What’s the difference between a disease and an illness? Is mental illness a disease? Is medicine a science or an art? In this course, we’ll explore these questions and more by way of an entry-level introduction to the fields of philosophy of medicine and philosophy of psychiatry. Through readings, podcasts, lecture, and discussions, we will explore philosophical topics concerning the health professions and health sciences that go beyond traditional bioethical problems, such as: concepts of disease and mental disorder, classification and kinds in medicine and psychiatry, explanation in medicine and psychiatry, medical evidence and evidence-based medicine, antipsychiatry and medical nihilism, and medical AI. Students will come away with an understanding of some of the fundamental philosophical problems underlying science and practice in medicine and psychiatry. This course is of particular interest to anyone curious about medicine, science, and/or philosophy. No previous knowledge in these topics will be assumed; students at all levels are encouraged to join. This course is part of a core sequence leading to certification in the Conceptual Foundations of Medicine Certificate Program and is a companion course to HPS 0613 (Morality and Medicine) but may be taken independently.
