 This argument engages the history of theory-change in science in a substantial way. As Hesse admitted, the Principle of No Privilege arises “from accepting the induction from the history of science” (1976: 271). Hesse’s argument starts with the historical premise that, as science grows over time, there has been a recognizable pattern of change in the ‘ontology of fundamental entities and properties’ posited by scientific theories. Assuming, then, the Principle of No Privilege, it is argued that current theories too will be subjected to a radical change in the ontology of the entities and properties they posit. Hence, current theories are as false as the past ones.
