Resumen de Constitutive rules as a logical problem in the origin of John Rawls’ moral philosophy

Pablo Aguayo Westwood

• This article offers a critical review of John Rawls’s 1955 essay Two Concepts of Rules and argues thata full understanding of his mature work requires examining his early philosophical development.The central hypothesis posits that Rawls’s analysis of constitutive rules is essential for understandingthe epistemic foundations of his later theory of justice. A key distinction is that drawn betweenjustifying an action that falls within a rule (or practice) and justifying the rule itself. This distinctionallowed Rawls to defend utilitarianism against its critics, highlighting their logical misunderstandingof how this theory evaluates actions. Furthermore, the article argues that Rawls’s early concern withpractices and social institutions directly influenced his subsequent interest in the basic structure of society, developed in A Theory of Justice. Ultimately, it reveals Rawls’s nascent attention to theevaluation of systems of rules that shape social practices, rather than focusing solely on individualactions, representing a crucial step in the elaboration of his theory.
