Vulnerabilities in Kantian Constructivism: Why they Matter for Objective Normativity

Abstract

Abstract In section 1 we present moral constructivism as a metaphysical project which grounds moral norms in the attitude of valuing by rational agents. In section 2 we establish that Kantian Constructivism – opposed to Humean Constructivism – seeks objective and universal moral norms through a process of rational construction and ratification of norms that does not draw on any kind of subjective attitude of valuing. In section 3 we explore whether Kant is a moral constructivist or moral realist, arguing that he might be read as a proto-moral constructivist whose formulas impose standards of correctness upon our moral judgments, from which we formulate moral norms as necessary facts of reason. In section 4 we argue that: 1) vulnerabilities have moral relevance which adds merit to the project of finding objective moral norms, and 2) the inclusion of vulnerabilities as empirical contingencies is compatible with Kantian Constructivism. We do so by considering vulnerabilities a constitutive aspect of finite rational agents which must, therefore, be implied and considered in the process of moral construction.
