Book excerpt: Public Health Policy and Ethics brings together philosophers and practitioners to address the foundations and principles upon which public health policy may be advanced. What is the basis that justifies public health in the first place? Why should individuals be disadvantaged for the sake of the group? How do policy concerns and clinical practice work together and work against each other? Can the boundaries of public health be extended to include social ills that are amenable to group-dynamic solutions? These are some of the crucial questions that form the core of this volume of original essays sure to cause practitioners to engage in a critical re-evaluation of the role of ethics in public health policy. This volume is unique because of its philosophical approach. It develops a theoretical basis for public health and then examines cutting-edge issues of practice that include social and political issues of public health. In this way the book extends the usual purview of public health. Public Health Policy and Ethics is of interest to those working in public health policy, ethics and social philosophy. It may be used as a textbook for courses on public health policy and ethics, medical ethics, social philosophy and applied or public philosophy.
