one of the sources of inspiration within the Gothenburg Centre for Person-Centred Care.
