This interdisciplinary monograph in philosophy of medicine examines models of explanation in health science and their relation with current medical trends, such as personalized and person-centered medicine. Medicine has provided challenging case studies for the general philosophy of science that have prompted rethinking of a wide range of philosophical notions   such as scientific law, theory and evidence   and contributed to the elaboration of pluralistic approaches to modeling, causality and explanation. The health sciences have increasingly recognized the role of philosophy of medicine as both a field of conceptual and methodological reflection, capable of addressing practical issues, and hence relevant for a proper understanding of the construction of medical knowledge, modeling practices, therapeutic strategies and preventive decisions.
