In a new postmodern and transdisciplinary understanding of public health, the previously defined boundaries of the discipline are seen as ones that proliferate, invite crossing, and constantly assign themselves a new expiration date. The narrow framework that is artificially imposed around the currently very modest spectrum of subjects unnecessarily restricts the view of health. In doing so, it even obstructs the universally required concern for the health of the population, as called for by the WHO in 1986. In an innovative initiative, the contributors gather those disciplines that have so far not been adequately considered in health science discussions. In this way, they open the academic discourse and provide a glimpse into a health science without borders.
