Philosophy of public health: Lessons from its history in England

Abstract

In a modern industrialized society it was essential for humankind to be protected by a strong medical presence, to establish a uniform system for public health everywhere in that society, to make public health independent from the welfare system, and to harmonize the relationship between personal hygienic rules and local authority rules. The society in Japan has developed on the basis of those four philosophical principles of public health, and has enabled the people to have the longest life expectancy in the world. However, the public health system in this society is now in a critical situation resulting from the long life expectancy. How can we rebuild the role of public health in this country? A society with a long life expectancy has to face a wide variety of health conditions. However, the health insurance system in Japan does not generally provide any service for a patient without specific symptoms. Consequently, to help people become aware of their own health condition, comprehensive public services such as general health check-ups, screening for cancers, and health counselling have been established locally by all 3250 municipal authorities. In promoting those services, people must learn how to draw the boundary-line between 'public' and 'private' in affairs of health to understand the importance of 'hygienic rules based on counsels for personal self-government', as Simon suggested 100 years ago, and health professionals must develop a public health system which depends not only on regulatory laws but also on scientific findings, as Rumsey advocated 150 years ago.
