During the 18th century, cameralism spread through the lands of Prussia, the
Holy Roman Empire and beyond. Professorial chairs in Cameralism were also created in Sweden and
Denmark–Norway Foremost among the professors in cameralism was
Johann Heinrich Gottlob Justi (1717–1771), who linked Cameralism and the idea of natural law with each other. However, most cameralists were practitioners, not academics, and worked in the burgeoning bureaucracies sometimes supporting and other times shunning the science. Whether Cameralism was a technology that was applied to the different branches of the state and the economy decisively shaping it or whether it was a university science has been a major debate in modern research of Cameralism. Much debate has traditionally centered on exactly which writings classify as Cameralism. However, the work of Keith Tribe, who holds cameralism to be a university science disconnected from the actual activities of the administrators, sparked a counter-reaction and shifted the debate to include the practitioners of Cameralism. The shift is evident in the work of David Lindenfeld and Andre Wakefield, which illustrates the dynamics between theory and practice among cameralists. Although the precise legacy and nature of Cameralism remains disputed, it has affected modern public finance, not only by shaping the formation of state administration but also by giving rise to cameralistic accounting, a particular system predominately used in the German public sector which has outlived the rest of the science. The system has been deemed suitable for bookkeeping under conditions posed by public enterprises or services, such as constructing and maintaining infrastructure, and providing healthcare or education, since these services, if paid for, constitute a form of indirect taxation rather than a transaction on an open market. Justi based much of his inspiration for cameralistic studies to contemporary accounts of the Chinese imperial bureaucracy. The growth of cameralist studies, which played an important role in Prussian civil service training, may be traced to Justi's admiration for the
imperial examinations of China. Justi, like other cameralists, also lauded many Chinese public policies apart from its administrative system. == Cameralism in Prussia ==
