Universality and Modeling Limiting Behaviors

Most attempts to justify the use of idealized models to explain appeal to the accuracy of the model with respect to difference-making causes. In this paper, I argue for an alternative way to justify using idealized models to explain that appeals to universality classes. In support of this view, I show that scientific modelers seeking to explain stable limiting behaviors often explicitly appeal to universality classes in order to justify their use of idealized models to explain
