Abstract

Searle represents constitutive norms as count-as conditionals, written as 'X counts as Y in context C'. Grossi et al. study a class of these conditionals as 'in context C, X is classified as Y'. In this paper we propose a generalization of this relation among count-as conditionals, classification and context, by defining a class of count-as conditionals as 'X in context C0 is classified as Y in context C'. We show that if context C0 can be different from context C, then we can represent a larger class of examples, and we have a weaker logic of count-as conditionals.
