Abstract
In 2012, the symposium "Christopher Boorse and the Philosophy of Medicine" was held at the University of Hamburg. The initial ideas presented at this event, which celebrated Chris's contribution to the development of what is now a vibrant area of research, especially to the theory of disease, form the core of the papers published in this issue. Similarly to what Robert Nozick once said about John Rawls's work, it can be demanded that philosophers of medicine must now either work within Boorse's theory or explain why not. It is simply the main contender in the so-called naturalist camp of contributions to the theory of disease. All of the papers in this issue address his approach in some respect, and all of them are friendly toward his theory up to a point. In this brief introduction, I try to extract common threads. In doing so, I focus on three issues that have the capacity to determine future debates. The first is the methodology of developing a theory of disease, especially what conceptual analysis amounts to and what it may achieve. The second is the issue of value-ladenness of the concepts of health and disease, a topic that has been at the forefront of the philosophical debate, but which -- to my mind -- has often been misunderstood. The third issue is the problem of the unity of medical terminology. We can ask whether there is only one core medical concept, be it "disease," "pathology," "disorder," "malady," or something else. Alternatively, we might propose different concepts for different purposes.
