 Reflection on generics has also influenced debates about philosophical methodology. Mark Johnston (2016) suggests that certain well-known inadequacies of the “method of cases” in the philosophy of personal identity can be explained by the fact that we as philosophers have treated what is in fact merely generic-based—and thus exception-tolerating—knowledge of the application conditions of our concepts as if it were knowledge of universal necessary and sufficient conditions for the application of the relevant concepts. Johnston and Leslie (2012, 2019) rely on similar considerations to question the philosophical methodology known as the Canberra Plan. Lastly, Lerner and Leslie (2013) argue that a greater understanding of the role of generics in moral cognition undermines certain applications of the method of reflective equilibrium within normative ethics.
