In recent times, health politics has crystallized more and more into a independent branch of social politics. Health as well as disease, have become a central topic of public and individual discussion. A elucidation of the relevant concepts seems to be urgently required. The article, starting from the well-known WHO definition of health, attempts a critical discussion of the concepts of "health" and "disease". It becomes apparent that, according to the present state of knowledge, neither can be conclusively defined, by either medical or psychic scientific methods. The material is subjected rather to a constant change decisively dependent on psychic currents at the time in question.
