Health magic lantern slides focus on health as an object of scientific study; that is, as a state of physical, mental and social (and therefore moral) well-being, which is not only a consequence of the absence of disease. These slides focus on promoting better health in the population and endorse it as a process that allows people to increase control over their health in order to improve it. For that reason, an emphasis in this genre is the dissemination of healthy public policies, the development of personal skills (including those of moral character or ‘good’ behavior) and also the reinforcement of common action and the use of public health services. The promotion of health draws on many other disciplines besides Medicine, such as Sociology, Psychology, Education, Teaching or Law.
