This document discusses the intersection of medicine and the philosophy of science. It argues that medicine should be broadly defined to include clinical practice, public health, epidemiology, and various medical theories and approaches. The philosophy of science encompasses analytic philosophy, history and philosophy of science, sociology of science, and critical approaches. The document examines philosophical questions in medicine around causation, explanation of health and disease, different types of evidence, and how qualitative and quantitative data can be integrated. It proposes studying causation in medicine through a "causal mosaic" that maps out causal theories, scientific and philosophical challenges, and accounts of causation, mechanisms, processes and other concepts.
